Abstract

Hydrophoric tank has a back-flush filter capable of withstanding an air cushion imposed above it, and the untreated water is fed into the tank below filter level. Back-flushing is effected by forcing the purified water back under pressure through the filter and leading the resulting sludge off from the bottom of the tank.
