Wet Scrubbers are effective air pollution control devices for removing particles and/or Sox OR NOx gases from industrial exhaust streams. A Wet Scrubber operates by introducing the dirty gas stream with a scrubbing liquid – typically water and/or alkaline or lime preparation.Particulate or gases are collected in the scrubbing liquid. Wet Scrubbers are generally the most appropriate air pollution control device for collecting both particulate and gas in a single system. Range as per GPCB norms are

SPM – 150 mg/Nm³
SOx – 100 PPM
NOx – 50 PPM
