Abstract
This paper has investigated bioregeneration of biologically activated carbon (BAC) from procaine. The study has shown low efficiency (up to 25%) of desorption of procaine by aqueous solutions even at heating up to 80°C. In the course of bioregeneration media of spent BAC was recovered a small degree of adsorption capacity of the sorbent and by two times enhanced the ATP-ase activity of the biofilm, which increased the efficiency of the operation of biosorbents 2.5 and 3.25 times after respective 4 and 10 days of bioregeneration. A positive effect of bioregeneration affects further biofiltration about 1000 c.v. of the model solution.
