Abstract

The treatment of industrial wastewater technology is varies from simpler technology to the more advanced technology. This study was based on evaluation, of the possibility of applying saponification/coagulation followed by sedimentation to reduce oils content from refinery plants oily wastewaters. Sodium hydroxide solution (strong base) was used as saponifier for oily wastewater. Ferrous sulfate; ferric chloride and alum were tested by jar test analysis as coagulants to determine the best removal% of COD. The results show that sodium hydroxide, 1 molar concentration; with dosage 10 ml was more efficient for saponification. The comparison between the three different types of treatments methods (sponification followed by sedimentation, sponification followed by cogulation with sedimentation and cogulation followed by sedimentation) indicated that ferric chloride with 40 mg/l dosage is more efficient for coagulation and sedimentation treatment after saponification of refinery plants wastewaters & give a removal efficiency of about 84%.
