Fresh water factory’s filter plant under investigation
Delfland’s Water Authority is developing a fresh water factory to improve the bathing water quality of the Krabbenplas, a local water body.
Therefore tertiary ozone treatment in combination with continuous sand filtration is projected at wastewater treatment plant De Groote Lucht near Vlaardingen, the Netherlands. The existing continuous sand filter plant, with a design capacity of 1 m3 per second, built in 1998, will be refurbished to meet the present requirements for nitrogen and phosphorus. We are now executing a full inspection of all filter components to upgrade the plant and guarantee operations for the next 10 years.
