Air Pollution Control — Packed Bed

Venturi wet scrubbers, packed bed scrubbers (99.9% gas absorption), cyclonic spray scrubbers & welding fume collectors.

A wet scrubber is an air pollution control device that removes harmful gaseous pollutants (SO₂, HCl, HF, NH₃, H₂S, VOCs) and fine particulate matter from industrial exhaust by bringing contaminated gas into intimate contact with a scrubbing liquid — typically water, caustic soda solution, or chemical reagent. The pollutant molecules are either physically absorbed into the liquid, chemically neutralized (acid-base reaction), or physically trapped by water droplets and mist. Wet scrubbers are the technology of choice where dry filters cannot handle gaseous pollutants, sticky/hygroscopic particles, high-moisture exhaust, or explosive conditions — common in chemical plants, acid pickling, plating shops, pharmaceutical reactors, and waste incinerators.

Aerotech's Air Pollution Control equipment includes venturi type wet scrubbers for sub-micron particulate capture, packed bed wet scrubbers for toxic gas neutralization (SO₂, HCl, NH₃, H₂S — 99.9% destruction efficiency), cyclonic spray tube wet scrubbers for combined particulate and gas treatment, packed bed dry adsorbers (activated carbon for VOC removal), and portable welding fume collectors with HEPA/PTFE filtration. Construction materials include SS 316L, FRP, polypropylene, and rubber-lined MS for maximum chemical resistance. Compliant with CPCB emission norms. Applications: chemical manufacturing, petrochemical refineries, pharmaceutical processing, metal finishing, fertilizer plants, food processing odour control, and marine diesel exhaust (IMO SOx regulations).
