If you are involved in production, you're required to use air pollution control equipment to meet EPA standards. In addition, the community you operate in becomes more sensitive to environmental issues. The right air pollution technology makes it possible for you to meet government requirements with minimal impact on production costs, and guards your reputation as a concerned corporate citizen.

When you confer with an air pollution equipment manufacturer, take into account the industry processes you participate in most, paying attention to byproducts such as airborne particulates, volatile organic compounds (VOCs) or even excess heat. Three main air pollution technologies can address any combination of emissions:

1. Carbon adsorption, usually by activated carbon that can be used, regenerated and reused;

2. Thermal oxidation that can take advantage of heat to destroy VOCs;

3. Condensation or precipitation to remove heat and condense contaminants from vapor to liquid form for easier removal and storage.


Action Steps
The best contacts and resources to help you get it done

Sift through carbon adsorption options in air quality equipment


Beyond just passively filtering particles from the air, carbon removes pollution when the particulates collect on its surface. Since the particulates adhere to the surface of the carbon, there's little chance they will break free and flow back into the air, compared to a passive filter system, like a surge of air blowing through, or a tear developing in the filter. You then can dispose of the carbon element, or remove the particulates and reuse the carbon.

I recommend: Thiel Air Technologies specializes in removing micron-level particulates from the air. MEGTEC Systems, Inc. offers steam regenerated carbon adsorption systems, and with three regional headquarters in the US, France and Singapore, can handle projects worldwide.

Turn up the heat on VOCs with thermal oxidation air emissions equipment


Add heat and oxygen to VOCs, and you're left with carbon dioxide and water. Depending on the VOCs involved, you need heat rather than a catalytic process to destroy the VOCs. Today's air pollution control technologies have a thermal efficiency of up to 97%, making them much more cost effective than they used to be.

I recommend: NESTEC, Inc. offers regenerative thermal oxidizers, which uses heat transfer technology for more efficient VOC conversion and lower costs. Ship & Shore offers regenerative and recuperative thermal oxidizers. Contact them for more information on installing a system.

Control emissions with air pollution control technology using condensation or precipitation


Condensation rapidly reduces heat, causing particles or VOCs to condense, making it easier to trap them. Electrostatic precipitation collects particles in an electric field. A strong, well-designed electric field can use far less energy than scrubbers, meaning you can use a smaller, less expensive unit to do the same amount of work.

I recommend: Air Process Systems, LLC produces an evaporative cooling system that you can combine with an electrostatic precipitator for better emissions control of any combustion process. Contact the sales rep nearest you for a consultation. Envitech, Inc. promotes its wet electrostatic precipitator as one of the most versatile air pollution control devices on the market as it is designed to be either a down-flow or up-flow, concentric, tube-type precipitator. Complete the project spec sheet to narrow down the right size and type of technology to control air pollution for your business.

Tips & Tactics
Helpful advice for making the most of this Guide

  • If you have the real estate, look for advances in biofiltration as a greener technology for air pollution control. Biofiltration removes VOCs using beds of compost or soil. Microorganisms convert the VOC to carbon dioxide and water. The key, however, is allowing enough space and air flow for the system to work effectively.
