Internal structure of RO reverse osmosis water purifier

Reverse osmosis water purifiers generally require five levels of filtration:
The first stage is a PP cotton filter element, the second stage is a pre-granular carbon filter element, the third stage is a compressed activated carbon filter element, the fourth stage is the core RO reverse osmosis membrane filter element, and the fifth stage is a post-activated carbon (small T33). Generally speaking, five-level filtering settings are more reasonable.
● PP cotton filter element
5 micron pore size filter element removes residual sediment, rust and other tiny impurities in the water
● Pre-granular carbon filter element
It is made from carbonaceous materials such as essence, coal, and fruit shell (core) through chemical or physical activation methods. It has a lot of micropores and specific surface area, so it has strong adsorption capacity and can effectively absorb organic pollutants in water. In addition, during the activation process, the amorphous parts of the activated carbon surface form some oxygen-containing functional groups. These groups give the activated carbon chemical adsorption and catalytic oxidation and reduction properties, and can effectively remove some metal ions in the water.
● Compressed activated carbon filter element
Further remove residual chlorine, odor, and solid impurities from water.
● RO reverse osmosis membrane filter element
The most effective removal of calcium, magnesium, bacteria, organic matter, inorganic matter, metal ions and radioactive substances in water. The crystal clear and sweet glycol purified by this device. The water quality filtered by the RO membrane does not contain substances harmful to the body, and the minerals beneficial to the body are preserved. Long-term drinking of water purified by the RO filter element will not have side effects on the body.
● Post activated carbon
It can better improve the taste of water.
