Biodegradation of domestic effluent using different solvent extracts of Murraya koenigii


Many water bodies are polluted by the harmful chemicals present in industrial and domestic effluents which is untreated and released in to them. In this work, the fresh leaf powder extracts of Murraya koenigii was treated with domestic effluents at acidic pH for three days and their effects were studied. Four different solvents were used for extracting the plant constituents such as benzene, ethanol, acetone and propane-2-ol. Among two different volumes (5ml and 10ml) of extract, waste water treated with 10ml extract showed higher reduction of hardness, TDS, sulphate and nitrate. Hardness of the water was highly reduced by ethanolic extract (21mg/l). The extract of acetone reduced more TDS (15mg/l). Both benzene, acetone and ethanolic extracts showed more reduction in nitrate levels (6.1mg/l). An enormous reduction in sulphur was found in benzene extract (3mg/l).
