As a China Pharmaceutical Equipment Manufacturer, share with you.

Pure water can be prepared by electrodialysis method, ion exchanger method, reverse osmosis method, distillation method and other appropriate processing methods. It is sealed in a container and does not contain any additives. It is colorless and transparent and can be consumed directly.

The process of drinking purified water is:

Raw water

Sand filter

Carbon filter

Fine filtration

First-level reverse osmosis

Secondary reverse osmosis

Ozone sterilization

The process of pure water is strict, especially the reverse osmosis technology is the most advanced.

The most energy-saving and effective membrane separation technology. Initially used for seawater desalination, its pore size is very small, only 10-10. It can separate organics in the ionic range and molecular weight of several hundred in the solution, remove dissolved salts, colloids, microorganisms, organics, etc. in the water to obtain pure, safe water.

The reverse osmosis technology is to pass the raw water through a fine filter, granular activated carbon filter, activated carbon filter, etc., and then pressurize it by a pump, using a pore size of 1/10000μm (equivalent to 1/6000 the size of E. coli, 1/6000 the size of the virus). 300) reverse osmosis membrane (RO membrane), which turns high-concentration water into low-concentration water, and at the same time isolates all the impurities mixed into the water such as industrial pollutants, heavy metals, bacteria, and viruses, so as to achieve the physical and chemical indicators specified for drinking And hygiene standards. Reverse osmosis equipment uses membrane separation technology to effectively remove charged ions, inorganic substances, colloidal particles, bacteria and organic substances in the water.

In general, pure water is in the production process, only 50%-75% of the source water is used, that is to say, 1 kg of tap water or groundwater can only produce about 0.4 kg of pure water, while the remaining 0.6 kg of water cannot be used as drinking water. For other purposes.

In China, the hygienic requirements for the effluent quality of water purifiers should meet the requirements of the "Regulations on Hygienic Safety and Functional Evaluation of Reverse Osmosis Drinking Water Treatment Devices" promulgated by the Ministry of Health of the People's Republic of China in 1998.

The water purifier has a better purification effect on anionic synthetic detergent, chloroform, nitrate, ammonia nitrogen, nitrite nitrogen and bacterial indicators, especially the reverse osmosis (RO) type. The salt removal rate is high, and it can remove harmful or potentially harmful to human health. Of hazardous substances. However, in the process of pure water, the necessary trace elements such as Cu, Fe, Zn, F or macro elements S, P, Ca, Mg, Na, K are also removed, and the higher the pure water rate, the various benefits The greater the loss of human health ingredients.
