Additional Information:	<p align="justify">Potable water can be drawn from surface as well as ground water. Ground water is in a more pure form than surface water and hence requires less treatment to get good quality water. But due to the depletion of the water table,usage of surface water has gained its importance. To meet the stringent water regulations surface water needs appropriate treatment due to the constant contamination of their sources by industrial and agricultural pollutants. Thereby the need of advanced treatments like ozonation, activated carbon, membrane processes, deionization etc is aroused. In this context, membrane processes have gained importance due to their excellent separation capabilities. Many studies have been carried out using membranes either alone or in conjunction with other traditional processes like sand filtration, carbon filtration, chlorination etc. The flux rate in membrane systems was found to decrease due to their fouling tendency. The fouling tendency was found to decrease when integrated membrane systems are used. RO & NF showed good retention of micro pollutants and other impurities but they were not cost effective. Thus low pressure membrane processes like UF and MF in conjugation with traditional processes have gained an upper hand which also showed better retention of micro pollutants and other specific impurities apart from being cost effective. In developed countries the cost effectiveness between traditional and membranes processes was proven to be comparable, but in developing countries usage of membrane processes is still primitive due to their high energy requirement and high capital cost. Thereby extensive research is needed to implement membrane processes in a cost effective manner which also assures that water is not dangerous to sip.</p>
