Monroe’s Air Pollution Control Systems & Equipment
Air Pollution Control Applications & Process Experience
Monroe Environmental has extensive experience with a wide variety of applications and processes for air pollution control. Click on a pollutant below to learn more about our approach to treating these contaminants.
Monroe has extensive experience capturing and neutralizing acid and alkaline gasses using the following technologies:
- Packed Bed Scrubbers & Absorbers
- Venturi Scrubbers
- Multi-Stage Wet Scrubbing Systems
- Carbon Adsorbers
Common pollutants treated include sulfur dioxide (SO2), hydrogen sulfide (H2S), hydrogen chloride (HCl), hydrogen flouride (HF), ethylene oxide (EtO), and ammonia (NH3).
Physical characteristics (wet, dry, sticky, solid, liquid, vapor, etc.) as well as chemical make-up of the particulate must always be evaluated in order to determine the most appropriate control equipment. Additional factors such as application, moisture content of the air/gas stream, regulatory requirements, and other pollutants present also significantly impact control device selection.
Recent changes to many emissions regulations have made PM2.5, sub-micron, and condensable particulates of special consideration. Monroe Environmental has the experience and expertise to meet these demanding requirements.
Monroe offers the following systems for particulate matter collection, filtration, and reduction:
- Dry Dust Collectors (Cartridge/Bag)
- Mist Collectors & Eliminators
- Fiber Bed Collectors
- Venturi Wet Scrubbers
- Multi-Stage Scrubbing Systems
- Quencher/Condensers
- Wet Electrostatic Precipitators (WESPs)
Explosive Dust Collection is a specialized area of particulate matter collection. Monroe has decades of experience controlling explosive dust. Check out our Explosive Dust Collection page to learn more.
Temperature adjustment of the gas stream is often a required step to ensure that condensables are removed prior to coalescing and filtration with media or electrostatic charge.
Monroe’s systems and equipment include:
Volatile Organic Compounds (VOCs) as well odorous compounds can be removed from process exhaust via wet scrubbing, dry adsorption, and thermal destruction. Each of these has pros and cons which must be weighed according to a variety of factors including pollutant loading, gas volume, utility costs, and others. Monroe Environmental can assist with evaluating the process specifics and recommend the most cost-effective solution.
Our systems and equipment include:

Mist Collection covers an expansive list of applications from machining, parts washing, cold rolling and hot temper mills, food processing, and many others. Monroe Environmental is a worldwide leader in mist collection, with a variety of designs to suit any application.
Our systems and technologies include:
Dust Collection is a very common air pollution control application that encompasses collection, filtration, separation, and recovery of dry, wet, and explosive particulates. There are a variety of dry filter media options including bags, cartridges, box filters, metal screens, and countless others that should be carefully selected based on application specifics. Wet Collection is also common for wet, sticky, and waxy particulate and can reduce lifetime operating costs by eliminating filter media. Explosive dust can be handled with either wet or dry collection.
