Water desalination can be performed by using reverse osmosis water treatment systems. This is the most economical way for desalination of sea and brackish water today. AXEON Water Technologies designs, engineers and manufactures a variety of reverse osmosis water treatment systems. The main component of reverse osmosis water treatment systems is the reverse osmosis membrane. To protect the reverse osmosis system from dangerous impurities contained in feed water, the system is equipped with the appropriate pretreatment components, such as sediment filters and anti-scalant dosing systems. After the reverse osmosis membrane, the product water usually has a low pH. To adjust the pH, the water passes through a pH adjustment stage in the system. Then the treated water goes into a storage tank. The last stage consists of disinfecting, re-pressurizing and distributing the water for use.
