In drinking water, when the chloride over a preaching range (250mg/L), as a brackish water. Because the chloride is not used for other substances, can use some filter removed, while the removal process of chloride by the reverse osmosis treatment. The technology of water treatment technology developed in recent years, especially suitable for the treatment of chloride in water.

One: distillation

Distillation is to brackish water or seawater is heated to boiling evaporation, then the process steam is condensed into fresh water. Distillation is the earliest use of brackish water desalination method, its main advantages are simple structure, easy operation, good quality of the fresh water. Distillation method has many kinds, such as multi effect evaporation, multi-stage flash, pressure steam distillation, membrane distillation etc..

Two: electrodialysis method

Ion exchange membrane electrodialysis method using in the electric field, the anion and cation separation in brine, so that the concentration of salt fresh water chamber to reduce and get a membrane separation technology of freshwater. Electrodialysis apparatus is directed migration under the action of electric field and ion, by selecting the permeability of ion exchange membrane salt to reach out. Electrodialysis brackish water desalination technology is mature, has the advantages of simple process, high desalination rate, water of low cost and convenient operation, no environmental pollution and other major advantages, but the existence of water quality requirements are more stringent, the need for pretreatment of raw water and other shortcomings. In twentieth Century 50, the United States, Britain began to apply this method to the brackish water desalination, China in twentieth Century 80 time this method has been applied in brackish water desalination, industrial pure water and ultrapure water production.

Three: the reverse osmosis method

Reverse osmosis is the concentrated solution side plus than natural infiltration higher pressure, torsion natural permeability direction, the ions in solution and pressure to the other side of a semipermeable membrane, the process and the nature of the normal penetration of the opposite, so called "reverse osmosis", such a device is called reverse osmosis device. Reverse osmosis brackish water desalination method can be removed from the water more than 90% soluble salts and colloid microorganism above 99% and organic matter etc.. Compared with other water treatment method has no phase change, room temperature operation, simple equipment, high efficiency, less land occupation, convenient operation, less energy consumption, to adapt to a wide range of advantages, high degree of automation and good water quality etc.. Our company produces the brackish water desalination equipment suitable for high salt area and inwelling region, uses the high quality reverse osmosis membrane element, pressure vessel, pressure pump, with reasonable pretreatment equipment, can effectively remove the harmful components in water and inorganic salt, heavy metal ions, organic matter, bacteria and germs, pain brackish water desalination water quality meet the national drinking water standard. Detailed analysis and special design according to the water quality of local customers, and strive to achieve efficient and durable, and the desalination water quality fully meet the national standard for drinking water quality (GB5749-85), completely solve the problem of drinking water in water shortage area. Because the underground water quality in different regions, the user can provide the best quality with local analysis report, to ensure that the design the most reasonable and economic configuration, to achieve the best effect.
