Water treatment for Berlin airport

Berlin Brandenburg Airport is an international airport close to Berlin. The airport is part of a plan to keep up with required future passenger capacity in Berlin airport, which is the third largest airport in Germany. The new airport is a large expansion of the existing airport Berlin Schönefeld international.

SILHORKO-EUROWATER has delivered water treatment for the airport through E.DIS AG. The city-water is demineralized by two parallel reverse osmosis systems (RO). To avoid hardness precipitation antiscalant is added before RO.

Different water qualities are used as make-up water for the district heating network and the cooling towers. The circulation water of these networks is treated with chemicals and a partial flow is filtered.
