Land use seawater desalination equipment

Land use seawater desalination equipment

The composition of onshore seawater desalination equipment mainly includes: water intake system, pre-treatment system, seawater desalination desalination desalination system, energy recovery system, chemical cleaning system, chemical dosing system, as well as device power supply and distribution and automatic control system.

Equipment Process

The seawater is sent to the desalination plant by a deep-water well located by the seaside through a deep-water pump. After adding bactericides and flocculants through a chemical dosing system, it enters the quartz sand and activated carbon filtration system for filtration. The filtered water enters the security filtration system after water quality reduction, pH adjustment, and the addition of scale inhibitors. The filtered low-pressure seawater enters the high-pressure pump for pressurization, and the other enters the pressure exchange energy recovery device. The pressurized seawater is pressurized by the booster pump and mixed with the high-pressure pump effluent to enter the reverse osmosis membrane reactor system. Under the treatment of the membrane stack, a portion of high-pressure seawater passes through the membrane to form fresh water, which is then stored in a fresh water tank after water quality adjustment. The remaining high-pressure concentrated water enters the pressure exchange energy recovery device to recover energy and is discharged.

Equipment Advantages
