1. Different roles
The pre-activated carbon of the water purifier absorbs odor and residual chlorine. The rear activated carbon filter is to improve the taste, or sometimes remove the smell from the traditional storage tank.https://www.activated-carbon-pellets.com/
We all know that every component placed in the water purifier has its own very special purpose, such as: PP cotton is used to filter large particles of impurities, ultrafiltration membrane and RO membrane can remove invisible bacteria and viruses , Heavy metal ions, etc., activated carbon generally plays a role mainly through adsorption.
In actual use, due to the high precision of the RO membrane, high filtration resistance, and slow water production speed, only slowly purified water can be stored in a pressure water storage tank. A rubber balloon is placed in the pressure tank, and the water is forced out by the pressure between the water storage balloon and the tank body. In this case, the purified water will have a little rubbery smell after being in contact with rubber for a long time, which will have a certain impact on the taste. Therefore, post-activated carbon or other technologies are needed to improve the taste.
2. Different activated carbon raw materials
Pre-activated carbon is mainly used to absorb different colors, odors, odors, residual chlorine, etc., coal-based granular activated carbon is often used as the pre-activated carbon of household water purifiers. Because the carbon structure has more surface functional groups, it is more effective in chemical adsorption. The coconut shell activated carbon with relatively stable structure has more advantages.https://www.coconutactivatedcarbon.com/
The post activated carbon is mainly to improve the taste and control the growth of bacteria. The activated carbon itself needs to be of high purity, so pickling coconut shell activated carbon should be selected, and some consider the use of silver-loaded coconut shell activated carbon for bacteriostasis.
3. Different locations
The pre-activated carbon is generally located in the secondary filtration position. The raw water is firstly filtered through PP cotton to intercept large particles of impurities, and then passed through the pre-activated carbon to absorb different colors and odors, and then flow through other filter elements for deep filtration.
The post activated carbon is generally located behind the main unit filter element, so it is called the post activated carbon filter. The raw water reaches the water storage tank after passing through the filter element assembly of the host. After the water comes out of the water storage tank, it passes through the post activated carbon filter element to the faucet.
4. The replacement cycle is different
The replacement cycle of pre-activated carbon is generally about 6-12 months, because it needs to filter impurities in the water, so the replacement cycle cannot be too long. The rear activated carbon has to intercept much less pollutants than the front, so the replacement cycle is longer than that of the front activated carbon. It is recommended that the replacement cycle of post activated carbon is about 24 months.
