Water Desalination by Reverse Osmosis

Brackish and sea water contain a high level of dissolved salts, with TDS from 1.500 to 47.000 mg/1. After a suitable pre-treatment salty water can be desalinated by UNIHA reverse osmosis (RO) Systems. Salty water is pumped under high pressure through a plastic mem-brane, the water (solvent) passes through the membrane and the dis-solved salts are retained by reason of their different molecular structure. These membranes pass relatively pure water (permeate) and retain concentrated salty water (concentrate). By using different types of membranes and based on our experienced calculations, we can achieve any requested treated water quality for potable/drinking and industrial purposes.UNIHA scope of supply for water treatment includes both semi auto-matically and fully automatically controlled processes.
