More than 200 constructions of bioscrubbing of sewage are operating now in Belarus, which refine the basic quantity of the Industrial and household sewage draining to the water objects. One of perspective ways of increasing of sewage treatment and sewage disposal plants of the water drain suitable to operating conditions is using for these purposes of bioflocculants. With reference to sewage disposal plants of the water drain the greatest interest represents using as flocculant of active silt of cell material. Results of researches testify that ultrasonic processing at the certain capacity of a radiator and amplitude of fluctuations allows to receive bioflocculant which is expedient for using on sewage disposal plants of the water drain for increasing in the purification efficiency from suspended matters and productivity of the equipment for the mechanical cleaning of sewage.
