Method for reducing chemical oxygen demand of water containing organic material emulsified by a surfactant

A method for reducing the COD of water containing an emulsion of organic material in water. The emulsion contains insoluble organic material and a surfactant. The COD is reduced by mixing a cationic polymer flocculent with the water and maintaining the temperature at from 37 DEG C. to 95 DEG C. for...

Zusammenfassung:	A method for reducing the COD of water containing an emulsion of organic material in water. The emulsion contains insoluble organic material and a surfactant. The COD is reduced by mixing a cationic polymer flocculent with the water and maintaining the temperature at from 37 DEG C. to 95 DEG C. for a sufficient length of time for an organic phase and water with reduced COD to form.
