Explanation
Reverse Osmosis is a type of (B) Cross flow filtration system.
In reverse osmosis, a cross flow filtration system is used, where the feed water flows parallel to the membrane surface, creating two streams: the permeate (treated water) that passes through the membrane and the concentrate (reject stream) that carries the rejected solutes away from the membrane. This cross flow configuration helps to reduce fouling and maintain the efficiency of the membrane during the filtration process. Reverse osmosis is widely used for water purification, desalination, and various industrial applications.
