The reverse osmosis equipment adopts the most advanced, energy-saving and effective membrane separation technology. The principle of the reverse osmosis equipment is that under the action of the osmotic pressure higher than the solution, other substances cannot pass through the semi-permeable membrane and other substances and water are separated. The pore size of the reverse osmosis membrane is very small, so it can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. in the water. The reverse osmosis equipment can produce pure water and high-purity water to meet the needs of users in different industries and different needs.

1. Pretreatment of reverse osmosis pure water equipment

It consists of multi-media filter, activated carbon filter and automatic water softener.
Multi-media filter: It is composed of automatic control valve, glass fiber reinforced plastic tank and quartz sand with different gradation ratios. It can effectively remove the suspended solids and some colloidal substances in the raw water, and reduce the turbidity in the raw water. And can automatically backwash.
Activated carbon filter: It is composed of automatic control valve, high-quality glass jar and activated carbon of different water purification grades. It can effectively adsorb heavy metals, free chlorine, chloroform and other harmful substances in raw water. And can automatically backwash.
Food-grade water softener: It is composed of automatic control valve, high-quality glass fiber reinforced plastic tank and food-grade resin. The food-grade water softener can effectively remove calcium and magnesium ions from water. So that the reverse osmosis membrane will not affect the service life of the reverse osmosis membrane due to scaling during operation. And can automatically regenerate.

2. Main unit of reverse osmosis pure water equipment

The host of reverse osmosis water purification equipment is mainly composed of security filter, high pressure pump, reverse osmosis membrane and various control and display instruments.

  • Security filter: The security filter is the last protection before the raw water enters the membrane. It can effectively remove substances larger than 5μm leaked from pretreatment. The main purpose is to prevent suspended particles from entering the reverse osmosis membrane element and depositing on the membrane surface to contaminate the membrane element.
  • High-pressure pump: Provide the pressure required for reverse osmosis to ensure the separation of solvent and solute. High pressure pump is one of the key components of reverse osmosis equipment.
  • Reverse osmosis membrane group: The reverse osmosis membrane group is composed of polymeric fibers with a highly ordered matrix structure. Its pore size is 1-10 angstroms, that is, one ten billionth of a meter to one billionth of a meter (equivalent to one six thousandth of the size of E. coli and one three thousandth of the virus), using reverse osmosis membranes It can effectively remove impurities such as dissolved salts, colloids, organics, heavy metals, trihalomethane intermediates, bacteria and microorganisms produced by chlorination in the solvent.
  • Reverse osmosis membrane shell: used to accommodate reverse osmosis membrane elements, pressurized and generate a high-pressure environment for reverse osmosis operation.
  • Flowmeter: pure water flowmeter and concentrated water flowmeter measure the instant flow of RO pure water and concentrated water respectively.
    Pressure gauge: measure the water pressure around the reverse osmosis equipment.
  • Concentrated water regulating valve: used to adjust the operating pressure, pure water and concentrated ratio, and pure water output of RO equipment.
  • Conductivity meter: Monitor the conductivity of reverse osmosis effluent.
  • Low pressure switch: prevent the RO high pressure pump from idling or working under low pressure exceeding the limit.
  • Liquid level controller: Automatically stop or start the reverse osmosis equipment according to the liquid level of the raw water tank and the pure water tank.
  • Electronic control system: including conductivity meter and other instruments and control equipment, is the control center of reverse osmosis equipment.
    The use of reverse osmosis equipment to manufacture pure water and high-purity water needs to be comprehensively designed according to the industry characteristics of each user, equipment water production requirements, and on-site working conditions.
