Making efficient and sustainable water treatment possible

Innovative water treatment technologies

Drinking water treatment is subject to many demands, while circumstances are becoming increasingly complex. KWR’s multifaceted expertise in the field of water treatment technologies addresses a number of the questions confronting the water sector. This helps strengthen the innovativeness, efficiency and sustainability of drinking water or wastewater treatment.

Heavy demands require innovation

While the quality and availability of raw water are declining worldwide, treatment processes are still expected to supply healthy, safe and reliable drinking water, at acceptable cost and energy consumption levels, and with a minimum of waste and by-products. Comparable demands apply to wastewater treatment. In response to such rapidly changing circumstances, the current drinking water treatment technologies have to be adapted. The development and application of innovative processes and concepts for water treatment are needed, so that the water sector can continue supplying water of impeccable quality in a clean environment far into the future.

New technologies and process modelling

KWR disposes of a wide spectrum of possibilities to improve drinking water treatment. Our expertise includes membrane filtration, advanced oxidation, softening, rapid filtration, coagulation, activated carbon filtration and ion exchange. We also develop new techniques, such as eutectic freeze crystallization for the energy-efficient separation of salt and water. KWR plays a pioneering role in the Netherlands in the field of osmotically-driven membrane processes. This is also the case for the development of air/water cleaning to control membrane fouling. With respect to the innovative treatment of wastewater or sludge, KWR develops new knowledge, such as biological sulphate reduction and hydrodynamic cavitation for effective sludge disintegration. Our data-driven models (soft sensors), statistics (data mining and data analytics) and process modelling provide insight into how drinking water treatment processes can be more efficiently organised. Applications can be found in a wide range of drinking water installations: UV or UV/UV/H2O2 installations, ozone installations, softening and flocculation reactors, and service reservoirs.

Innovative, efficient and sustainable

Besides technical solutions, KWR also focuses on other essential elements in the renewal of water treatment processes. Innovation is not only about increased efficiency but also increased sustainability. It encompasses design optimisation and operational management, data processing, soft sensing (simultaneous processing of multiple data) and improved process modelling.
