Dear Readers of the Sanitary Engineering Newsletter,

Now that a large disaster is developing in Mozambique, everything that we do in the water sector looks marginal. Why removing pharmaceuticals from drinking water, while people are dying from cholera? Why thinking of water reclamation while entire districts are flooded? Why recovering energy from water, while, in Beira, the drinking water supply pumps completely stopped? The situation in Mozambique is horrible and only a week after the cyclone, the information came in its entire dimension to us. This was partly because during this time, the area was fully isolated from the rest of the world. Two of my PhD students have family in Beira. They only were notified 5 days after the disaster that they were fine and survived the cyclone and the floods.
Little can be done about these climatic circumstances and I do not know if a Deltaplan, as we have here in the Netherlands, will work. The area is huge, the population density in the cities large, but in the surrounding, rural areas very low. In fact what happened is that not only climate change posed this problem, but mainly the tremendous population growth (Mozambique grew in 30 years with about 50%) and urbanisation provoked an uncontrolled expansion of the cities, with inadequate infrastructure and insufficient resilience against extreme circumstances.
What is needed now is emergency aid of course. Therefore we wish Marij Zwart all the best in her task at UNICEF to combat cholera outbreaks in Chimoio. However, hopefully, this disaster will be the beginning of an alternative Deltaplan for Mozambique, not only focussing on avoiding flooding, but on making the city (and surrounding areas) more resilient. In addition, it gives the opportunity to adapt the (water) infrastructure to the new circumstances, also introducing new concepts of e.g. multiple use in the urban water cycle. Hopefully, our research in Mozambique and the capacity building projects that we have, with Mozambican counterparts as the University Eduardo Mondlane, FIPAG, Agência de Vale do Zambeze, can give input to the rehabilitation and re-structuring of the area between Beira and Chimoio, making these activities on the long run relevant.
More activities of the Section Sanitary Engineering of TU Delft can be found in this Newsletter. Specially check the abstract of the three PhD students who are going to defend in the coming period. Also we are very happy to introduce the new, young, tenure track assistant professor, Frederik Zietzschmann, who specialises in adsorption processes.  We wish you much reading pleasure and are always open for debate and new initiatives/projects to develop together with you.

New Year's conference, the "Vakantiecursus " 2019

On January 11, the 71st edition of our traditional Vakantiecursus was held at our faculty. The New Year’s conference is the only conference in the Dutch language and, as always, many participants from Dutch institutes and companies visited our department to celebrate the kick-off of the water year 2019. In fact, nearly 400 participants enjoyed the programme in lecture rooms A and B. The theme of the 71st edition was ‘Meer tijd voor waterkwaliteit’, putting the water quality issue at a central spot. Professor Dragan Savic, director of KWR started the day in lecture hall A, calling for a stronger cooperation between the institutes and universities like TU Delft to address the upcoming water quality matters in a more integrated manner. Chemical impurities in drinking water keep on challenging the water companies but also antibiotic resistance and microbial safety calls for an integrated approach. Delfland’s new ‘Dijkgraaf’ Piet Hein Daverveldt gave various examples in which Delfland works on quality improvement of the many surface waters under pressure, particularly in the Westland. In hall B professor Suzanne Steele Dunne started the day, discussing novel tools to better predict water availability and water flows using radar and remote sensing techniques. The predictability of water quantity during rain events was further discussed by Dr. Geert Lenderink of the KNMI unravelling the complexity of such events. After the break in hall A, Leo Hendriks from the Water Company Drenthe made an appeal for personal attention and relations as driver for success. With his guitar he impressed the water world and within 30 minutes everybody was vocally sharing his message! His contribution was followed by Joke Cuperus from PWN (Province of Northern Holland) who stressed the importance of a strong water sector clustered in the top knowledge institute “Water”. The successful cross sectoral cooperation within the water sector has put the Netherlands way upfront as guiding country and as knowledge provider. In hall B, Dr. Marjolijn Haasnoot of Deltares warned for the upcoming and accelerated sea level rise as game changer for our water management agenda. Hereafter, professor Nick van de Giesen took us to the African continent and illustrated the importance of high quantities of reliable data to increase our insights in water availability. New technical and cost-efficient developments were discussed, which are indispensable for any predictive modelling.
In addition to the mentioned speakers, Bachelor, Master and PhD students, revealed with their very inspiring flash presentations the state of the art of our research at TU Delft. After the lunch we were informed by Dr. Julie Grelot about the experiences in Switzerland with quaternary treatment of sewage effluents for removing micro-pollutants. Will this be indicative for our approach to address emerging contaminants?
As final speaker, our astronaut Andre Kuipers invited us to board his Soyuz space craft to visit the international space station. Before this travel he showed a compilation of satellite images measuring changes on our earth surface in the past decades. Melting glaciers, accumulating fine dust, increased nitrogen emissions, changes in the ozone layers and deforestation around the globe was displayed. The changes on our planet’s surface and atmosphere on such a short time are simply scary, calling for immediate action. Hereafter the real take off was realised and the entire lecture hall travelled with Andre several times around the world. Amazing sights of our planet but also the normal life in the space station made a deep impression. For a sanitary engineering, showering in space using floating water drops is more than just a challenge, the same is true for visiting toilets realising that al water that is excreted needs to be recycled to become drinking water again. A future approach for water scarce countries on the surface of our planet??

