Water pollution is getting worse. It is reported that among the seven major water systems in my country, nearly 40% of the water sources are not suitable for drinking water. 78% of the river sections in urban waters are not suitable for drinking water sources, and about 50% of urban groundwater is polluted. These astonishing numbers on May 1 do not reveal a problem. The water pollution in our country is getting worse.


However, everyone needs to drink and use water, and water is the most indispensable thing in our daily lives. Water pollution is becoming more and more serious, and the secondary pollution of tap water cannot be ignored.

The relevant personnel of the drinking fountain pointed out that at present, our country generally adopts the method of water treatment in water plants, and then the method of transporting to the households through the tap water pipeline to supply drinking water. However, the simple treatment processes used in the treatment of tap water in my country, such as pre-sedimentation, coagulation, clarification, sand and gravel filtration, and bleaching powder disinfection, cannot remove chemical pollution and heavy metal pollution in the water. Sub-pollution, these artificially treated water not only fail to ensure the safety of drinking water, but become new pollution that affects health.

This source of life, youth, health, and beauty is suffering unprecedented destruction and pollution. In the 21st century, how many people can still drink healthy and safe water easily? Water pollution is getting worse and this has given birth to a new industry. ----Water Purifier.

With the birth of the world's first direct drinking machine—water purifier, people finally ushered in a new era of healthy drinking water. Direct drinking water machine—The water purifier uses a combination of new technologies and new processes such as activated carbon adsorption, reverse osmosis membrane treatment and sterilization technology to produce high-standard water requirements suitable for drinking water, kitchen water and bathing water, so as to make water evenly. The advantages of low cost, high quality of effluent, simple and convenient operation, and strong adaptability have become the mainstream way to meet residential water demand in the post-industrial era.
