How long does the activated carbon need to be replaced

According to the different raw materials, activated carbon includes coal activated carbon, wood activated carbon, fruit shell activated carbon, coconut shell activated carbon, etc. according to the different fields of use, the length of use of activated carbon is also different.

For example, the application of wooden activated carbon in water treatment mainly observes the change of water quality. When the treatment effect of pollutants in water is weakened, it indicates that the adsorption performance of activated carbon is reduced and tends to be saturated at this time, and new activated carbon needs to be replaced.

For example:

It is recommended to replace the activated carbon in the fish tank once or twice a month. In the early stage of using activated carbon, pay attention to observe the change of water quality, so as to change the quantitative activated carbon in the later stage more accurately and ensure the water quality in the fish tank. Generally, the more the amount of activated carbon is, the better the water quality is.

There are granular activated carbon and powdered activated carbon used in industrial wastewater treatment, and the corresponding process conditions are different. Granular activated carbon is used for continuous adsorption, and the treated water is purified through the wooden activated carbon adsorption bed; powdered activated carbon is used for intermittent adsorption, that is, according to a certain proportion, powdered carbon is added to the treated water, mixed evenly, and the carbon and water are separated by sedimentation or filtration.

If activated carbon is used to deal with industrial waste gas or formaldehyde and other pollutants in new houses, it is necessary to measure the content of harmful substances in the air to determine whether a new carbon needs to be replaced, so as to ensure that the waste gas can meet the emission standards or maintain the air quality of new houses.

The duration of wooden activated carbon has a lot to do with the adsorption capacity of activated carbon itself, the concentration of adsorbate, the amount of treatment, the conditions of use, etc. it is suggested that enterprises should consider the influencing factors in all aspects when selecting activated carbon. They can consult the technical personnel of wooden activated carbon manufacturers to find out how much to use, how to replace and the replacement time. They will give a more clear indication This can improve the use efficiency of wooden activated carbon and save the operation cost.
