What is a Chemical Scrubbing System?

A Chemical Scrubbing System (Wet Scrubber) is an advanced air pollution control technology used to treat air streams containing gases, liquid droplets, and solid particles. Using gas-liquid diffusion, the system absorbs harmful gases while also capturing dust and mist through impaction and cyclonic separation.

How does the AmerAir Chemical Scrubbing System Work?

AmerAir® Wet Scrubbers use a reliable multi-stage absorption process to remove pollutants from contaminated air streams.

1. Ventilation & Extraction

A heavy-duty exhaust fan collects contaminated air from sources such as sewage wet wells, screen channels, and industrial process vents, directing it into the scrubber system.

2. Multi-Stage Chemical Contact

The air enters the bottom of the scrubber housing and moves upward through a specialised packing bed. At the same time, an automated recirculation pump sprays a targeted scrubbing liquid containing specific chemical reagents downward from the top.

3. Gas Dissolution & Reaction

As the dirty air and chemical spray meet inside the packing media, the odorous gases instantly dissolve into the liquid phase and react with the chemical agents, neutralising the pollution. Depending on your site's target requirements, this treatment can be split into 1, 2, or 3 separate chemical stages to achieve a higher removal efficiency

4. Clean Air Discharge

The washed air passes through a high-efficiency Chevron-type mist eliminator at the top of the tower to drop out any remaining liquid droplets, discharging perfectly clean air safely into the atmosphere.

Target Industrial Applications in India

This heavy-duty wet scrubbing technology is highly recommended for harsh industrial environments across India, especially where multiple types of pollutants are mixed together in the air stream:

​

  • Municipal Sewage Infrastructure: High-capacity urban Sewage Treatment Plants (STPs), major pumping stations, collection wet wells, and raw screen houses.

  • Chemical & Pharmaceutical Manufacturing: Reactor ventilation lines, acid gas exhaust streams, and volatile chemical storage zones.

  • Fertilizer & Petrochemical Plants: Managing complex gaseous blends containing high levels of ammonia, acid gases, and chemical particulates.

  • Tanneries, Paper, & Textile ETPs: Handling heavy, mixed pollutant loads from primary wastewater treatment processes.

Proprietary Technology: AmerAir K-Rosette™ Packing

Traditional packed towers use thick, extended-surface packings that block airflow, create massive air resistance, and cause high energy losses. AmerAir® solves this by using the proprietary K-Rosette™ filamentous packing media

Sharp-Edged Filament Efficiency

K-Rosette features ribbons with a square cross-section. These sharp edges provide a significantly higher target efficiency for trapping liquid and solid particulates compared to standard round or spherical shapes.

Ultra-Low Power Consumption

The wide-open configuration allows air to move through freely without severe or sudden direction changes. This reduces gas stream deviation, keeping pressure drops and fan electricity bills to an absolute minimum.

No Clogging or Misdistribution

Large-orifice, low-pressure-drop nozzles combined with K-Rosette's open structure completely eliminate the risk of chemical liquid misdistribution or clogging inside the column bed.

High-Performance Hardware Components

Every AmerAir® chemical scrubber is built using highly durable materials designed to survive harsh chemical environments:

Premium GRP Construction

The scrubber housing towers are built using Glass Reinforced Plastic (GRP). GRP keeps the structural weight incredibly low, reduces operating costs, and delivers maximum interior and exterior corrosion resistance for an exceptionally long service life.

Automated Chemical Dosing Fleet

The system includes heavy-duty chemical storage tanks and automated chemical dosing pumps that automatically monitor and supply the exact volume of reagents needed to keep the scrubbing solution active.

Inline Water Softener

To prevent mineral scaling and hard-water buildup inside the internal spray nozzles, an integrated water softener cleans and prepares the incoming fresh make-up water.

Frequently Asked Questions

Q1: How does the AmerAir Chemical Scrubbing System achieve up to 99.99% odour removal efficiency?

The AmerAir Chemical Scrubbing System uses multi-stage counter-current packed towers where foul air flows upwards while chemical reagents are automatically sprayed downwards. This close gas-liquid contact quickly neutralises high concentrations of H₂S, NH₃, acid gases, and airborne particulates, achieving up to 99.99%+ removal efficiency.

​

  • Multi-Stage Processing:

    • Stage 1 (Acid Scrubbing): Uses acidic reagents to neutralise basic gases such as ammonia (NH₃) and amines.

    • Stage 2/3 (Caustic/Oxidising): Uses sodium hydroxide (NaOH) or sodium hypochlorite (NaOCl) to oxidise hydrogen sulfide (H₂S) and mercaptans into non-hazardous salts.

    • Mist Elimination: High-efficiency Chevron-type mist eliminators remove liquid droplets before the treated air is discharged.

Q2: What makes AmerAir K-Rosette™ packing media better than conventional scrubber packings?

AmerAir K-Rosette™ packing media has a filamentous, open structure with sharp-edged, square cross-sections. This design increases liquid-gas contact and particulate capture while reducing air resistance, helping prevent bed clogging and lowering fan energy consumption compared with conventional packing media.

​

  • Engineering Advantages:

    • Ultra-Low Pressure Drop: The open design reduces resistance to airflow, helping lower electricity consumption.

    • Clog-Resistant Operation: Used with large-orifice, low-pressure spray nozzles, it helps prevent uneven chemical distribution and solids build-up inside the scrubber tower.

Q3: What materials are used in AmerAir Chemical Scrubbers to resist acidic and corrosive gases?

AmerAir Chemical Scrubber towers are manufactured from high-grade Glass Reinforced Plastic (GRP/FRP) with specialised corrosion-resistant liners. This non-metallic construction withstands harsh chemical reactions, extreme pH changes, and outdoor weather conditions while providing a lightweight structure with a long service life.
