ViviMag project nominated

The Wetsus/TU Delft ViviMag project has been nominated for the Dutch Water Innovation Prize, awarded annually by the Association of Dutch Water Authorities. The 3 nominees have been announced today at the Innovation Expo. The award ceremony will be held on November 29.

ViviMag develops and is scaling up a magnetic separation process to recover the insoluble iron phosphate mineral vivianite from the Sewage Treatment Plants (STPs) that rely on chemical Phosphate removal. The separation process is applied on sewage sludge after anaerobic digestion. Anaerobic digestion reduces the sludge volume and recovers energy in the form of biogas. During anaerobic digestion Fe(III) is reduced to Fe(II), which results in vivianite formation. For this project, a consortium has been formed by EIT RawMaterials, Brabantse Delta, STOWA, Waterschapsbedrijf Limburg, Kemira Oyj, Outotec GmbH & Co. KG, TU Delft, ICL Fertilizers Europe C.V. and Wetsus.

Successful first European Water Technology Week

The first edition of the European Water Technology Week, held from September 22 to 27, attracted 1000 individual participants. Most guests attended more than one day, so every day of the congress week we welcomed over 500 people. The EWTW included the Wetsus Congress, with an extensive scientific program, and WaterLink by WaterAlliance, focusing on business in water technology. A group of international secondary school students was busy at the EIT Raw Materials Science Fair at Wetsus and the Province of Fryslan held the IJsselmeersummit. The water tech tours on Thursday took a lot of people to visit water tech spots in the area, and also part of the program were the Selenium Summit and the kick off of the European project iWATERMAP. On top of this, the open door day, the WaterCampus Experience Day, attracted 3000 visitors. We thank all our visitors, speakers and exhibitors for coming to Leeuwarden and participating in EWTW. The next European Water Technology Week will be held in 2020, in the week starting September 21. More information.

Next year, 2019, we hope to welcome you at the Wetsus Congress, October 7 and 8. You can already save the date!

Dr. Joop Kruithof Knight in the Order of the Netherlands Lion

During the Wetsus Congress part of the EWTW, there was a special moment for dr. Joop Kruithof. Mona Keijzer, State Secretary of Economic Affairs and Climate Policy, appointed Joop Kruithof Knight in the Order of the Netherlands Lion for his lifelong contribution to water research. Despite being retired, Joop remains very active internationally. He stimulates water technology innovation in many ways and successfully coaches water professionals. He is connected to Wetsus as member of the Program Board. We of course sincerely congratulate Joop with this big honor!

Two Marcel Mulder Awards in 2018

During the Wetsus Congress part of the EWTW 2018, the annual Marcel Mulder Award Ceremony was one the highlights. This year, two Wetsus PhD researchers were awarded the prize: Jaap Dijkshoorn and Victor Ajao.

Victor focusses on natural flocculants. Flocculants are valuable chemicals that are widely used in water based industries and water treatment.
The process of Victor aims at producing flocculants that are biodegradable. This is very important for reusing sludge in natural applications. His flocculants are produced from waste. This shows the circular economy in action; transforming waste into high value products. Victor also contributed to the George Barley Water Prize, a competition of which Wetsus already won 2 stages.

Jaap is working on the removal of small particles from water. A filter with small holes could be used for this, but this gets easily clogged and making frequent cleaning necessary. He came up with an alternative: a microfluidic device that is based on production technology derived from electronic chips, but realized that the production costs of these devices are too high, hampering application. He therefore came with the idea to apply the principles of the costly microfluidic device to currently available cheap filters. He developed a new type of filter which has many advantages over current filters. The idea showed to be novel and a patent is applied for.

Congratulations to both of you!

First Soil Food Week

Next week the first Soil Food Week will be held, a week about topics related to soil, food and health. Wetsus is involved in the program. Highlights from the program are the Symposium Symphony of Soils and an international Seminar Organic Farming and our Future Food System.

The Symphony of Soil symposium addresses the vitality of our soil related to our future. Wetsus and Wetterskip Fryslan organize a workshop: Soil-Water interactions: views on the role of Soil Organic Matter. Soil Organic Matter is regarded as the key to many different processes in soil, including water retention and nutrient control. Do we all share this view? And what does this promises us if we try to improve both SOM Quantity and Quality? Will it provide us with dry feet, reduce effects of the droughts we experienced last summer, improve crop growth? What are the boundaries to these expectations?
