Water is one of the most important resources for human existence, whether it be for human consumption, agriculture and industry. Ensuring access to safe drinking water is emerging as one of the important challenges of the present century because of steady decrease in the available water resources, industrialization, urbanization, etc. Water in several pockets of the country contains high salinity, and/or harmful contaminants. Desalination of brackish and sea water and water refinement are the major requirements for solving this challenge. Membrane separation processes such as reverse osmosis (RO), nanofiltration (NF) and ultrafiltration (UF) have emerged as an effective solution to produce safe drinking water.
