Product Introduction
- Relying on the principle of reverse osmosis of semi – permeable membranes, it can effectively intercept impurities such as inorganic salts, organic matters, bacteria, and viruses in water, achieving deep purification of water quality.
- The desalination rate of the equipment is as high as over 98%, and it can produce ultra – pure water that meets the strict industry standards of electronics, pharmaceuticals, chemicals, etc.
- With a modular design, it can be flexibly combined according to different water production requirements, adapting to various production scales.
Working Process
- Raw Water Pretreatment: The raw water passes through pretreatment equipment such as multi – media filters, activated carbon filters, and precision filters in sequence to remove large – particle impurities, residual chlorine, and some organic matters, reduce the turbidity of the raw water, and provide good inlet water conditions for the reverse osmosis membrane.
- High – pressure Pumping: The pretreated water is pressurized to 1.0 – 1.5MPa by a high – pressure pump to overcome the osmotic pressure of the reverse osmosis membrane and drive water molecules to pass through the reverse osmosis membrane.
- Membrane Separation: Water molecules selectively pass through the reverse osmosis membrane and enter the product water side, while impurities such as salts, organic matters, and bacteria are retained, forming highly concentrated concentrated water.
- Concentrated Water Discharge and Product Water Collection: The concentrated water is continuously discharged in a certain proportion to prevent salt concentration and scaling on the membrane surface; the product water is collected in the pure water tank or enters the subsequent deep – treatment process.
- Rinsing and Maintenance: The equipment is equipped with an automatic rinsing program. When the equipment stops, the reverse osmosis membrane is rinsed at low pressure to remove residual pollutants on the membrane surface and extend the service life of the membrane elements.

FAQ
Question 1: During the operation of the reverse osmosis equipment, how to determine whether the membrane elements need to be replaced?
Answer: When the following situations occur, the replacement of membrane elements should be considered: First, the water production decreases by 30% and cannot be restored by flushing; second, the desalination rate drops to below 95%; third, the operating pressure increases by 50% compared with the initial pressure. These phenomena indicate that the performance of the membrane elements has decreased significantly and cannot meet the water production requirements.
Question 2: Is the pretreatment process of the reverse osmosis equipment important? Can it be simplified?
Answer: The pretreatment process is of great importance and cannot be simplified. Good pretreatment can effectively remove suspended solids, colloids, organic matters, and residual chlorine in the raw water, preventing these substances from polluting and oxidizing the reverse osmosis membrane, extending the service life of the membrane elements, and reducing equipment maintenance costs. If the pretreatment is simplified, the reverse osmosis membrane will be blocked frequently, and its performance will decline rapidly, increasing operating costs and downtime risks instead.
