Abstract

The dyeing industry is widely recognized as the main source of water contamination. These industries dispose of wastewater in the water bodies along with the solid waste. The physicochemical characteristic of an aquatic body gets affected and estimation of these parameters provides information on water quality and pollution status. Physicochemical parameters like pH, turbidity, chlorides, hardness, total solids, dissolved solids, BOD, COD and sulphates of the surface water samples obtained at different locations near to the Chinnandipalayam Lake, Tirupur were studied to find the influence of the dyeing waste. The water samples collected were treated using natural coagulant and the removal efficiency was studied. The initial pH, Turbidity, COD of the most contaminated sample are 7.95. 21.1 NTU, 666 mg/l respectively. Natural coagulants T.foenum-graecum (Fenugreek), Cicer arietinum (Chickpea), Azadirachta indica (Neem), Moringa Oleifera (Drumstick) and Dolichos lablab (Beans) and also chemical coagulant alum were used in this study and the efficiency of reduction of turbidity using these natural coagulants are 79.6%, 80.1%, 76.8%, 80.6% and 73.0% respectively and of using alum is 95.3%. When using natural coagulant at varying levels, total solids in the sample decreased considerably. At the same time pH and conductivity are not greatly. Moringa Oleifera’s output is greater than that of other four; this depends on the protein content in the natural coagulant. but chemical coagulant has treatment efficiency of 95.3%. Even though alum has more efficiency, natural coagulant is eco-friendly and do not affect the environment after disposing the sludge and also the lake water is being used for the agricultural purpose 80% treatment efficiency can be adopted.
