Innovative technology for treating waste water from slaughterhouses

Waste water from slaughterhouses is difficult to treat because it contains high concentrations of solids and colloidal compounds such as blood, proteins and fats. The waste water is…

Electrochemical treatment processes

Electrochemical treatment processes present various advantages compared to conventional treatment processes. By gaining experience with a single, promising electrochemical method in a relevant water composition (with a focus on its effectiveness and…

Micro- and ultrafiltration in surface water treatment

Surface water utilities in the Netherlands often directly intake river water, which has sometimes passed through a reserve or reservoir. This water needs to be treated in a…

Silicon Carbide (SiC) membranes for innovative applications

The separation of oil from stable oil-in-water emulsions is a challenge. This is especially the case if the permitted limits for oil in water are very low, as…

Biological conversion of micropollutants in drinking water treatment

Various scientific studies have shown that biological processes, such as rapid sand filtration (SF), river-bank filtration, biological granular activated carbon filtration (BAC), and slow sand filtration (SSF), can…

Closing the water cycle in North-Holland

After medicines are used, pharmaceutical residues end up, via the toilet and the wastewater treatment plants (WWTPs), in surface water. Today’s WWTPs do not specifically focus on the removal of micropollutants. Pharmaceuticals…
