Packed Tower Scrubbers are one of the primary types of equipment, which is used to control odours at wastewater treatment facilities. It works on the principle such as the gas or airstream travels upwards through the tower meeting the scrubber liquid, which flows downwards on its way. It utilizes a vertical counter-current design for efficient absorption of a variety of toxic gases. It is used as a gas/liquid contactor in a number of process applications. It is ideal for tackling emergency situations. It handles strong flow fluctuations.
