Abstract
Waste water is reclaimed for re-use by emulsifying with a water insoluble (or oil soluble), high molecular weight, anionic surface active oil, then breaking the emulsion by physical or chemical methods, thereby producing a coherent floc which occludes insoluble matter suspended in the water, then separating the floc from the purified water in a coherent mass.
