Core Technical Principle
It operates based on the reverse osmosis principle, with a semi – permeable membrane as the core component. Under the action of pressure higher than the solution’s osmotic pressure, water molecules selectively pass through the semi – permeable membrane from the high – concentration solution side to the low – concentration solution side, while impurities such as dissolved salts, colloids, microorganisms, and organic matters in the solution are 截留 on the high – pressure side of the semi – permeable membrane, thus achieving the efficient separation of water and impurities.
Key Components
- Pretreatment System: It is crucial to ensure the stable operation and service life of the reverse osmosis membrane. It generally includes a mechanical filter to remove large – particle suspended solids and sediment, an activated carbon filter to adsorb residual chlorine, color, odor, and some small – molecule organic matters, and a scale inhibitor dosing device to prevent scale formation on the membrane surface.
- Reverse Osmosis System: This is the core part, composed of multiple reverse osmosis membrane modules connected in series or parallel. The aperture of the reverse osmosis membrane is extremely small, about 0.0001 microns, which can effectively intercept most dissolved salts, bacteria, viruses, colloids, and other impurities. Under the pressure drive of the high – pressure pump, the raw water flows on the membrane surface, and water molecules pass through the membrane to enter the product water side, while impurities form concentrated water and are discharged.
- Post – treatment System: After reverse osmosis treatment, the water quality has been greatly improved, but it may still need further treatment to meet specific reuse requirements. It usually includes a pH adjustment device to adjust the pH value of the reclaimed water and a sterilization and disinfection device, such as an ultraviolet sterilizer or a chlorine dioxide generator, to kill residual microorganisms.
Application Advantages
- Excellent Product Water Quality: It can effectively remove more than 98% of dissolved salts, more than 99% of bacteria and viruses, and almost all colloids and organic matters in the raw water. The product water quality is stable and has a high purity, which can meet a variety of strict reuse scenarios, such as the preparation of ultra – pure water in the electronic chip manufacturing industry and the process water in high – end chemical production.
- Wide Adaptability to Water Quality: Whether it is the secondary effluent of urban domestic sewage after preliminary treatment or the complex organic wastewater generated in industrial production, after appropriate pretreatment, the reverse osmosis reclaimed water reuse equipment can deeply treat it, showing strong water quality adaptability.
- Outstanding Water – saving and Pollution – reduction Benefits: By converting sewage into reusable reclaimed water, it greatly reduces the intake of fresh water resources and relieves the pressure of water shortage. At the same time, it reduces the total amount of sewage discharge and the pollution load on natural water bodies.
Application Scenarios
- Industrial Production: In industries such as electronics, pharmaceuticals, chemicals, and electricity, the treated reclaimed water can be reused for process water, such as the cleaning water in electronic chip manufacturing, the liquid – preparation water in the pharmaceutical industry, and the reaction water in chemical production.
- Urban Miscellaneous Use: It can be used for urban greening irrigation, road flushing, landscape water replenishment, toilet flushing, etc., effectively saving the water resources of the urban water supply system.
- Seawater Desalination: In coastal areas, through the reverse osmosis treatment of seawater, fresh water that meets the living drinking water or industrial water standard can be produced.
Development Trends
With the progress of membrane material technology and the optimization of equipment manufacturing technology, reverse osmosis reclaimed water reuse equipment is developing in the direction of low energy consumption, high anti – pollution, and intelligence. The research and development of new anti – pollution membranes effectively extends the service life of membrane modules and reduces maintenance costs. The application of energy recovery devices significantly reduces the energy consumption of the system, and the integration of the Internet of Things technology and big data analysis realizes the remote monitoring of equipment operation status and fault early warning.