IWA Anaerobic Digestion conference 16

Early bird tariff is valid till April 1st



The 16th Anaerobic Digestion conference will be held from the 23rd to the 27th of June this summer in the Aula conference centre in Delft. The preparations are at top gear and it is the most shared term between us during the past weeks. Therefore, we would like to give you a little update on the progress of this exciting and rapidly approaching event.
In December we received 743 abstracts that were reviewed by a large team of international experts from the field. Each abstract received 3 judgments, ranging from “not suitable for this conference” to “will be an excellent presentation”. The start of this year was in the scope of evaluating all the reviews and order the abstract, to come to a balanced program divided among the different themes of the conference (Box 1). In the meantime, we brainstormed about the key note speakers, the invited speakers, gender equality among speakers, and the global representation of these speakers. In the end we found and invited a very nice representation of older and more established scientists, and young and upcoming talents, who all accepted our invitations. Also the majority of the abstract presenters accepted and registered at the moment of writing this text, so the program is almost complete, with 9 keynote speakers, 15 invited speakers, 180 presentations in 3 parallel sessions and over 400 posters. The current number of registrations is around 180 and everyday new registrations are added.

The program around the AD16 conference will already start on Thursday the 20th of June with 4 workshops: 2 in Gent, 1 in Wageningen and 1 in Delft.
  1. Start: How to start a good AD research? Basic techniques (BMP and SMA tests), as well as activity measurements through more advanced techniques and how to deal with complex feeds to your AD process will be discussed (Key organizer: KU Leuven, Ilse Smets, Raf Dewil and Lise Appels)
  2. Predict-it: This workshop deals with modelling of AD processes: from the future of ADM1, and the developments required, to thermodynamic state analysis and flux analysis of key metabolic process. (Key organizer: TU Delft, Robbert Kleerebezem)
  3. Change: If you want to develop into an entrepreneur, commercialising your research, this workshop is a good start. Start-life will support you to develop your enterpreneurial competences, to further stimulate your own business ideas, around the central topic ‘closed resource cycles in a one million city’ (Key organiser: Wageningen University and research: Annemiek ter Heijne, David Strik and Gitte Schober).
  4. Magic: Methane is a wonderful molecule: a small bag of carbon and energy. This workshop tells about emerging applications of methane; making more methane (power-to-gas), grid injection and production of attractive new compounds such as feed and food protein, carbon monoxide… on site . (Key organiser: Gent University:Korneel Rabaey)
The workshops will finish on Saturday, where after the participants can travel to Delft. On Sunday, there will be some side events organised (keep an eye on the webpage), followed by the official opening reception and registration starts from 15.30. Speakers at the opening ceremony will discuss Anaerobic Digestion in social (Kala Vairavamoorty - IWA executive director), economical (Paques and Biothane-Veolia) and scientific (Willy Verstraete – Gent University) context. During the following reception, old friends and colleagues from all over the world can be met under the joy of a Belgium beer, brewed from RO-treated wastewater.
On Monday we will start with the official program, which we will close on Wednesday night with a dinner and party at one of the Beach restaurants in Scheveningen. On Thursday, you can enjoy technical tours to different anaerobic treatment plants in the Netherlands, or take a touristic tour with your colleagues to one of the Dutch highlights. One of the special events, that is organised on Tuesday night is the arts and science event, with two extra ordinary artists that combine their knowledge of natural systems with art (Ivan Henriques and Teresa van Dongen).
The coming months, we will be busy with conference bags, catering, program, transport, and answering emails, together with our co-organisers from Gent (Korneel Rabaey, and Jo de Vrieze), from IWC and from the KNW-ACE theme group. We are still looking for sponsors, so if you would like to sponsor this event and get an exhibition place, or just add some nice goodies to our conference bag, please contact us.

