RO System
RO system is composed of high-pressure pump, RO system and chemical cleaning device.
During running, RO membrane may form some deposit and chemical cleaning device is equipped for periodical cleaning to ensure stable running of RO system. This system configures with membrane compounds and high-pressure pump.
High-pressure pump is the power source of RO system. To RO system on sound running condition, high-pressure pump equips inlet/outlet pressure switch. When inlet pressure is less than set value (water lack P≤0.05Mpa) or outlet pressure is higher than set value, pressure switch send signal to PLC programming system and high-pressure pump and RO system will stop in avoidance of destroying to RO membrane because of water pressure.
RO system pressure control and automatic cleaning are controlled by PLC. RO system can wash surface of RO membrane by low-pressure timely and periodically.
