Process description: the unit is divided into three treatment systems, namely pretreatment system, ro desalination system, mixed bed fine treatment system, etc. The pretreatment system includes raw water pump, multi-media filter, filter backwashing equipment, etc., which is used to remove suspended solids, colloids, etc. in the water and provide conditions for subsequent desalination. The ro desalination system includes meter filter, ro membrane unit, ro cleaning system and intermediate pool, etc. It is the core system of the device to remove salt from water. The polishing system is mainly composed of mixed bed, regeneration system and neutralization tank. The main function of the polishing system is to ensure the effluent quality index.
