The scrubber is based on the principle of absorption of the supplied medium by the liquid and its purification from suspended particles in the technological process. At the same time, there is an intensive mass exchange between the phases. Compounds from the gas fraction pass into the liquid fraction. The purified gas fraction is discharged into the atmosphere, and the liquid fraction, together with the sludge, enters the storage tank of the scrubber through the drain pipe. Periodically, the liquid phase from the scrubber tank is sent for post-treatment and further into the sewer. The resulting solution from the scrubber tank can be reused.
