Gas–liquid contact systems that wash particulates and soluble gases out of exhaust streams.
Exhaust gas is forced through a scrubbing liquid — water or an alkaline solution — inside a packed tower or venturi. Particulates and soluble gases transfer into the liquid.
Packing, spray nozzles and mist eliminators are selected per pollutant. The scrubbing liquid is recirculated with fresh make-up, and the bleed-off is routed to the ETP.
Hot, dirty gas enters the scrubber tower.

Droplets removed from the clean gas.
Liquid recycled; bleed-off to ETP.
Scrubbing liquid recirculates with fresh make-up; bleed-off goes to the ETP.
Final specifications are engineered per site after requirement study.
