Brackish Water

In some saline and alkaline areas and sea water intrusion regions, inorganic salt and heavy metal contents in water are relatively high. Brackish water desalination equipment, quality pressure vessels, high-pressure pumps and together with reasonable pretreatment equipment can effectively remove inorganic salt, heavy metal ions, organisms, bacterium and viruses in water and transfer brackish water into quality water meeting national requirements for drinking water.

Antisludging agent in metering pump can postpone salt crystallization and precipitation. The method can also be adopted for preventing scaling pollution of reverse osmosis. However, as calcium and magnesium ions remain in water, calcium and magnesium ions in water after reverse osmosis are more than that of softening, while medication and scale inhibition can easily realize automatic control, as well as lower equipment cost. In addition, using antisluding agent can reduce silicon precipitation, which cannot be realized by softening. It is thus suitable for underground water treatment. Cost of softening facilities is proportional to the flow, while the cost of antisludging agent feeding facility is not closely related with flow. Thus, double RO and ware system usually adopt antisludging agent feeding system. Water softener or metering pump can be properly selected based on water quality; or neither of the two is required for use if the water quality is good.
