Treatment of Municipal Waste Water Using Naturally Available Coagulant

This paper reviews an attempt to evaluate the comparative effectiveness of natural coagulants such as tamarindus indica seed powder and carica papaya seed powder for the treatment of Municipal waste water. This study mainly focused on turbidity removal, Total dissolved solids, Chemical oxygen demand, total suspended solids from Municipal waste water. The main aim of the environmental agencies and government are to seek ways to minimize the considerable increase in the rate of water pollution due to urbanization and industrialization. Coagulation and flocculation using chemicals are also adopted for treatment process. But due to high cost of chemical coagulants, this can be replaced by natural coagulants. This experiment was conducted at room temperature without adjusting the PH. Various conditions such as coagulant dose, stirring time and settling time is varied and its optimum values are obtained. Results show the reduction in turbidity, TDS, TSS, Ph, TS and COD by using natural coagulants.
