Estimation of Features of Activated Carbon Materials Used for DrinkingWater Purification

The adsorption parameters of the activated carbon (AC) BAU and KAU-TF, which have been used for purification of tap water over a long period of time, are estimated. It is shown, that the AC with the native biofilm is subjected to spontaneous bioregeneration. As a result of this process 68–96% of surface of AC mesopores is restored. To free the porous volume of the AC completely it is necessary to wash out the AC with the solutions of alkali and acid consistently after approximately two years of AC filter work.
