Biofilter Overview

Biofiltration is an air pollution control technology which utilizes microorganisms to biologically degrade odors and other volatile air pollutants contained in waste air streams. The microorganisms exist on the surface and in a thin water film surrounding the surface of the biofilter material. During the biofiltration process, the contaminated air is slowly pumped through the biofilter material. The pollutants are adsorbed by the filter material's surface, and absorbed into the water film. Simultaneously the microorganisms biologically consume i.e., metabolize the pollutants, producing energy, biomass, and metabolic end products, mainly CO2 and H2O. The biofiltration process results in a complete decomposition of the pollutants without creating hazardous byproducts. Biofilters are technical applications that use the biofiltration process to remove odorous compounds and other air pollutants like volatile organic compounds (VOC) from waste air.

Global Biofilter Market Analysis

The global biofilter market size was $2093.60 million in 2022 and is predicted to grow with a CAGR of 9.56%, by generating a revenue of $5112.15 million by 2032.

COVID-19 Impact on Global Biofilter Market

The pandemic led to disruptions in global supply chains, impacting the production and distribution of biofilter components and systems.
