Reverse Osmosis

Overview

What is Reverse Osmosis?

Reverse osmosis is a membrane filtration process that utilizes pressure to reduce dissolved solids in water.

How it Works

Reverse osmosis is a mechanical process in which pressure is applied to a concentrate solution to overcome the osmotic pressure and reverse the direction of the solute flow. Membranes are designed with cross-flow filtration technology. Pressurized solute flows across the surface of a membrane through the feed channel spacer. Approximately 10-15% of the feed water will diffuse through the membrane and flow through the permeate spacer around to the permeate tube. Rejected brine that does not enter the product channel is combined with reject brine from other membranes and can either be treated by a reject-recovery reverse osmosis system or disposed of via other methods.
