1.The reverse osmosis device is an equipment to purify the saltine water with the action of pressure difference of semi permeable
membrane. It is called reverse osmosis, as it is counter to natural penetration direction. Different materials have different osmotic pressures.
2.The reverse osmosis method to adopt larger osmotic pressures is used to obtain the purpose to separate, extract, purify and condense.
3.More than 97% soluble salts and 99%glues, microbe, particulate and organic substances and etc can be removed with the reverse osmosis.
4.It becomes the most idea equipment for the modem program of pure water, hyper pure water, and airspace water. The remarkable characteristics of the equipment are shown as lower energy consumption, no pollution, simple techniques, high water quality, easy operation and maintenance.
Water treatment process Including:
1. Pre-treatment System.
Pre-treatment system is composed of mechanical filter, active carbon filter, Ion Exchanger and precision filter. The water temperature requires 25±30C.
Flocculator is used for destroying electro-neutral of colloid in water, which ensures raw water can reach to the requirement of Silt Density Index (SDI) ≤ 4. Mechanical filter can remove most of suspension, colloid and grain impurity, which can ensure initial purification of water.
If some of raw water comes from tap water, chlorine content maybe is higher. Low-pressure compound RO membrane has strict limitation to chlorine and organism, which must be ≤0.1mg/1.
Because calcium and magnesium content in raw water is very high, and RO salt-removing rate is about 97%, which may cause deposit of calcium carbonate, magnesium carbonate, bitter salt, etc. on concentrated water side. Deposit adhered on RO membrane surface and may block passage of components and causes pressure difference increase, water output decrease and salt-removing rate decrease, which influence normal running and usage span of RO. So before precision filter, Ion Exchanger is equipped to protect and avoids impurity on RO concentrated water side.
2. 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.
