Standard RO System Process
Raw water pump - Sand filter - Carbon filter - Dosing system - Cartridge filter - High pressure pump-RO membrane host
The Role of RO Process Each Component
| 1 | Raw water tank | The original water tank has a simpler function and is used for storing raw water. This is afraid that the original water will not be available for a transit. |
| 2 | Raw water pump | The raw water pump provides the raw water pressure for the raw water pretreatment system. If the raw water is under pressure, you can completely avoid this equipment. General requirements for raw water pressure >= 0.3MP |
| 3 | Quartz sand filter | This equipment is mainly used to filter microorganisms and dust in the water to make the raw water clear. |
| 4 | Activated carbon filter | The equipment is mainly used to filter residual chlorine in water. |
| 5 | Dosing system (cation exchange system) | Small systems use cation exchange systems; large systems use dosing systems to add scale inhibitors directly into the system. |
| 6 | Precision filter | It mainly filters large particles in water. |
| 7 | Special high pressure pump | Provides strong power for reverse osmosis equipment. |
| 8 | Reverse osmosis membrane | The reverse osmosis membrane uses membrane filtration technology. Let water molecules pass through other ions to achieve the purpose of purifying water. |
Application Range of Reverse Osmosis Pure Water Equipment
1. Preparation of pure water and ultrapure water in industries such as electronics, industry, medicine, food, etc.;
2. Purification and preparation water for process water/chemical circulating water and chemical product manufacturing in light textile and chemical industry;
3. Water for purification and preparation of water for food and beverage industry, drinking pure water, beverages, beer, liquor, health care products, etc.;
4. In the industrial production, the useful substance and concentration and recovery of the aqueous solution;
5. Pre-desalting treatment of high-pressure boiler feed water in boilers such as boiler feed water, thermal power boilers, mines and low-pressure boiler power systems in power industry;
6. Desalination of brackish water and seawater;
7. The pure water device is used as a first-grade desalination equipment for high-purity water production.
8. Communities, real estate properties, schools, factories, hospitals, tea houses, hotels, beauty salons, canteens, etc.
9. It can be used for the preparation of bottled water, mineral water and other filling water.
10. Water for electronic industry Washing water for electronic components such as integrated circuits, silicon wafers, display tubes, etc.
11. Water for the pharmaceutical industry, large infusions, injections, tablets, biochemical products, equipment cleaning, etc.;
12. Seawater, brackish water desalination Island, ship, offshore drilling platform, brackish water area
13. Other process water Ultra-pure water for automobile, home appliance coating, coated glass, cosmetics, fine chemicals, etc.
CIP System to Chemical Cleaning
Under normal operating conditions, reverse osmosis membranes may also be contaminated by inorganic scales, colloids, microorganisms, metal oxides, etc. These substances may deposit on the surface of the membrane, causing a decrease in the output of the reverse osmosis unit of the water purification equipment or a decrease in the salt rejection rate. It rises and even causes irreparable damage to the membrane. Therefore, in order to restore good water permeability and desalination performance, the membrane needs to be chemically cleaned.
