Summary of the whole house water purification project
Whole house water purification project Hongrui Hi-Tech: At present, the purification technology of domestic water purifiers basically uses filtration membrane separation technology, which is mainly divided according to the filtration accuracy, and its filtration accuracy can be divided into reverse osmosis from high to low. Water purification technology, nanofiltration water purification technology, ultrafiltration water purification technology, microfiltration water purification technology.
Whole house water purification project household five-stage water purifier 1. Reverse osmosis (RO) membrane: Reverse osmosis membrane is a kind of water purification technology membrane with the highest filtration accuracy on the market. Its principle is to use pressure difference to achieve water separation , Can almost completely remove all substances in the water including good and harmful to the human body. In the process of purifying water, nearly 50% of wastewater is generated, so it is generally used in the manufacture of domestic direct drinking water, industrial ultrapure water, and medical ultrapure water. Need to be powered and pressurized during use.
2. Nanofiltration (NF) membrane for whole house water purification project : its filtration accuracy is between 0.01 and 0.0001, that is, between ultrafiltration membrane and reverse osmosis membrane, and it needs to be powered like the reverse osmosis membrane. And pressurization, but the desalination rate is lower than the reverse osmosis membrane, and the amount of wastewater is large, it will be close to 30% of tap water, so it is generally different from domestic water, but used for industrial pure water manufacturing.
3. Ultrafiltration (UF) membrane: It is also a membrane separation technology that uses pressure difference to separate. Its filtration accuracy is 0.01 microns, which can effectively remove harmful substances such as bacteria, viruses, macromolecular organics, colloids, and residual chlorine in the water, and retain some mineral elements in the water. Ultrafiltration water purifier produces little waste water, and it does not need to be powered and pressurized during use. It can be filtered by the impact pressure of tap water, and the water production is also large. Used with other filter elements to provide direct drinking water for the home.
4. Whole house water purification engineering microfiltration (MF): Microfiltration refers to all filter materials with a filtration accuracy of 0.1-50 microns, including activated carbon, PP cotton, ceramic filter elements, etc. Its function is because its filtration accuracy is low, it can only perform a simple filtration on water, it can only filter some sediment, rust, residual chlorine, etc., and it can not achieve purification effect on some harmful bacteria, viruses and other harmful substances in water. And its filter element can not be cleaned generally, it is a disposable filter material, the filter element should be replaced frequently after it expires.
