ABSTRACT:
Waste water containing synthetic detergents (syndets) such as water soluble sulfonates or ethoxylated alcohols is reclaimed for re-use by emulsifying with a water insoluble, high molecular weight, anionic surface active oil, then breaking the emulsion by conventional physical or chemical methods, thereby producing a coherent floc which occludes the syndet and all insoluble matter suspended in the water, then separating the floc from the purified water in a coherent mass.
