What Will Affect The Service Life of Coconut Shell Activated Carbon Water Filter Cartridge?

Generally speaking, the service life of coconut shell activated carbon filter cartridge used in water treatment is 2-3 years, but this is a general calendar value. Its specific operating time is easily affected by many factors such as the quality of raw materials of coconut shell activated carbon water filter. The specific surface area of good-quality coconut shell activated carbon should be 1000m2 / g, and the mechanical strength should be above 90%.  With strong adsorption capacity and fast filtration speed,It is not easy to move due to particle formation, and impurities such as organic matter in water are not easy to block in the coconut shell activated carbon filter layer.

What will affect the service life of coconut shell activated carbon water filter cartridge?

  1. Water output.

 Assuming that the daily water output is large, the service life of the coconut shell activated carbon water filter cartridge will be relatively shortened, and each kilogram of coconut shell activated carbon can control 20 tons of water filtration capacity.

2. Water temperature.

The higher the water temperature, the stronger the adsorption capacity of the coconut shell activated carbon cartridge; but when the water temperature is higher than 30 ° C, the adsorption capacity of the coconut shell activated carbon filter will reach its limit, and its adsorption performance will gradually decrease.

3. PH value of water quality.

When the water quality is acidic, the adsorption capacity of the coconut shell activated carbon water filter cartridge for anionic substances is relatively weakened; when the water quality is alkaline, the adsorption capacity of the coconut shell activated carbon water filter for cationic substances is weakened. Therefore, the pH value of the water quality is unstable, which will also affect the adsorption capacity of the coconut shell activated carbon water filter. The adsorption capacity of coconut shell activated carbon cartridge is directly proportional to the contact time with water. The longer the contact time, the better the filtered water quality.

In general, we can use hydrochloric acid to modify the coconut shell activated carbon filter in practice to improve its adsorption performance. Similarly, in the process of using coconut shell activated carbon filter, we can use the chemical properties of the surface of the adsorbent and the adsorbent to find more effective adsorption methods through product experiments to improve our use efficiency and purification efficiency.

The above is our summary of the factors affecting the life of coconut shell activated carbon filter cartridges by Huatan Filter. We hope to help you understand the activated carbon block products.

The Service Life of Residential Water Filter Cartridge You Must Know

With the improvement of people’s living standards and health and environmental protection, residential water filters have become very high-use household appliances. However, the filter cartridge of the water purifier needs to be replaced regularly so as to fully ensure a good purification effect.

1. How long is the service life of the water filter cartridge?

At present, most water purifier manufacturers will set a service life for the water filter cartridge. For example, the service life of the ultrafiltration membrane filter cartridge is generally 24-36 months; the service life of the reverse osmosis (RO) membrane cartridge is generally In about 18 months, the service life of the adsorbent filter cartridge such as activated carbon filter cartridge is generally about half a year to about one year. The filter cartridge that does not discharge sewage, such as pp cotton, can only be used for about 3 months. Most of these service life is determined by the water filter manufacturer based on the actual water output of the water purifier. This method is also the result of testing in the urban tap water environment; of course, these theories do not represent the service life of the water filter cartridge in the actual daily life. The actual service life of the filter cartridge has a great relationship with the maintenance.

2.When does the water filter cartridge need to be replaced?

A.Ultra-filter and RO membrane : When the water output of the water purifier is greatly reduced, it is much smaller than the original water flow or does not return to the original water output after washing, which can not meet your water demand. At this time, you need to replace the filter cartridge.

B.compound activated carbon filter: When you feel that the taste of purified water is poor and unacceptable, you need to replace the carbon block filter cartridge. In addition, regardless of the frequency of use, if the filter cartridge is installed or replaced for more than one year, it must be replaced.

C.PP cotton filter: the cartridge is usually replaced once every three months. You can judge whether to replace it by observing the color change of PP cotton filter. The use time of PP cotton filter cartridge can not exceed six months.

In fact, the water filter determines the health of the drinking water in the home. If the filter cartridge is not replaced for a long time, it may cause “secondary pollution” to the filtered water. Therefore, the water purifier must maintain and replace the filter cartridge in daily use. We only pay attention to the maintenance of water purifiers,and replace the filter cartridge in time according to the water quality, product condition and water consumption to ensure that the water quality of the purified water meets the qualified drinking standard, and  achieve the best performance of the water filter.

Of course, if the water output of the filter is small, it generally does not mean that the quality of the filter cartridge is not good. The main reason may be low water pressure or poor raw water quality, which causes the filter element to clog.
