Sea Desalting

   With the decreasing fresh water resources, water has become very important natural resource while insufficient water resource has increasingly attracted people’s concern. Sea water desalting equipment transfers inedible sea water into fresh water, greatly saving fresh water resources and bringing hope to the prospect of water resources. Sea water cannot be drunk directly for its high salt content. Currently, two methods are mainly adopted for desalting sea water, namely distillation and RO method. The former is mainly used in extremely large sea water desalting and places with abundant thermal energy. Sea water desalting equipment overcomes the traditional problem with its new technology.
   The equipment mainly adopts RO method which can be divided into the following parts: sea water tank → medication tank → raw water pump → sand filter → carbon filter → precise filter → high-pressure pump → energy recollection device → reverse osmosis module → sterilizer → fresh water tank → water discharge. Some auxiliary devices may be added to the sea water desalting equipment based on the location, water quality and application of desalted water to meet the requirements of customers. At present, the mature technology of RO membrane and film element and improved performance have greatly dropped down the prices and thus led to lower costs; low energy consumption of the equipment is conducive to energy conservation and water preparation cost reduction; membrane-method sea water desalting a of unit combination and the construction scale can be enlarged gradually, making it easy to promote application. 
   Sea water desalting equipment is applicable to cargo ships, oil tankers, offshore drilling platforms, islands, stations and coastal cities lacking for fresh water. It can effectively remove inorganic salts, heavy metal ions, organic bacterium and viruses and other hazardous elements in sea water.
