Principle of bioactive carbon reactor

The principle of the Biological Active Carbon (BAC) is to domesticate microorganisms on the surface of activated carbon to form a fixed growth biofilm to decompose organic pollutants from waste water. Bioactive carbon has a strong adsorption capacity, and organic pollutants are adsorbed on the active substrate. The biofilm on the activated carbon particles adapts to the pollutant and decomposes it, and the vacated active group can restore the adsorption capacity, and then adsorb the organic matter. . In this way, the adsorption process of adsorption, desorption, regeneration and adsorption is maintained, and the adsorption capacity of the activated carbon surface is maintained, which is called “bioregeneration”.

If the amount of biological regeneration in the bioactive carbon system is greater than the amount of activated carbon adsorbed, it is not necessary to take out the activated carbon and regenerate it by other methods. In addition, the sludge retention time of the bioactive carbon treatment system is very long, so the amount of sludge generated is extremely small.
