Seawater desalination ro plant which is a plant adopts reverse osmosis technology to desalination seawater. Reverse osmosis sea water desalination ro machine composition: water taking system, pretreatment system, Desalination of seawater desalination device, energy recovery system, chemical cleaning part, chemical dosing system and equipment for power distribution and automatic control system.
Seawater desalination ro plant classification: Marine, land use, container type.
Seawater desalination ro plant application: Ship, island, coastal city
Pretreatment system: Pretreatment system includes water supply pump, multi-media filter, precision filter, security filter, the main function is treatment of large particles impurities, residual chlorine and fine particles contained within raw water, to ensure the reverse osmosis system water inlet quality.
Reverse osmosis system: Reverse osmosis system including: high-pressure pump, RO reverse osmosis membrane components, pressure regulator, cleaning tank, the major function: further treat the after pretreatment water to fresh water.
Seawater desalination ro plant treatment working principle: Seawater from water supply pump into pretreatment system, after adding fungicides and flocculants through chemical dosing system into the quartz sand and activated carbon filtration system filtration.
After pretreatment system seawater then into high-pressure pump, under the action of high-pressure pump, via high desalination rate roll-type membrane, through control valve to increase the pressure, so that part of pure water in the sea water go through membrane into porous collection tube, pipe out of the equipment by means of soft tube, while salt is blocked in the membrane surface together with most of the seawater discharge from plant.
Filtered water after water quality reduction, PH adjustment and after adding inhibitor into the 5um security filter system, filtered low-pressure seawater all the way into high-pressure pump for pressuring, the other way into the pressure exchange energy recovery device.
The pressurized seawater is pressurized with a booster pump and mixed with water come out from high pressure pump enter into reverse osmosis membrane stack system. Under the treatment of membrane stack, some water through the membrane become fresh water, after water quality adjustment into the fresh water tank for storage. The rest of the high pressure concentrated water enters pressure exchange energy recovery system, after recovering the energy then discharge.
