JFET_V10_N1_A1 Sukanchan Palit Journal on Future Engineering and Technology 2230 – 7184 10 1 1 11 Osmosis, Nanofiltration, Advanced Oxidation, Water, Environment The world of Environmental Engineering is moving from one crisis to another. Energy sustainability stands today as a severe and vehement problem of our present-day civilization. Man's civilization is in danger of the future environmental crisis which looms large at the distant horizon of destiny. Provision of drinking water remain as the most difficult problem of Environmental Engineering in our human civilization today. With such an environmental crisis and environmental disaster, the question of novel separation processes such as membrane separation processes stand today as effective procedures in tackling the vicious problem of provision of clean and pure drinking water. The vision for the future is immense, wide and bright. Success and diligence today remain as the key issues of the sound technical know-how of novel separation processes and membrane separation processes. Water crisis is a primordial issue and of serious concern in our present generation and our present day civilization. Issues which are mind-boggling and crucial are groundwater pollution and groundwater remediation. The situation is extremely grave in developing countries throughout the world. Now, in such a critical as well as vexing juncture, the world of challenges needs reassessment and rethinking. Membrane science and membrane separation processes will surely stand towards the imminent crisis of our civilization. Reverse osmosis and nanofiltration stand as future dimensions of scientific research in the future path of innovation and intuition. The presented treatise delineates the immense importance of reverse osmosis and nanofiltration and its impact on global water shortage and the visionary aspects of environmental sustainability.
