Biofiltration is a pollution control technique using a bioreactor containing living material to capture and biologically degrade pollutants. Common uses include processing waste water , capturing harmful chemicals or silt from surface runoff , and microbiotic oxidation of contaminants in air.

The biofiltration technique is cost-effective, simple, biocompatible, sustainable, and eco-friendly compared to conventional techniques. This review article provides deep insight into biofiltration technologies engaged in the removal of volatile organic compounds and heavy metals in the wastewater treatment process.

Biofiltration is defined as a filtration process where the filter medium comprises porous material (e.g., sand, granulated active carbon (GAC), or a synthetic carrier material), which is colonized by indigenous microbial communities and where the microorganisms perform at least one of the essential treatment functions of the process.

A biofilm of indigenous microorganisms fixed on solid surface, called biofilter, is an eco-friendly and economic technique for removal of pollutants and pathogens.

Biofilters contain filter medium grains (e.g., sand, granular activated carbon) that are covered with biofilms. The biofilm activities break down nutrients (e.g., nitrogen and...

Biofiltration is a new technology used to purify contaminated air evolved from volatile organic and inorganic compounds by involving microorganisms. It is a low cost technology gradually becoming popular due to simple operational and waste-removal efficiencies.

1997年6月1日 · Biofiltration is a biological air pollution control technology for volatile organic compounds (VOCs). This paper summarizes the fundamentals, design and operation, and application of the process. Biofiltration has been demonstrated to be an effective technology for VOCs from many industries.

2022年8月14日 · This review highlights the effectiveness of biofiltration for water treatment and for tertiary treatment of domestic and industrial wastewater. Treatment of water through biofiltration promotes the removal of assimilable organic carbon, micropollutants, and disinfection by products.

Biofiltration is a pollution technique which uses living material to capture biologically degradable pollutants. This biofilters are commonly used for processing waste water, capturing harmful chemicals and capturing contaminants from air [82].

Biofiltration is used to treats volatile organic and inorganic compounds (VOCs and VICs). This includes paint industries, oil and gas plants, petrochemicals and waste water treatment. But the use of biofilters is not limited to mass industrial processes or large businesses.
