Reverse osmosis RO water treatment mainly includes: multi-media filter, activated carbon filter, water softener, PP precision filter, reverse osmosis system, ultrafiltration system, ultraviolet sterilization system, ozone sterilization system, and electrical control system. Preprocessing includes multi-media filters, activated carbon filters, softeners, iron and manganese removal filters, ultrafiltration, microfiltration, etc; Deep processing includes membrane treatment and ion exchange; Terminal processing includes ozone, UV and other methods, as well as polishing mixed bed, EDI or CDI processing.
Main components of reverse osmosis RO water treatment:
1. Water tank:
The water tank set by the system ensures a buffering and adjustment capacity of 30-60 minutes. Alternatively, larger or smaller water tanks can be set up as buffer water tanks between equipment according to customer requirements. The water tank is equipped with a liquid level switch, a respirator, a liquid level pipe, and a pneumatic inlet valve for easy automatic control of the entire line.
2. Multi media filter:
The main purpose of using multi-stage graded quartz sand filter media and anthracite as filtration media for water treatment is to remove larger suspended particles and dissolved organic macromolecular pollutants in water, and reduce water turbidity.
3. Activated carbon filter:
The use of water treatment specific palm shells as activated carbon filter media is mainly aimed at adsorbing organic matter, residual chlorine, and odors in water, and serving as a guarantee facility for improving water quality in the beverage industry.
4. Precision filter:
A precision filter of 5 μ m or 1um is installed at the inlet of the reverse osmosis host to ensure the removal of residual activated carbon and substances such as scale and rust in the water, and to intercept any small particles that may be present in the inlet water to protect the reverse osmosis membrane from damage.
5. Membrane separation system or ultrafiltration
The principle of membrane separation system is a principle of membrane separation process. Ultrafiltration uses a pressure active membrane to intercept colloids, particles, and substances with relatively high molecular weight in water under external driving force (pressure), while water and small solute particles pass through the membrane in the separation process.
6. Reverse osmosis system:
Reverse osmosis is a high-tech membrane separation technology that uses pressure difference as a driving force for cross flow membrane filtration (including ultrafiltration, nanofiltration, and reverse osmosis). It has the characteristics of high separation efficiency, no phase change, and simplicity. The reverse osmosis system is also equipped with a 5 μ m security filter, a high-pressure pump, high and low pressure protection and control. Most organic compounds can be removed with a removal rate of 99%, and the removal rates of viruses, bacteria, and pyrogen are greater than 99%.
7. Ozone sterilization system:
Ozone is a particularly strong oxidant, with an instantaneous sterilization property 16 times that of chlorine, and meets the national requirements for drinking water - no residual harmful products.
8、EDI：
Continuous Electrodeionization (EDI) is the process of using mixed bed ion exchange resin to adsorb cations and anions in water, and these adsorbed ions are continuously removed through cation exchange membranes under the action of direct current voltage.
9. UV sterilizer:
Ultraviolet sterilization exists in the form of electromagnetic or radiation energy. It uses ultraviolet radiation with a wavelength of 2000-3900A (1A=1X10-10m) to effectively destroy the DNA molecules of microorganisms, forming TT dimers that cannot reproduce. It is a commonly used and safe sterilization method for air and water.
10. Mixed bed:
The mixed bed ion exchanger is composed of anion exchange resin and cation exchange resin mixed in proportion.
