Dunea happy with innovative rinse water processing

Dutch dunes play an important role in producing drinking water. Dunea extracts water from the dunes and processes it into drinking water that it supplies to 1.3 million people in the west of the province South Holland. In addition to supplying high quality drinking water, Dunea wants to reduce its environmental impact to the minimum. 

In the old situation, the rinse water (the residual water from the slow sand filter washing process used when treating the water from the dunes) was routed to settling ponds  where suspended solids could settle out. Using the new technology, the rinse water runs over special rapid sand filters, allowing the rinse water to be reused. This means that, thanks to the immediate recirculation, not only the rinse water is treated more effectively, but substantial financial savings are also realised. Moreover, the drinking water production capacity will increase, which will improve supply reliability and process continuity. Attractive additional advantages.

The entire process will occur in the prefilter building in Katwijk, which will be renovated by the primary contractor K_Dekker bouw & infra b.v.. The renovation of this national monument, which is subject to statutory maintenance obligations, should be completed in mid-2021. When it is completed, the newly developed filter installation, consisting of filter tanks and a UV installation, will be installed in a ‘box construction’ by Logisticon Water Treatment.
