Basic configuration requirements of pure water filter element

The filter element can remove a small amount of solid particles in the liquid or the air, which can protect the normal operation of the equipment or the cleanliness of the air. When the fluid enters the filter element with a certain size filter screen, its impurities are blocked, and the clean fluid flows out through the filter element. Hydraulic oil filter element Wolfman liquid filter element makes the liquid (including oil, water, etc.) clean the contaminated liquid to the state required for production and life, that is, to make the liquid reach a certain degree of cleanliness. The first stage: 5μm PPF filter element - the pore size of the PPF filter element is 5 microns, which can effectively filter out coarse solid impurities such as rust, sand and gravel in the water. The second stage: granular activated carbon filter element - granular activated carbon with high adsorption, which can effectively absorb chlorine, odor, different colors and other substances in water. The third stage: 1μmPPF filter element - 1μmPPF filter element can more effectively remove small molecular particles in water. The fourth stage: RO membrane - a reverse osmosis membrane with a pore size of 0.0001 microns, which can effectively remove harmful substances such as bacteria, toxins, heavy metal ions, and salts in the water. The fifth level: post activated carbon filter element - to improve the taste of pure water. As we all know, the first three-stage filtration is for the RO membrane. As the pretreatment of raw water, it is designed to increase the service life of the RO membrane. Then the first filter element of the RO membrane of the pure water machine is still 1μmPP cotton is better. There are three reasons: 1. It can effectively prevent the activated carbon powder from entering the RO membrane, and protect the RO membrane to minimize the entry of activated carbon powder and prolong its service life. Because before installing the activated carbon filter element, no matter how clean it is, there will be carbon powder flowing out. Installing a 1μm filter element before the RO membrane can act as a barrier, greatly reducing the possibility of artificial pollution of the RO membrane. 2. The filtration accuracy of 1μm PP cotton is 1 μm, and harmful substances such as bacteria, sediment particles, and rust larger than 1 μm can be removed as much as possible. When the first 5μm filter element fails, it can still protect the RO membrane and reduce the RO membrane. probability of contamination. 3. If the third stage is block compressed activated carbon or sintered activated carbon CTO, three of the five stages of filtration are activated carbon, and the activated carbon filter element is reused, which not only wastes resources, but also increases costs. Losing its due effect is not worth the gain. The second stage is generally granular activated carbon, which needs to be washed during installation, which often causes a lot of black water, and it is easy to be washed out. If it is changed to compressed activated carbon black water, the problem will be solved, and the burden of the third-level PP cotton will not be increased.