First keynote lecture Professor Kapelan

I have given my first invited talks since joining TU Delft in September last year. The first talk was a keynote lecture delivered at the International Symposium on Water Systems Operation (ISWSO) in Beijing, China in October last year. The second talk was the invited lecture at the 10th International Perspective on Water Resources and the Environment (IPWE) conference held in Cartagena, Colombia in December 2018. As part of this conference I have also participated in the water reuse panel. The final talk was a plenary (keynote) lecture delivered as part of the “Global water security: integrated modelling and adaptive management” series of lectures organised by the Croucher Advanced Study Institute in Hong Kong in January 2019.
The three lectures presented a range of hydroinformatics type smart water technologies that I have been working on over the years. All talks were received well and generated a lot of interests with potential for future collaborations. The technologies presented are based on processing big data coming from various sensors in drinking and waste water systems with the aim to extract useful information for improved operation and management of these systems. Examples include a technology for the automated detection, location and response to pipe bursts, equipment and other failures in drinking water systems, technology for automated sewer condition assessment, methodology for automated detection of discolouration events by processing flow and turbidity data and methodology for automated detection of blockage and collapses in waste and storm water systems. A couple of these technologies are now used by large water utilities in the UK.

New colleague : Frederik Zietzschmann

"I am very happy to have joined the Sanitary Engineering section in October 2018 as a tenure track Assistant Professor for physical-chemical water treatment processes. Previously, I worked at the chair of Water Quality Control at TU Berlin (Germany) with Prof. Jekel and at the Berlin Centre of Competence for Water. I worked in several research projects focusing on advanced water treatment to remove emerging contaminants like organic micro-pollutants and microplastics. I also work with the German Association for Water, Wastewater and Waste (DWA) on activated carbon applications as an advanced water treatment technology.
My research mainly focuses on organic micro-pollutants which originate from various pharmaceutical, industrial, and agricultural chemicals being discharged into aqueous environments, e.g. by wastewater treatment plants. I use state-of-the-art measurement techniques, mainly liquid chromatography-mass spectrometry, to assess the potentials of advanced water treatment techniques to remove organic micro-pollutants. I developed several practical methods to understand and predict organic micro-pollutant removals in different water matrices whose dissolved organic matter compositions can vary strongly, having variable impacts on treatment efficiencies.
In my new position at TU Delft, I want to develop new efficient and ecological adsorbent materials for micro-pollutant removal. I further want to improve the current methods for modelling and predicting the removability of micro-pollutants by different technologies, since many operators still rely on repeated laboratory tests which are time-consuming and expensive. I am also curious in any other potential water-related research where my background could be helpful, so please feel free to contact me about ideas on technologies, analytical methods, experimental designs etc. In particular, we just recently obtained a new liquid chromatography-mass spectrometer which will help us detecting various non-volatile organics in aqueous matrices. We are currently developing the first methods for pharmaceuticals and pesticides but many more may follow!
I am looking forward to working with all the nice colleagues at the department and am usually always available for a short chat, just have a look in room 4.52.

Kind Regards,


Frederik Zietzschman

Research projects

Ceramic nanofiltration for direct treatment of municipal sewage


Promotor: prof. dr. ir. Luuk Rietveld
Co-promotor: dr. ir. Bas Heijman
Worldwide population growth, water scarcity, and climate change contribute to an urgent need for alternative water sources for irrigation water, industry water, and, in some countries even, drinking water. The implementation of municipal sewage reclamation is an upcoming trend in water treatment. The use of municipal sewage has the advantage of keeping the water circles small. Moreover, more is to gain from municipal sewage: nutrients and energy are abundantly present in this water and could potentially be recovered too.
The purpose of this research was to study the potential of the application of ceramic nanofiltration for treatment of municipal sewage. Ceramic NF membranes were chosen because of their high mechanical strength and high chemical and thermal resistance. These membranes are expected not to be damaged by high pressures, temperatures, concentration of chemicals, which enables vigorous chemical cleaning of the membranes, and they are prone to less irreversible fouling compare to polymeric NF. This research was divided into four parts. 
First, a preliminary pilot study showed that ceramic nanofiltration membranes have potential for direct treatment of municipal sewage as pretreatment for reverse osmosis. Second, the quality and robustness was thoroughly researched and was lower on some expects than expected. Third, the phosphate retention during ceramic NF was notable effected by pH, multivalent counter ions, and a fouling layer on the membrane surface. Fourth, several fouling control method were tested using ceramic NF: the highest flux was maintain when applying reaction based precoat, resulting in the net highest water production.

