EVALUATION OF BUILDING CONSTRUCTION WATER QUALITY AND REMOVAL OF TOTAL HARDNESS USING LOW COST METHODS

Water is essential for all forms of life, food production and economic development. Only 0.5 % of water is available on earth surface making it more precious commodity on earth. Water covers 70.9 % of the Earth's surface, and is vital for all known forms of life. As Ariyalur is a land of limestone, the cement industries flourishes to maximum resulting in air pollution and water pollution. The Present study is undertaken to investigate extent of pollution, to determine the ground water quality in and around Ariyalur District due to usage of fertilizers and make awareness among the people about the quality of ground water by taking water samples from different locations for analysis. The sample were analyzed for physico–chemical parameters such as pH, EC,TDS, TH, DO, Ca, Mg, BOD COD and NO3. The ground water samples were collected from Ariyalur area and the collected samples were analyzed for major physical and chemical parameters. However the experiments have been performed on the reduction of hardness from synthetic solution and ground water samples using plant materials (Moringa oleifera seeds). The plant materials that have been tested over the years, powder processed from the seeds from Moringa oleifera has been shown to be one of the most effective as a primary coagulant for water treatment.
