The difference between the post-composite cartridge of the water purifier and other cartridges

The difference between the post-composite cartridge of the water purifier and other cartridges is as follows:

1, there is a difference in function:

The pre-activated carbon cartridge of the water purifier is used to adsorb odors and residual chlorine, and the post-activated carbon cartridge serves to improve the taste and sometimes remove the smell of the traditional storage bucket.

2, the replacement cycle is different:

The replacement cycle of the pre-filter is usually about 6-12 months, because of the need to filter the impurities in the water, so the replacement cycle can not be too long. After the activated carbon intercepted pollutants than the former activated carbon intercepted pollutants much less, so the replacement cycle is longer than the former activated carbon. It is recommended that the replacement cycle for the rear activated carbon be 2-3 times the 12-month replacement cycle.

After using the water purifier for a period of time, it is recommended to replace the activated carbon immediately if you feel that the taste is a little odor. If there is no odor, it is recommended that the replacement cycle does not exceed 48 months.

Extended information:

p>The main component of the post-composite cartridge of the core water purifier and other cartridges is activated carbon.

1, after the activated carbon installation location:

After the activated carbon as a water purifier filtration components, generally located in the host of ultrafiltration membranes, reverse osmosis membranes and other cartridge components of the rear, and therefore also known as the rear activated carbon cartridge.

The raw water passes through the host cartridge to reach the water storage tank. After the water comes out of the storage tank, it passes through the post-activated carbon cartridge and reaches the faucet where we usually receive water.

2, after the main function of the activated carbon:

As we all know, each part placed in the water purifier has its own special purpose, such as the filter valve port is used to filter large particles of impurities, ultrafiltration and reverse osmosis membranes can be removed to remove invisible to the naked eye of the bacteria, viruses, heavy metal ions, and so on, while the activated carbon is generally through the absorption to play a role.

In practice, due to the high precision of the reverse osmosis membrane, filtration resistance, slow water production, can only be slowly purified water stored in the pressure storage tank. The pressure tank is equipped with a rubber airbag, and the water pressure is discharged through the pressure between the water storage airbag and the tank. In this case, the purified water will have a little rubber flavor after a long time in contact with the rubber, which has a certain effect on the taste.
