Review of Reverse Osmosis as Green Technology against Water Supply: Challenges and the way Forward

Abstract

Contaminated water can be treated and be re-used but where portable water supply is not available, implementation of reverse osmosis technology is capable of increasing the volume of water supply. This paper reviewed the technology behind reverse osmosis, their proportional utilization, methods classification, expected technical problems and solutions that are connected with its operation. Desalination is admitted as one of the major application areas of reverse osmosis program.  The review acknowledges fouling, scale formation and corrosion as the major challenges that can hinder the operation of reverse osmosis plants and recommended precautional methods during design, testing and implementation of reverse osmosis plants.