Arsenic Removal for Drinking Water Production in Rural Nicaraguan Communities
Promotors: prof. dr. ir. Luuk Rietveld & dr. ir. Doris van Halem

Long-term intake of water with high concentrations of As can cause the development of Arsenicosis (arsenic poisoning). The World Health Organization has recommended a provisional concentration of arsenic in drinking water not exceeding 10 μg As /L. In 1996 the first documented case of As poisoning in a Nicaraguan ’rural community was reported, 125 people were found with the characteristic skin lesions of chronic Arsenicosis, after ingesting water from a public well with a As concentration of 132 times the permissible level. In 2011 the World Health Organization determined that drinking water sources  influenced by the geothermal fields of the Telica volcano were used by rural communities in the western part of the country. The arsenic concentration in this area ranges between 50 to 900 µg/l and the average temperature is about 34oC. Polyamide negatively-charge nanofiltration (NF) systems have consistently demonstrated a high efficiency for the removal of As(V) from water with ambient temperatures, and it is known from industrial applications that NF is capable of treating water at temperatures up to 65°C. Therefore, the use of nanofiltration (NF) for As removal in rural areas of Nicaragua was studied, where drinking water sources are high in temperature due to geothermal influence. The research methodology consists of three components: (1) review of As occurrence and mobilization mechanisms in Nicaragua, with an emphasis on non-peer-reviewed data sources at local institutions, (2) experimental research conducted at the water laboratory of TU Delft, (3) NF pilot plant research in a Nicaraguan rural community exposed to As-rich drinking water sources due to geothermally influences.
In Nicaragua volcanic rocks and geothermal fluids which are distributed across the country are likely to be the main source of As contamination in drinking water. Depending on the local geochemical conditions, As may have directly entered into the groundwater by geothermally-influenced water bodies, or indirectly by reductive dissolution or alkali desorption. The As contamination has been reported in 80 rural communities, Arsenicosis has been identified in at least six of those communities.
 During the lab-scale experiments the effect of high temperatures (25-50oC), as found in geothermally influenced source waters, on the rejection of monovalent H2AsO4- and divalent HAsO42- species (at pH 6, 7 and 8) in a multi-component solution containing Cl- (0.6mM) and HCO3- (0.11 to 1mM) was studied using two commercially available NF polyamide membranes (Dow NF270 and Alfa Laval NF). As rejection by Dow NF270 increased from 87% (25oC) up to 97% and 93% for mono and divalent As(V), respectively, at 50oC. As rejection by Alfa Laval was enhanced from 80 to 86% for monovalent and from 91 to 97% for divalent As(V) species, respectively, as a result of temperature increase. These results were in contrast to previous studies, conducted with deionized water, where it was found that temperature increase had a negative effect on As(V) rejection. However, The enhancement of As(V) rejection with NF-A at higher temperatures was not attributed to variation in the charge of the membrane (the zeta potential was constant), but to the enlargement of the pore size (MWCO increased) and, as a result, the increase of the mass transfer of Cl- and HCO3- across the membrane.
The last component of the thesis consisted of a NF pilot plant, powered by solar panels, that was built and operated in a rural community in Nicaragua, exposed to As-rich drinking water sources due to geothermal influences. The effect of operational parameters such as different fluxes (16, 23 & 30 L/m2h) and temperatures (31, 35 & 43oC) on the rejection of As(V) during nanofiltration (NF) of natural geothermal influenced groundwater in Nicaragua were investigated. The results showed that even at high temperatures it was possible to obtain high rejection of As(V) (87-90%) during NF (at recovery of 10% and flux of 16 L/m2h) of geothermal influenced groundwater, with the additional advantage of requiring low operating pressures (1.2 bar~12mwc). The permeate concentration (~ 5 µg/L) complied with the WHO guideline for drinking water and the concentrate (~ 55 µg/L) could be used by local villagers for daily activities (e.g., laundry and bathing). For all investigated fluxes and temperatures, the order of rejection of As(V) (as HAsO42-), compared with the other anions, could be interpreted on the basis of its charge, hydrated radius and hydration free energy. At lower temperatures (31 and 35oC) permeate quality improved slightly (~ 3 µg/L), but, although an increased temperature had a negative effect on the As rejection (contrary to the results obtained from the lab-scale experiments), As concentrations in the permeate never exceeded 5 µg/L, while the required transmembrane pressure (TMP) dropped - depending on the flux – from 0.5 to 1bar. This decrease in required pressure might be of huge benefit at isolated, rural locations, where electricity is scarce.
Altogether this study has illustrated that NF membranes can be an effective barrier for As(V) in rural Nicaragua – also at high water temperatures.

