Medium Sized Fully Automatic Reverse Osmosis System for Reducing Salinity and Improving Water Quality

Product description

Medium – sized fully automatic reverse osmosis systems for reducing salinity and improving water quality are important water – treatment equipment, which are widely used in various fields such as industry and domestic water. The following is a detailed introduction:

System Composition3

• Raw Water Tank (Optional) : Used to store raw water, precipitate large sediment particles and other precipitable substances in the water, and buffer the impact of unstable water pressure in the raw water pipe on the water – treatment system.
• Raw Water Pump : It can keep the water supply pressure of the system constant and ensure a stable water supply.
• Multimedia Filter : It contains multiple – layer filter media, which is mainly used to remove sediment, rust, colloidal substances, suspended solids and other substances with a particle size of more than 20um in the raw water. It can be controlled by a manual valve or an automatic controller for back – flushing and forward – flushing operations.
• Activated Carbon Filter : Usually, nut – shell activated carbon is used. It can adsorb electrolyte ions and organic matter, remove the color and odor of water, reduce the residual chlorine value, and remove pesticide pollutants and trihalomethanes (THM) in water.
• Ion Softening System/Dosing System : In order to prevent the concentration product of calcium carbonate, magnesium carbonate, etc. in the concentrated water side of the reverse osmosis membrane module from exceeding the equilibrium solubility product and precipitating, an ion softening device is used or an appropriate amount of scale inhibitor is added before the water enters the reverse osmosis membrane module.
• Precision Filter : It is equipped with a 5um melt – blown filter element to remove the remaining suspended solids, non – straight – grain substances and colloids in the influent water, preventing impurities larger than 5um from entering the reverse osmosis device and damaging the surface of the membrane.
• High – pressure Pump : It is the core power source of the reverse osmosis system. A high – performance stainless – steel multi – stage centrifugal pump is usually selected, which can provide a stable working pressure (usually between 1.0 and 1.5MPa) for the reverse osmosis membrane.
• Reverse Osmosis Membrane Module : It is the core component of the system, and polyamide composite reverse osmosis membranes are generally used. These membranes have the advantages of high salt rejection rate, strong anti – pollution ability and long service life, which can effectively remove dissolved salts, organic matters, bacteria, viruses and heavy metal ions in water.
• Post – treatment Module (Optional) : According to user needs, modules such as ozone disinfection, ultraviolet sterilization and terminal ultra – filtration can be configured to further improve water quality safety. At the same time, a stainless – steel pure water tank and a constant – pressure water supply pump group can be equipped to achieve continuous and stable pure water supply.

• Working Principle

  The system uses the principle of reverse osmosis. Under the action of high – pressure pump, the raw water is pressurized and passes through the semi – permeable membrane. The semi – permeable membrane has a selective penetration effect, which allows water molecules to pass through, but intercepts most of the solutes such as salts, heavy metals, organic matters and bacteria in the water. In this way, the water passing through the semi – permeable membrane is purified, and the salt content and other impurity contents are significantly reduced, while the concentrated water containing a large number of impurities is discharged, thus achieving the purpose of reducing salinity and improving water quality.

  System Features

  • High Salt Rejection Rate : It can effectively remove more than 90% of dissolved salts in water. The salt rejection rate of a single – stage reverse osmosis system can be as high as more than 97%, and the effluent conductivity can be ≤10μs/cm, which can meet the pure water requirements of most industrial fields.
  • High Degree of Automation : Equipped with a PLC + touch – screen fully automatic control system, it can realize functions such as one – key start, automatic boot flushing, operation, and shutdown protection. It also supports real – time display of operation status, fault alarm, and water quality, which is convenient for operation and management.
  • Energy Conservation and Consumption Reduction : Adopting variable – frequency constant – pressure control technology and high – efficiency energy – saving high – pressure pumps, combined with a reasonable concentrated water recovery scheme, the unit water production energy consumption is low, which can significantly reduce operating costs.
  • Compact Structure : Adopting a modular design concept, the integration is high, and the floor area is small, which is convenient for installation in factory buildings or outdoor containers and is suitable for a variety of installation environments.

  Application Scenarios

  • Industrial Fields : It is widely used in water – using occasions such as small and medium – sized pharmaceutical factories, food processing plants, cosmetics production enterprises, boiler make – up water, laboratory water, and electronic cleaning, which can provide high – quality process water.
  • Domestic Water : It can be used in real – estate properties, communities, etc. to produce drinking pure water, improve the quality of domestic water, and provide residents with safe and healthy drinking water.
  • Desalination of Seawater and Brackish Water : It is applicable to islands, ships, offshore drilling platforms, brackish water areas and other places, which can convert seawater or brackish water into fresh water for domestic and production use.
