Operating methods of seawater desalination equipment

Due to its high salt content, seawater cannot be directly used. Two main methods are used to desalinate seawater, namely distillation and reverse osmosis.

Distillation method

Distillation method is mainly used for large-scale seawater desalination treatment and places with abundant heat energy. The reverse osmosis membrane method is widely used due to its wide applicability and high desalination rate. The reverse osmosis membrane method first extracts seawater for preliminary treatment to reduce seawater turbidity and prevent the growth of bacteria, algae, and other microorganisms. Then, a special high-pressure pump is used to pressurize the seawater to enter the reverse osmosis membrane. Due to the high salt content of seawater, the seawater reverse osmosis membrane must have high desalination rate, corrosion resistance, high pressure resistance, and pollution resistance. After being treated with the reverse osmosis membrane, the salt content of the seawater is greatly reduced, The TDS content has increased from 36000 mg/L to around 200 mg/L. The water quality after desalination is even better than tap water, which can be used by industry, commerce, residents, ships, and ships.

Reverse osmosis method

The seawater has a high salt content, high hardness, and is highly corrosive to equipment. Moreover, the seasonal changes in water temperature make the reverse osmosis seawater desalination system much more complex than conventional brackish water desalination systems, and the engineering investment and energy consumption are also much higher. Therefore, it is particularly important to reduce engineering investment and energy consumption through meticulous process design and reasonable equipment configuration, thereby reducing the unit water production cost and ensuring the stable operation of the system.

The above is the operation method of seawater desalination equipment that Hongjie Water brings to everyone. I hope it can help you!
