Seawater Desalination

Additional Details

Aagam manufactures a range of reverse osmosis seawater desalination systems. The units remove salts from seawater with salinity up to 45,000 ppm TDS water as found in the Mid-East Gulf region and produce water less than 500 ppm TDS for drinking water. Our high purity line of products can also purify seawater down to less than 10 ppm TDS water for boiler feed and other high purity applications.
