Due to rapid industrialisation and urbanisation, water pollution by the discharge of the effluent directly into the rivers and water bodies has been increasing day by day. Effluents like paper textile, pharma and leather industries have high polluting parameters like high BOD, COD, total suspended solids, colour, heavy metals etc. Due to high pollution load, effluent treatment has become very capital involvement process. In this studysome coagulants like alum and biological treatment using selected algae were given to industrial effluent to find out reduction in polluting parameters. In the biological treatment bioremediation and treatment with the algae (scenedesmusabundans ) was given. It was observed that various polluting parameters could reduce in the range of 60 to 90 % by using combination of coagulants and biological treatments. Heavy metals also could be reduced significantly in this process.
