Abstract - Most of the industries use a large amount of water for their chemical processes and for steam generation. Surface waters, have both dissolved and suspended particles. Coagulation processes is used to separate the suspended solids. The suspended particles are different depending on their source, composition, charge, particle size, shape, and density. A right application of coagulation processes and selection of the coagulants is based upon the interaction among these factors. The small particles are stabilised by the action of physical forces on the particles themselves. One of the forces playing a dominant role in stabilisation results from the surface charge present on the particles. Suspended particles in water possess a charge and, if they have the same type of surface charge, they repel each other as they come very close together. Therefore, they remain in suspension instead of join together and settle down. The present study aims to treat a sample of industrial water(river source) for the removal of impurities by the addition of coagulant Alum.. The treatment efficiencies of coagulant at different levels have been compared for maximum removal of impurities.
