JFET_V9_N1_A1 Sukanchan Palit Journal on Future Engineering and Technology 2230 – 7184 9 1 1 8 Membrane, Science, Nanofiltration, Reverse Osmosis Environmental issues throughout the world are thought provoking to our mankind. In this age of immense scientific progress and similarly the crisis and catastrophe of the issues of environmental disaster and energy sustainability, the question of novel separation processes comes into the mind’s horizon of a common man as well as a scientist. The alarming question of zero discharge norms is belittling mankind’s progress in science and technology. The world of challenge lies in the field of environmental engineering and the targeted vision of environmental regulations. Standing in such a critical juncture, mankind especially an environmental engineer is more poised towards novel separation processes mainly membrane separation processes. Within this wide and versatile domain of membrane science, nanofiltration has an imminent and far-reaching goal. This review deals with the vast application areas of nanofiltration in the field of desalination and groundwater treatment. The science of nanofiltration connotes to a persuasive definition-the separation of solid wastes whether it is organic or inorganic in view of a greater understanding towards efficiency and effectiveness of the particular membrane separation process. Nanofiltration , reverse osmosis, ultrafiltration and other membrane separation processes today is in the verge of new discoveries and dimensions of invention. Man’s struggle to fetch pure and clean drinking water which is pollution free and remediated has turned out to be one of the greatest social and scientific discoveries of our time. The challenges are immense as well as daunting. Scientific inventions and effective scientific pursuits is bringing our civilization to a new age of scientific validity. Clean water is the boon to a new age of scientific pursuit. The challenge to bring forward the importance of nanofiltration is daunting as well as visionary and it will surely go a long way in opening up new doors of innovation as well as intuition in years to come.
