ABSTRACT:
This invention is directed to an improved process for clarifying a waste water stream containing waste synthetic polymeric material in latex form. The process comprises treating the waste water stream in sequence with calcium chloride and a cationic flocculant, calcium, potassium or sodium hydroxide, and an anionic flocculant. The aggregated polymeric material which results is then separated from the waste water and an essentially clear waste water stream is thereby provided.
