Reverse osmisis desalination equipment Introduction

Reverse osmosis equipment is a basic water treatment equipment that can further improve water quality to meet drinking requirements. In reverse osmosis equipment, there are two forms, both single-stage and double-stage, and both of them also have There is a big difference.

Equipment characteristics

The use of reverse osmosis system, especially the pre-treatment of raw water. In order to avoid clogging of the reverse osmosis system, the water should be pretreated to eliminate suspended matter in the water and reduce the turbidity of the water; in addition, it should be disinfected to prevent the growth of microorganisms. Due to the high requirements for suspended sediment in raw water, the water quality for water quality testing is usually used. This method is basically a case for the determination of water suspended solids in reverse osmosis systems. The pollution index of water entering reverse osmosis equipment does not exceed 5, and the recommended value is generally less than 3.

Reverse osmosis equipment is to pass raw water through fine filters, granular activated carbon filters, compressed activated carbon filters, etc., and then pressurized by pumps, reverse osmosis membranes, make higher concentration water into low concentration water, and at the same time pollute industrial pollution A large amount of impurities such as substances, heavy metals, bacteria, viruses, etc. mixed into the water are isolated, so as to meet the physical and chemical indicators and hygienic standards prescribed by drinking, and output to clean to pure water.

Main factors affecting the desalination rate and normal operation of reverse osmosis equipment

1. Ion valence: the desalination rate increases with the increase of the ionic valence, the desalination rate of bivalent and trivalent salts is higher than that of monovalent salts;

2. Molecular size: the desalination rate increases with the increase of molecular diameter;

3. Raw water temperature: When the raw water temperature increases, the desalination rate increases due to the decrease of the viscosity of the water;

4. Raw water concentration: When the raw water concentration increases, the desalination rate decreases;

5. Working pressure: when the working pressure increases, the desalination rate increases but is not obvious;

6. PH value: Although the membrane is not easy to block under acidic conditions, the desalination rate should be reduced;

7. Dissolved gas: soluble gas can easily penetrate in free state without removing CO2, SO2, O2, Cl2, H2S, etc .;

8. Hydrogen bond trend: For compounds containing strong hydrogen bonds, the removal rate is very low, such as water, phenol, and ammonia;

9. Organic matter: organic matter in water has a polluting effect on the membrane, the more organic matter the membrane performance is likely to deteriorate;

10. Water hardness: the higher the hardness of the water, the easier the membrane becomes clogged. For high hardness water, it should be softened first, and the hardness should be reduced before entering reverse osmosis

11. Solid particles: solid particles are extremely harmful to the reverse osmosis membrane and must be pretreated;

12. Microorganisms: microorganisms and bacteria in water are harmful to the membrane and must be pretreated (the company uses ultrafiltration membranes for treatment, which is at an advanced level in China);

13. Oxides: Metal oxides cannot enter the reverse osmosis to remove themselves, and should be removed regularly by chemical drugs.
