Commercial Seawater Reverse Osmosis Desalination Systems
Seawater commercial water treatment systems Capacity range between 1.4m3/hour to 38m3/day. If you need bigger than this capacity please see our Industrial Seawater Desalination Systems.
All RO Seawater membrane filtration water treatment plants are started from booster pump, it feeds raw water to pretreatment tanks. Depends on capacity pretreatment tank size and numbers can be changed. Because of High TDS (total dissolve solid) and salt water’s corrosion, we are using FRP or Carbon Steel material for pretreatment tanks. Pretreatment consists of Sand Media Filter Tank, Activated Carbon Filter Media Tank and Softener Tank which has ion exchange resin inside, they are very important for commercial RO Desalination Machine.
Pretreatment is used to remove large number of suspended solids, iron, turbidity, unwanted color, unpleasant taste, chlorine, sediment, organic contaminants, odors. In pretreatment we can control the follow manual or automatic for seawater commercial water treatment system.
After pretreatment water goes to cartridge filter housing, we call it as security filter, most of application we are using FRP or PVC Plastic material for cartridge filter housing or Bag Filter Housing. There is 1µm or 5 µm PP filter in cartridge filter housing in Commercial Seawater Reverse Osmosis Desalination System.
After cartridge filter housing, water goes to membrane pressure vessel with High Pressure Pump, you have brand option for High Pressure Pump (Grundfos, Danfoss, CNP or Chunke) and it allows you to adjust your budget. Membrane housing shell inside depends on capacity we have 4040 or 8040 Membranes. Most of our project we are using DOW Filmtec, Toray , Vontron, Hydranautics, LG brand SW RO Membranes.
Membranes, in industrial Brackish Water Desalination Plant, are most important part. They block if parts size bigger than 0.001µm and molecular weight up to 150-250Dalton. It consists of impurities, particles, sugars, proteins, bacteria, dyes, organic and inorganic solids.
Also, RO Seawater Desalination Plant can have chemical dosing at pretreatment or post treatment, like antiscaling (antiscalant), antifouling, pH adjustment, Sterilization & Disinfection chemicals.
