Drinking water companies: drinking water sources under increasing pressure

Mon 16 September 2019

The report from the KWR Research Institute, published last week, shows that Dutch drinking water sources are under increasing pressure. "It is two to twelve for Dutch drinking water sources", said Vewin chairman Peter van der Velden, who handed over the report to Cora van Nieuwenhuizen, Minister of Infrastructure and Water Management.

The production of drinking water will require an increasing effort if no improvements are made, warn the drinking water companies. They are concerned about the increase in existing and new threats. The drinking water companies welcome the "acceleration tables" that are set up by the Minister of Infrastructure and Water management in 2018, with the aim of speeding up the improvement of water quality.

Climate change, among other things, has a negative impact on the quality of drinking water sources, due to the concentrations of contaminants that can increase at low river discharges. Furthermore, recent studies have shown that concentrations of natural organic material (NOM) in surface water are becoming increasingly higher. All this demands more from drinking water treatment. One way to make the purifications work more efficiently is to remove natural organic material. This can be done in various ways, but ion exchange seems to be the most effective.

Are you involved in drinking water treatment? On 4 and 5 November you will learn all about the latest developments and innovations concerning NOM characterization and removal in the new international course Natural organic matter in drinking water, following the European DOC2C's research project. You will learn more about the behavior of NOM in natural water, the influence of NOM on treatment processes, the principles of NOM removal processes (such as ion exchange and coagulation) and the possibilities and challenges of brine treatment (and reuse). In addition, the course can also be supplemented with a visit to Aquatech and an extra course day dedicated to feasibility studies of the DOC2C research project at PWNT Andijk.