Monitoring and Operation of Ozonation - BAC Filtration
 
Water companies are facing increased challenges due to changes in feed water qualities and increased (micro-) pollution loads. This continuous changing source water requires improved monitoring and operation of the WTP, anticipating on the disturbances in the process. Ozonation and BAC filtration processes are susceptible to such changes in the feed water quality. At the same time, these processes have several control options to counteract the changes and a high level of interaction between the two processes exists.
 
In this thesis it was shown that the current monitoring strategy of ozonation-BAC filtration could be improved through implementation of an established design methodology in combination with the developed algorithms allowing for on-line estimation of AOC, bromate and Ct-value around ozonation, based on the measured change in UV-Vis spectrum. The operation of BAC filters could be improved through a better understanding of the direct response of the BAC filters to a change in feed water quality and the use of simplified models to optimize the operational strategy around backwashing of BAC filters.

UPLC-MS
Ultra high performance liquid chromatography-tandem mass spectrometer 

"In early 2019, a new ultra high performance liquid chromatography-
tandem mass spectrometer (UPLC-MS or "LC-MS") was installed at the Water Management Department. Staff training for operation and method development is currently ongoing. The device is highly versatile and will therefore be of substantial use for the Department. Potential applications include all projects dealing with organic compounds like pharmaceuticals, pesticides, industrial chemicals, and drugs, occurring at very low concentrations in real water samples.

LC-MS is the state-of-the-art analytical method for accurate and precise quantification of non-volatile organic compounds at ultra low concentrations in aqueous matrices (down to ng/L) - often referred to as "organic micro-pollutants". This technique has been used by various groups around the world on countless occasions in recent and ongoing research projects, finding low-level pollutions by organic contaminants in nearly all parts of the water cycle, including wastewaters and treatment plant effluents, surface waters, groundwaters, and even drinking waters. These alarming findings are underlining that there are still manifold contaminations which are not yet sufficiently examined - and that there is likely an even higher number of such pollutants which have not yet been found. Another application field of LC-MS is quantifying transformation products of aqueous organic compounds, additionally substantiating the need for comprehensively understanding the environmental fate of anthropogenic organic substances. Several research groups are trying to optimize the microbial removal of organic micro-pollutants in technological and natural barriers but many of these pollutants are too recalcitrant. All of these findings are strongly driving the intensifying discussion of equipping water treatment facilities with advanced treatment stages, e.g. adsorption and oxidation.

LC-MS combines several highly accurate analytical steps and ultra-sensitive detection to unequivocally measure specific organic substances in the presence of thousands of other compounds. No other analytical technique can accurately and precisely target and quantify individual substances in the presence of numerous other, partially very similar, compounds. Another great advantage of LC-MS is the simultaneous measurement of highly diverse substances (different molecular structures, properties, sizes etc.) in a single run of ~5 minutes.

For questions regarding applications and potentials of LC-MS, and related research ideas, please contact Frederik Zietzschmann."
Showcasing the potential of underground rainwater storage and reuse for climate adaptation in European cities.

