CHARACTERISATION AND TREATMENT OF AUTOMOTIVE INDUSTRY WASTEWATER

Abstract

A study on characterisation and treatment of auto components and automotive industry wastewater was undertaken. The wastewater contains heavy metals, oil & grease, organic and inorganic pollutants and also exerts BOD and COD. The wastewater requires chemical treatment comprising of de-emulsification of coolant oil, neutralisation of acid/alkali, precipitation of heavy metals, flocculation, settling followed by pH correction. Depending on the residual BOD/COD after chemical treatment, the wastewater further requires biological treatment.
