What is the Preparation Process of Pure Water?

May. 15, 2020

As a China Pharmaceutical Equipment Manufacturer, share with you. Purified water can be prepared by electrodialysis, ion exchanger, reverse osmosis, distillation and other suitable processing methods. It is sealed in a container and does not contain any additives. It is colorless and transparent and can be directly consumed. .

The process of drinking pure water is:

Raw water

Sand filter

Carbon filter

Fine filtration

First-level reverse osmosis

Second-level reverse osmosis

Ozone sterilization

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

Pure Steam Generator

Pure Steam Generator

The most energy efficient membrane separation technology. Originally used for desalination of seawater, the pore size is very small, only 10-10, it can separate organic matter in the ion range and molecular weight of hundreds in the solution, remove dissolved salts, colloids, microorganisms, organic matter, etc. in the water, so as to obtain pure , Safe water.

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

Under normal circumstances, in the production process of purified water,

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, and the remaining 0.6 kg of water cannot be used as drinking water. For other purposes.

The pure water purifier has a good purification effect on anionic synthetic detergent, chloroform, nitrate, ammonia nitrogen, nitrite nitrogen and bacterial indicators, especially reverse osmosis (RO), which has a high salt removal rate and can remove harmful or potential harm to human health Hazardous substances. But in the process of pure water, essential 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 components.
