Performance Evaluation of Polyamide Reverse Osmosis Membrane for Removal of Contaminants in Ground Water Collected from Chandrapur District

This paper examines the influence of different operating parameters such as pressure, temperature, pH on the performance of polyamide reverse osmosis membrane. Varying these parameters, intensive trials were undertaken to study the performance of polyamide Reverse Osmosis (RO) membrane. Water samples for experiment were collected from Moradgaon village of Chandrapur district having high concentrations of fluoride, Total dissolved solids (TDS), sulphate and iron. Results indicate that polyamide reverse osmosis membrane can successfully remove 95 to 98% of fluoride, TDS, sulphate, iron and other ground water contaminants under optimized conditions. Different parameters such as pH, pressure and temperature affects RO membrane efficiency. Thus, proper control of these factors is essential for successful operation and maintenance. RO Membrane generates huge quantity of reject water (i.e.65% -75%), which was further passed through RO membrane to study its reuse potential. The results showed that water received from RO membrane after recycling of membrane reject is within the permissible limits of drinking water as prescribed by Bureau of Indian Standards (BIS).
