Abstract

An improved wastewater purification process, in which lime is added to the water to cause flocculation in one or more flocculation tanks, after which the lumps or clots in a subsequent deposit are separated from the purified water, forming a slime, which comprises returning part of the sludge thus formed to one or more of the flocculation tanks, where it forms a silt zone through which the water being purified is forced to pass, and because the subsequent separation of the lumps by flotation in a flotation tank.
