  • Seawater Reverse Osmosis Systems SWRO - Pure

    Does reverse osmosis remove salt from seawater? Yes, semipermeable membranes enable the feed water to pass through it at a much higher volume than dissolved salts. Reverse osmosis systems work by applying pressure as freshwater streams through its membranes to filter out the concentrated saline in the feed water, as well as minerals and pollutants. These unwanted impurities are either flushed away, …
