Desalination equipment for residential use

Due to its very high salt content, seawater cannot be used directly.  two methods are mainly used to desalinate seawater, namely distillation and reverse osmosis. Distillation is mainly used in extra-large seawater desalination and where thermal energy is abundant. The reverse osmosis method is widely used because of its wide application range and high salt rejection rate.
the first step of reverse osmosis method is seawater pretreatment which reduce the turbidity of seawater and prevent the growth of bacteria, algae and other microorganisms. pretreatment is very important to protect reverse osmosis membrane.
the second step is reverse osmosis process. under the
Under the pressure provided by the high pressure pump
The reverse osmosis membrane method first extracts seawater and pretreats it to . Then, it is pressurized by a special high-pressure pump to make seawater enter the reverse osmosis membrane due to high salt content in seawater. Therefore, the seawater reverse osmosis membrane must have high salt rejection, corrosion resistance, high pressure resistance, and anti-pollution characteristics. The salt content of seawater treated by reverse osmosis membrane is greatly reduced, and the TDS content is from 36,000 mg/liter to 200 mg/ l about. The water quality after desalination is even better than tap water, so it can be used by industry, commerce, residents, ships and ships.
