1, reverse osmosis equipment
Reverse osmosis is a kind of selective permeability (semi-permeable) membrane function with the pressure as the driving force of the membrane separation technology, when the water inlet end of the system is greater than the osmotic pressure of the solution, water molecules constantly through the membrane, through the production of water flow into the center of the water pipeline, the output of pure water; and after the end of the outflow of the water, such as ionic impurities, organic matter, bacteria, Virus, etc., are retained in the inlet side of the membrane, and then out in the thick water outlet end, so as to achieve the purpose of separation and purification.
Reverse osmosis equipment is the raw water through the quartz sand filter, granular activated carbon filters, precision filters, etc., and then pressurized by the pump, the use of aperture 1/10000μm (equivalent to the size of the Escherichia coli bacteria 1/6000, 1/300 of the virus) of the reverse osmosis membrane (RO membrane), so that a higher concentration of water into a low concentration of water, and at the same time will be industrial pollutants, heavy metals, bacteria, At the same time, industrial pollutants, heavy metals, bacteria, viruses and a large number of impurities mixed into the water are isolated, so as to achieve the drinking provisions of the physical and chemical indicators and health standards, the output of the cleanest and purest water, the human body to replenish high-quality water in a timely manner is the best choice. As the RO reverse osmosis technology to produce water purity is the current human mastery of all water technology in the highest degree of cleanliness almost 100%, so people call this water machine for reverse osmosis water purification machine.
Reverse osmosis equipment application membrane separation technology, can effectively remove charged ions in water, inorganic substances, colloidal particles, bacteria and organic substances. It is the best equipment for high purity water preparation, desalination of brackish water and wastewater treatment process. Widely used in electronics, medicine, food, textile, chemical industry, power generation and other fields.
2, the system composition
Generally includes pretreatment system, reverse osmosis device, post-treatment system, cleaning system and electrical control system.
Pre-treatment system generally includes raw water pump, dosing device, quartz sand filter, activated carbon filter, precision filter and so on. Its main role is to reduce the pollution index of raw water and residual chlorine and other impurities, to achieve the reverse osmosis feed water requirements. Pre-treatment system equipment configuration should be based on the specific conditions of the raw water.
Reverse osmosis device mainly includes multi-stage high-pressure pump, reverse osmosis membrane elements, membrane shell (pressure vessel), bracket and other components. Its main role is to remove impurities in the water, so that the quality of produced water to meet the requirements of use.
The post-treatment system is in the reverse osmosis can not meet the water requirements of the case of increased configuration. Mainly includes negative bed, positive bed, mixed bed, sterilization, ultrafiltration, EDI and so on one or more of the equipment. Post-treatment system can reverse osmosis water quality to better improve the water to meet the requirements of use.
Cleaning system mainly has cleaning water tank, cleaning water pump, precision filter composition. When the reverse osmosis system is contaminated water indicators can not meet the requirements, the need for reverse osmosis cleaning to restore its effectiveness.
Electrical control system is used to control the normal operation of the entire reverse osmosis system. Including instrument panels, control panels, all kinds of electrical protection, electrical control cabinets and so on.
