A Guide To Bio-Filters
What are Bio-Filters?
Biofilters effectively cleanse the air of odours and other volatile compounds like ammonia, hydrogen sulfide, and aerosols. It manages gas emissions from mechanically ventilated chemical and manufacturing facilities. The microorganisms embedded on its surface metabolize the air pollutants, thereby producing energy, biomass, carbon dioxide, and water. Biofilters consist of a ventilator, filtered bed, humidifier, air distributor, and a control panel.
How are bio-filters unique from regular filters?
Unlike the regular filters that separate and purify the contaminated liquids, biofilters have microorganisms that consume the pollutants. These filters are explicitly constructed to purify the air in the most innocuous way.
Where are Bio-Filters found?
Biofilters are usually found to purify air streams for the chemical, metallurgical, and manufacturing industries like paint industries, mining industries, wastewater treatment plants, (WWTP), etc.
Bed of the Biofilters:
Biofilters are diversely designed, appearing in various shapes and sizes. They can be compact or composite, depending on where the filter would be built. Commonly used flatbed biofilters have a media of about 1-foot-deep, and usual fans blow the air. However, the footprint of a flatbed biofilter is large, which brings us to the recent discovery of vertical biofilters. The vertical biofilters have a deep bed with a deeper media of about 6 to 8 feet with a comparatively smaller footprint. They are not very common because of their premium price. However, managing and upkeep is a low cost.
Cost of Biofilters:
The cost of the biofilters depend on the following:
- Media
- Ducting and Materials
- Labor
- Fan Replacements
There is a wide variety of biofilters for consumers. Owners of the industries can either opt for flatbed, economical, but high maintenance biofilters or premium, deep bed vertical biofilters that require zero to no maintenance.
Effectiveness of Biofilters
The biofiltration process has a very high and rigorous removal procedure of odors and volatile organic compounds (VOCs). Carefully built and well-managed biofilters remove odor up to 95% and ventilate air from buildings by breaking down the harmful gases.
Maintenance Challenges
The common problems that arise during the running and managing of biofilters are clogging of media, congestion of gas streams within the bed, and moisture resulting in the system failure. These issues can be solved by maintaining the pH of the media and time to time inspection of the system.
Advancement of Biofilters:
Biofilters were discovered for decades initially to purify the air by decomposing the pollutants using microorganisms. The process of biofiltration has advanced through research and development to the extent that it has become a useful tool to remove contaminants from the surface or groundwater, thereby enhancing the quality of wastewater and groundwater. Biofilters have become necessary to provide humans and our ecosystem with clean and fresh air to inhale and decontaminated water to drink and use.
