Any item has a life cycle. Of course, Activated Carbon For Environmental Protection is no exception. What is the service life of activated carbon? How long should it be replaced?
The most important thing of activated carbon in the treatment of any substance is the adsorption capacity. With the adsorption of different substances and substances, the adsorption capacity of activated carbon will start to decrease with time. Therefore, in order to maintain good adsorption capacity when using activated carbon, it should be replaced regularly. . Any kind of activated carbon adsorption capacity is limited, but different types of activated carbon have different adsorption characteristics in different environments.
The adsorption capacity of activated carbon is directly related to the iodine value. The higher the iodine value of activated carbon, the stronger its adsorption capacity. In the process of filtering activated matter, the activated carbon particles and pore size must be larger than the adsorbate according to the molecular size of the adsorbed material. In order to completely adsorb the adsorbed material. When activated carbon is used in the water treatment industry, the higher the content of adsorbed substances in the water, the faster the adsorption capacity of activated carbon will be lost. The adsorption cycle of activated carbon and the temperature of water, the adsorption environment, and the content of adsorbed substances in water are all high. close relationship. When the activated carbon is saturated, it should be replaced immediately. In order to lose the adsorption capacity, the water quality will not reach the standard and bring unnecessary losses to the enterprise. The adsorption capacity of activated carbon is also directly related to the contact time of the adsorbed material. The longer the contact time, the better the adsorption effect. Multilayer Particles Activated Carbon has a greater advantage in the treatment of sewage than the use of powdered activated carbon, because powdered activated carbon is difficult to control in water, and its effect is greatly reduced. The granular activated carbon is not easy to flow in water, and the organic substances in the water are less likely to be clogged in the filter, and the replacement is convenient.