Urban areas across Europe are increasingly facing flooding due to peak rainfall, as well as water shortages as a result of longer periods of drought. The current centralised urban drainage and supply systems are separate tasks managed by different stakeholders. Replacing or upgrading the current urban water systems to meet the 21st century standards in response to climate change is labour and capital intensive. Bluebloqs is a nature-based and scalable solution for decentralised water management in urban areas, avoiding flooded streets and guaranteeing freshwater availability during dry periods. By locally collecting, treating and storing stormwater through an integrated circular system, stormwater can be reused to meet the local freshwater demand.
Bluebloqs combines innovative bio-filtration and deep infiltration technologies through a modular system for stormwater treatment, storage and reuse. Collected urban run-off is treated by means of bio-filtration techniques, combining slow sand filters and vertical flow constructed wetlands. The purified water is stored in the subsurface via infiltration wells, from where it can be recovered for different urban applications: e.g. irrigation, industrial processes or combating urban heat. Developed by startup Field Factors in collaboration with Delft University of Technology and KWR Water, this innovation has been tested at living lab The Green Village and implemented in a full-scale pilot application in the Urban Waterbuffer project at the Sparta Stadium in Rotterdam.
To test and showcase the upscaling potential of this innovation in Europe, a consortium of knowledge institutes, businesses, public organisations and cities has received EIT funding from the Climate KIC Demonstrator Programme. In a 2-year project, Delft University of Technology, Aquafin, Technical University of Madrid, KU Leuven, KWR Water, Field Factors, I-Catalist, Hoogheemraadschap van Delfland, will collectively work to accelerate the urban transition towards a decentralised grid of circular water systems, making cities climate resilient.
The innovation will be implemented on four demonstration sites: 2 large scale pilots in the Dutch cities Someren and Pijnacker-Nootdorp, a system at the ITD Living Lab at the Technical University of Madrid in Spain, and one on the Aquafin campus in Aartselaar, Belgium. Research, led by TU Delft, will be conducted on the technical performance with focus on the treatment performance, recovery efficiencies, and the business case for the different urban applications. Workshops on design guidelines, implementation strategies and dissemination activities will be executed in close collaboration with water managers, landscape architects and end users at the different demonstration sites.

PDEng

The Netherlands and most other countries in the  world are facing serious environmental and societal challenges: sustainable supply of energy and drinking water, wastewater pollution, accessibility of metropolitan areas and enlargement of the rail transport capacity. Climate change, increasing urbanization, a growing demand for high-frequency rail traffic, availability of safe drinking water and the energy transition are today’s challenges in the water and infrastructure sectors.
Unfortunately, many companies still focus on labour flexibility and outsourcing of tasks which has led to a shrinkage of the knowledge level and thus of innovation power. Opportunities for the development of technical experience and new ideas through experience and learning on the job have been greatly reduced and the drift between science and practice becomes greater. Therefore, in both the water and the structural engineering sector, the need for designers who can provide a knowledge impulse to the start of innovations has been increased.
To address the needs for innovation power, the Faculty of Civil Engineering and Geosciences (CGT) of Delft University of Technology has developed a Professional Doctorate in Engineering (PDEng). The PDEng program in Civil and Environmental Engineering is designed in accordance with the guidelines and ambitions of the Dutch technical universities for this type of post master education. It is a two-years program aimed at the creation of systems or products or innovative adoption of current processes to new challenges that match with the needs of the Dutch Civil sector. Participants in the PDEng programme work on an innovation project and follow education to develop the required knowledge and skills for the development and introduction of innovations and new technology.  
The 2019 programme is started in February. Each student is related to a company and works on an actual challenge from the company. The students are their projects are mentioned below:

Awards/ Nominations

Jaap van der Graafprijs awarded to Arnoud de Wilt 




The Jaap van der Graaf Award was presented to Arnoud de Wilt on 11 January 2019, during the 71th Drinking Water and Waste Water Symposium (‘Vakantiecursus’) at Delft University of Technology. This annual prize is given in recognition of the best English-language article about waste water treatment, written by a student or researcher and published during the preceding year. The winning article, by Arnoud de Wilt, was published in the journal Water Research under the title ‘Enhanced pharmaceutical removal from water in a three step bioozone-bio process’.
 
An independent jury considered 59 entries, all of high quality. The names of the three finalists and the overall winner were announced during the Symposium. The jury members based their deliberations on five key criteria: societal relevance, innovation, practicality (with a view to implementation in the short to medium term), scientific content and language. The jury chose the article by Arnoud de Wilt about the removal of pharmaceuticals by a 3 step bio ozone bio process as overall winner.  The article was selected because of the pragmatic approach and well described solutions for one of the largest challenges that the Waterboards are facing at this moment – the ever-increasing presence of pharmaceuticals in waste- and surface water .
 
From the jury report: 'Very interesting, directly applicable, with a clear and comprehensive cost calculation! Although the individual processes are not that innovative, as they are already commercially available, the jury members appreciated the tangible results that show the enhanced performance of using ozone, which is conventionally used as a disinfectant to kill micro-organisms,  in synergy with microbiological treatment for the removal of pharmaceuticals from wastewater.’
 
The Jaap van der Graaf Award is sponsored by consultancy and engineering firm Witteveen+Bos, which created the award in 2009 to mark the retirement of Jaap van der Graaf as Professor of Waste Water Treatment at the Faculty of Civil Engineering at TU Delft.
