The working mechanism of a vertical scrubber involves the upward movement of contaminated air through the packing material in the tower. Simultaneously, the scrubbing medium is introduced from the top and flows downwards in a countercurrent fashion against the air. This process facilitates the removal of pollutants from the air. The cleaned air then exits from the top of the tower, where it can be safely released into the atmosphere or sent for further processing. The pollutants are collected at the bottom in the waste, which requires additional treatment or disposal. The system includes automated controls to regulate air flow rates, scrubbing medium, pH levels, and pressure differentials, ensuring optimal efficiency.
