Chemical treatment systems are not only limited to wastewater management; they also play a significant role in air pollution control. Industries often emit volatile organic compounds (VOCs), particulate matter, and other pollutants into the atmosphere. One common method for treating emissions is the use of scrubbers that incorporate chemical reagents to capture these pollutants. For example, alkaline scrubbers can neutralize acidic gases like sulfur dioxide (SO₂) or hydrochloric acid (HCl) before they are released, mitigating their impact on air quality.
