Self-Regeneration of a Fixed Bed of Biologically Activated Carbon During Removal of 2-Chlorophenol from Water

Abstract

A contribution of self-bioregeneration of a sorbent in the course of removing from water of 2-chlorophenol by a stationary bed of biologically activated carbon (BAC) is assessed. The process of regenerating activated carbon is of a sporadic nature; the value, rate and efficiency of spontaneous bioregeneration were established. The total contribution of self-regeneration to the removal of 2-chlorophenol by the BAC bed during the experiment constituted 3.8–6.8%. In a stationary phase of biofiltration the losses of the volume of adsorption pores of activated carbon from vial activities of microorganisms exceed the total effect of the process of spontaneous regenerations.
