How does the efficiency of an industrial RO systems vary with the quality of feed water?
When unfamiliar with the technical language used to explain various elements of RO system performance and the connections between these operational variables, reverse osmosis (RO) technology can be difficult to grasp. This blog describes some of these critical concepts and gives a brief review of the variables, i.e feed water quality, that impact the performance of RO membranes. So, let’s get going….. Feed Water Pressure Impact: The water flow and salt rejection of RO membranes are both impacted by feedwater pressure. Water flows through a membrane by osmosis from the diluted side to the concentrated solution side. In order to counteract the osmotic pressure created by the feedwater stream, reverse osmosis technology applies pressure to the stream. The concentrated solution is subjected to pressure that is greater than the osmotic pressure, which causes the water flow to be reversed. The concentrated solution side's purified product water is produced by forcing a portion of t...
