18 ABSTRACT The present invention is a process for treatment of waste water streams having a sodium sulfate content of above 20 percent. The process is useful for treating waste water generated in the production of polyethyleneimine and cyclohexanone. The process includes the steps of removing sodium sulfate from waste water by the addition of organic solvent. The waste water having reduced sodium sulfate content is then subjected to biological treatment with activated sludge. First the waste water is subjected to pre-treatment. Pre-treated waste water is combined other waste water and treated by denitrification and nitrification.
