Operating Principle :

• Contaminated air moves horizontally through a packed bed .

• It is irrigated /wetted by scrubbing liquid flowing down through the packing

• Mass transfer achieved by a combination of diffusion , physical absorption and /or chemical reaction

• Gas collection efficiencies a function of 

• Irrigation rates.

• Packing depth . 

• Composition of Recirculating scrubbing liquids.

Benefits :

• Low recirculation scrubbing liquid rates. 

• High volume air flow .

• Low pressure drops .

• Ideally suited for congested place Installations or where headroom is limited 

• Supplied inbuilt with recirculation tank .

• System Centrifugal fan can be connected directly to the scrubber outlet saving space and cost.

• Combined flexibility of efficient removal of gas , liquid or solid contaminants from air streams .
