Abstract

Study on the factors affecting coagulation and flocculation in treatment of industrial effluents I.G. Bantcheva Department of Chemical Engineering, University of Durban- Westville, South Africa Abstract The introduction of wastewater treatments increases the plant cost; therefor any attempt to improve their efficiency is valuable. The industrial liquid effluents are very difficult to generalize. Their characteristics not only vary with the type of the industry, but also from plant to plant producing same type of end products. Coagulation and flocculation can achieve the effective removal of suspended particles. Operating within the optimum parameters will reduce the cost of treatment and will increase the quality of the water. The objectives of the study were, to compare the effectiveness of different coagulants, to determine their optimum dosage, and the optimum pH. In the present study "Jar Test" was used. Samples from Pulp and Paper, and Textile effluents were used. The fo
