With increasing demand for potable water in regions lacking fresh water sources, various potential technologies have been explored for eliminating water shortage. Raw water (from sea, and other water sources) emerged as a potential source for such water deprived areas. The development of raw water reverse osmosis technology proved to be a ground breaking innovation, making it easier to extract pure water from raw water (sea water and Brackish water). Raw water reverse osmosis technology has taken many leaps towards the development of energy efficient and high yielding systems. The reduction in energy consumption, improvement in membrane life and increase in energy recovery emerged as the primary criteria for research in this field. The key objective of the work involves the optimization of the variables involved in the pre-treatment process of different water sources (pond, canal and surface water) reverse osmosis plant which would lead to an increase in the membrane life by reducing solids content of the raw water. Experiments were carried out to ensure maximum total solids reduction and also reduction of different chemical parameters (BOD, TDS and Bacteria). These parameters were found to be desirable for the discharge from the pre-treatment to be fed into the reverse osmosis part of the plant and RO water plant is used drinking purpose and free from contaminants.
