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 Reverse Osmosis (RO) membrane. Water samples for experiment were collected from Moradgaon village in Chandrapur district with high fluoride, TDS, sulphate and iron concentrations. Removal efficiency of contaminants due to the effect of different operating parameters of RO membrane was studied in detail. Results indicate that polyamide reverse osmosis membrane can successfully remove 95 to 98% of fluoride, TDS, sulphate, iron and ground water contaminants. 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 reject water is within BIS limit of drinking water.
