BIOFILTRATION OF AIR
Biofiltration is a relatively new pollution control
It is the purification of air using biofilters.
It is an attractive technique for the elimination of
ADVANTAGES OF BIOFILTRATION
Lower operation cost ,lower capital cost, low chemical usage, and no combustion source.
Minimize space requirements and multiple units can be run in parallel.
Biofiltration is versatile enough to treat odour, toxic compounds, and VOCs. The treatment efficiency is above 90%.
Biofiltration unit can be designed as any shape, size or as an open field with the piping.
Different media, microbes and operating conditions can be used to tailor a biofilter system for many emission points.
DISADVANTAGES OF BIOFILTRATION
Biofiltration cannot successfully treat some organic compounds.
Contaminant sources with high chemical emissions would require large biofilter units or open areas to install a biofiltration system.
Sources with emissions that fluctuate severely or produce large spikes can be detrimental to the of a biofilterâ„¢s microbial population and overall performance.
Acclimation periods for the microbial population may take weeks or even months, especially for VOC treatment.

The experiment results showed that the biofilter as competent ability in
eliminating rapeseed oil smoke over an extended period of time.
Its removal efficiency is greater than 97%.
Capita cost and operating cost were very low.
