The salinity of seawater varies from 3 to 5% depending on different regions and due to this variance it is a challenge to use this abundant water resource for potable or industrial water. CSM’s Seawater RO Membranes, with its high rejection of salts, boron and TDS (more than 10,000 ppm), are able to transform high salinity waters into high grade industrial and potable water safe for human consumption.
