Ground water contains mostly unacceptably high levels of dissolved salts and minerals. Depending on the application, brackish water TDS is in the range of 1,000 to 10,000 ppm and high brackish TDS varies from 10,000 to 15,000 ppm. Generally, water that contains TDS of above 15,000 ppm is considered as a Seawater application. Our Seawater RO systems are designed to treat raw water TDS up to 45,000 ppm. Capacities ranging from 5 m3/day to 4000 m3/day. 1.Direct Flow RO System AQUA CUBE BOX - All in one system, Streamline, Digit flow monitor, Easy replacement Compact or Stainless Steel Case 2.Aquarium RO, Clean Water for Fish AQUARIUM RO KIT 3 Stage Aquarium RO unit Aquarium RO unit 3.RO Element & UF Element 4.Compact Types 150Gpd-400Gpd 5.Commercial Type 300gpd,800gpd,1000gpd,1500gpd ,3000gpd,4500gpd,6000gpd to 14000gpd 6.Wide RO 1000gpd to 10000gpd 7.Horizontal RO System 6000gpd to 60000gpd 8.UF Filtration & Sea Water RO System 9.Fancy Filtration - Un, Deux, Trois...
