The article presents the findings of the experimental studies of mechanical regeneration of the immobilized load using an electromechanical unbalanced vibrator. The sedimentation of the sludge on the synthetic load inside the physical model of a vertical bioreactor is studied. Mechanical regeneration of the immobilized sludge on the brush is proposed. The nature of dependence between the concentration of free-floating sludge and the deposition time following the mechanical regeneration is identified. The kinetics of the sludge deposition, the dose and intensity of aeration is studied, if the electric vibrator is used for the mechanical regeneration of the brush load. Thus, the application of the plane model of a bioreactor helped to determine that, if the water-sludge mixture has a small concentration of the free-floating sludge, the sedimentation is about 10 % of the total dose 30 seconds after the mechanical regeneration of the brush load. The effectiveness of the mechanical regeneration performed with the help of an electromechanical unbalanced vibrator was approximately 84–90 %. The application of the bioreactor having a synthetic brush load mechanism increases the concentration of the coagulated activated sludge.
