pH Control Protects Membranes In Reverse Osmosis

ph control

Reverse osmosis is a technique for removing dissolved solids from filtered raw water. It is used in a variety of industries to condition water for plant use, or as a first step in the demineralization process.

Reverse osmosis works by pressurizing water and forcing it through a semi-permeable membrane, which is permeable to water, but relatively impermeable to dissolved solids. The effectiveness of a reverse osmosis unit is based on its percent efficiency in removing dissolved solids and, generally, the better the quality of raw water, the better the quality of the processed water.
