Clean Air Systems

Carbon Scrubbers

Carbon adsorption technology consists of moving contaminated air through a packed bed of activated carbon that adsorbs contaminants and discharges clean air. Effective and simple in principal of operation, carbon scrubbers are the mainstay of commercial and municipal odor/VOC mitigation.  Afras Air designs and manufactures carbon adsorption systems to custom fit the needs and specific requirements of each application.

Extended Carbon Lifespan

The most significant operational cost of carbon adsorption systems is activated carbon. At Afras Air numerous design optimizations and two patented technologies result in up to a 50% extension of activated carbon lifespan compared with traditional systems. The net result is  dramatic cost savings to our customers, and a reduction in hidden and environmental costs associated with the frequency of carbon change-outs. Afras Air continues to innovate and find new ways to optimize and deliver long term cost savings to our customers. 

BTF Systems

Biotrickling filtration (BTF) is widely used for the efficient control of noxious H2S produced in industrial and municipal wastewater treatment processes. BTF systems operate by moving odor laden air (typically H2S) through a bacterial biofilm immobilized on any one of several varieties of  media. Sulfer oxidizing bacteria in the biofilm oxidize H2S to sulfate which is subsequently washed from the system.  Afras Air designs,optimizes and manufactures BTF systems to meet the unique demands of industrial and municipal treatment processes. 

Afras BTF media

The choice of filtration media is critical to the operation, efficiency and economy of BTF systems. Afras Air’s BTF media has been optimized to maximize the surface area for biofilm immobilization without the pressure drop associated with other high surface area media choices. Our BTF media is ultra durable, lightweight and easy to install. Contact us for more information.
