摘要：

Hexavalent chromium is one the most important water pollutants. There are a number of available technologies used for the remediation of chromium, but none of them is applicable to all situations. In this study a hybrid method of coagulation-flocculation uses Moringa oleifera seed coagulant polymer and adsorption-fine filtration with composite of kaolinite clay and sand media for removing chromium ions present in aqueous systems. 98% of chromium ions were removed from the water by this novel technique of coagulation-flocculation and adsorption-filtration process. © 2017, Technoscience Publications.
