Abstract
A method for treating and resolving a phosphorus containing oily waste emulsion is described. The treatment uses an emulsion destabilizing cationic polymer of low molecular weight in combination with filter aids to form a coacervate slurry. The coacervate slurry can be optionally treated with either high molecular weight anionic or cationic coagulents, or combination thereof. The suspended solids formed by the above treatments are removed from the slurries and wasted or discarded or incinerated. The remaining liquids may be recycled, reused, or treated as effluent meeting environmental standards.
