Solutions include amine scrubbers for acid gas removal and wet limestone scrubbers for flue gas desulfurization. These systems ensure compliance with environmental regulations like the Clean Air Act.

Semiconductor Manufacturing

High-purity scrubbers are used to eliminate volatile organic compounds (VOCs) and toxic gases such as arsine and phosphine from cleanroom exhaust. Chemical scrubbers with activated carbon or catalytic oxidation are common, achieving removal efficiencies above 99%.

Pharmaceutical Production

Scrub systems control solvent vapors and hazardous air pollutants (HAPs) during drug synthesis. Solutions include packed bed scrubbers using water or caustic solutions, often integrated with solvent recovery units to reduce waste.

Wastewater Treatment

Odor control scrubbers neutralize hydrogen sulfide and ammonia from sewage treatment plants. Biological scrubbers and chemical scrubbers with sodium hypochlorite are widely adopted, offering low operating costs and high reliability.

Power Generation

Coal-fired power plants use wet flue gas desulfurization (FGD) scrubbers to reduce SO₂ emissions. Advanced solutions include seawater scrubbers for coastal plants and dry scrubbers for water-scarce regions.
