Packed Bed Scrubber Systems For Air Pollution Control
A packed tower scrubber system removes harmful substances and odor from gases, expelling clean air into the atmosphere. Also known as a column bed, this type of system offers a cost-effective and sustainable way for businesses in wastewater, pharmaceutical, petrochemical, oil and gas, and other industries to minimize air pollution. MACH Engineering is a leading provider of compact, efficient packed bed scrubbers that offer quality performance with competitive capital costs.
What Packed Bed Scrubber Configurations Are Available?
We take extra care in considering your facility’s specifications to determine the best solution. Our team can configure packed bed scrubber systems for air pollution in multiple ways, based on your facility’s specifications:
- Horizontal packed bed scrubbers: Ideal where there’s not enough headroom or for rooftop applications where a low profile is desired. Gas flows in horizontally while the scrubbing liquid flows down. We can add several stages in one housing with individual pumps.
- Vertical packed bed scrubbers: More efficient and demand less space. Gas flows upward while liquids spray down on the media. The sprayed liquid absorbs the contaminants in the gas.
- Multistage air scrubbing system: Works best for maximum contaminant capture and removal. Multiple stages with different scrubbing solutions ensure the gas is effectively cleaned. A multistage system is a good option if you’re working with gas constituting multiple substances.

Features and Benefits of Packed Bed Scrubbers
Column bed systems have practical features that enhance workflow, optimize business space, and effectively control air pollution. Features may include:
- Wide range of packing media: To augment the packed tower scrubber system, choose from a variety of tower packing options, including Tri-Packs®, Pall Rings, MACH Hi-Rings and more.
- Small footprint: Scrubber systems take up little space while providing efficient gas absorption and contaminant removal. Our solutions can be retrofitted to smaller areas.
- Stand-alone or centralized: We provide the equipment you need to use the tower scrubber system as a stand-alone feature or to connect with a centralized system.
- Corrosion resistance: The systems feature a corrosion-resistant Air Movement and Control Association (AMCA)-rated fan on the outlet or inlet.
The benefits of using packed bed scrubbers include:
- Enhanced efficiency: Depending on the gas stream, users can tailor the liquid in the scrubber. As the gas contacts the scrubbing liquid, targeted pollutants are absorbed and removed from the gas stream at high efficiency.
- Improved safety: Scrubbers can remove or reduce certain vapors, acid gases, odors, and water-soluble VOCs. Targeted hazardous substances are effectively captured or reduced, helping create a safer environment.
- Reduced liquid carryover: Mist eliminator systems get rid of entrained liquid droplets using loose fills, mist pads or chevrons.
- Increased absorption: Oxidation and neutralization treatments can increase chemical absorption, and our scrubber systems can control pH where needed.
Packed Bed Tower Materials
Our industrial wet scrubber systems are built for longevity and performance. MACH Engineering scrubber solutions are manufactured with the following materials:
- Titanium
- Mild steel and stainless steel
- Fiberglass reinforced plastic (FRP)
- Vinyl Ester Resin
- Polyethylene
- Polypropylene
- CPVC and PVC
We partner with leading, accredited suppliers who manufacture our packed tower scrubber systems using high-quality materials, industry expertise and a commitment to safety
Common Pollutants Removed
A packed bed scrubber removes several toxic substances from the contaminated gas as it moves up into the tower. Our packed bed scrubbers can remove the following:
- Chromic acid
- Formaldehyde
- Ethylene
- Acids and volatile organic compounds (VOCs)
- Soluble alcohols
- SO2
- BCI3 and BF3
- CL2, Br2 and F2
- Formic acid
- NH3
- HNO3
- HCN
- HBr
- HF
- HCI
- H2S
To quicken reaction time, you can add media packaging to the column to hold on to the scrubbing solution, maximizing the neutralization process. More reagents or makeup water are added at the bottom as the gas moves up and the scrubbing solution cleans the exhaust.
Applications of Packed Bed Scrubbers
Bed scrubbers are suitable for any industry that produces contaminated airflow. Use a MACH Engineering packed bed scrubber system for:
- Steel processing fumes.
- Biogas and landfill pollutants.
- Metal finishing contaminants.
- Wastewater treatment plant odors.
- Food processing odors.
- Acid fumes and gases.
- Chemical fumes and odors.
