Abstract

A method and an apparatus for purifying raw water. The raw water is pumped into a pressure tank (A). An excess of air and possible chemical agents are added before the tank and are thoroughly mixed into the raw water in a cyclone mixer (B) in order to form a large number of micro bubbles of air in the mixture. The raw water is allowed to oxidize in the pressure tank for a predetermined period of time. Then, the mixture is passed through pipes and pressure reducing valves to nozzles opening into a flotation tank (C). At the pressure reduction, the micro bubbles expand and flotate possible floccules and particles to the surface of the flotation tank, where they are removed, for example by passing over an overflow edge. The flotation tank further comprises several filters having a small exclusion size of about 0.05 microns. Purified water is sucked through the filters by a pump (P2) and expelled.
