CONTINUOUS FLOW WATER-PURIFYING DEVICE

摘要

A filter (10) for disinfecting non-potable water disposed in line in a water delivery pipe, such filter (10) having a plurality of aligned chambers is disclosed. The first chamber (12) contains biocidal resin which imparts a biocide to the water as it passes therethrough. The water then passes through a turbulating disk (14) to an extended contact chamber (16) of a selected cubic volume to allow further contact time between the biocide and any microorganisms in the water. The water then passes through a biocide removal chamber (20) containing media which removes the biocide from the water. The water then passes through a chamber (24) which acts to prevent back contamination from the effluent end of the filter (10). The water then passes through a 3-micron screen (26) which acts to retain protozoan cysts within the filter as the water passes on in the water delivery pipe.
