Abstract
Municipal wastewater treatment and its properdisposal are major problems being faced by all the municipalities of growing cities throughout the country. The high price of treatment plant has forced many of the municipalities to discharge domestic waste water without any treatment. Remediation of nutrients from wastewater is an emergingtechnique of environmental biotechnology in which various living organisms used for environmental clean up and pollution control. The objectives of the present study was to evaluate the potential of three different aquatic macrophytes for treatment of municipal waste water and are recommended to its use for gardening and irrigation purposes after dilution. Maximum fresh matter and dry matter yield at 7, 15 and 30 days growth of Cladophora and Lemna was observed at 60 percent level of municipal waste water and of Azolla was observed at 40 percent level of municipal waste water. Maximumvalues for chlorophyll, ascorbic acid, catalase and peroxidase activities was observed with the range of 20 to 60 percent level of municipal waste water at 7, 15 and 30 days growth and heavy metals Iron, Manganese, Zinc and Chromium accumulationwas observed at 30 days growth of Cladophora, Azolla and Lemna plants.
