Phytoair as a pre-treatment for industrial water at DOW Terneuzen

Chemical giant Dow Benelux in Terneuzen produces basic chemicals and plastics. To reduce the water supply of 14 million m³, the aim is to reuse more purified industrial wastewater. In the spring of 2019 Rietland installed 2 Phyto-air systems of 350 m² on the Dow pilot site. The reed beds serve as a pre-purification for membrane technology. The Phyto-air effluent contains less nutrients and micropollutants. As a result, fewer micro-organisms grow on the membranes, which means that the membrane filtration processes will perform better. This leads to less energy and chemical waste.
