ABSTRACT:
A filter for disinfecting non-potable water disposed in line in a water delivery pipe such filter having a plurality of aligned chambers is disclosed. The first chamber contains biocidal resin which imparts a biocide to the water as it passes therethrough. The water then passes through a turbulating disk to an extended contact time chamber 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 containing media which removes the biocide from the water. The water then passes through a chamber containing bacteriostatic media which acts to prevent back contamination from the effluent end of the filter. The water then passes through a 3-micron screen which acts to retain protozoan cysts within the filter as the water passes on in the water delivery pipe.
