Air pollution control through bio trickling filter treatment of pollutants like H2S, VOC, Mercaptans, etc present in the polluted air or gas is widely recognized and acceptable technology for air purification. The process utilizes microorganisms for the biochemical oxidation of the pollutants present in the air to less harmful byproducts which are easier to handle and less harmful to the receiving environment. Thus, compared to conventional chemical scrubbers used for air purification, biological solutions are much more attractive and economical due to:
- Lower chemical requirements
- Less harmful byproducts that are easier to handle
- No need for the disposal of toxic waste or further treatment of the scrubbing liquid
- Reduced treatment expenditure
- Ease of operation
Conventionally Biofilter and Biotrickling Filters (BTF) are utilized as standard modes of process configuration. Bio Trickling filter, known as BTF is based on much simple operational principle. In the BTF, microorganisms responsible for the biodegradation of the target pollutants are immobilized on special inert material or packing which provides surface area and a favorable environment for the growth of microorganisms on it. Polluted air is passed from the bottom which then comes in contact with the microorganisms causing biochemical reduction of the pollutants. The bed of inert material is trickled with water from the top which provides nutrients for the optimal growth of the microorganism and also carries out the byproducts of the biochemical oxidation from the filter bed keeping the filter bed functioning well for continuous biodegradation.
Levapor carriers-based air pollution control through bio-trickling filters are state-of-a-art technology developed after years of research and innovation for the reduction of different biodegradable pollutants from the air and gas. Levapor air pollution control through bio-trickling filter solutions can be applied for the reduction of:
- H2S
- VOC
- Mercaptans
- DMS, Alcohols, Aldehydes, Ketons, Fatty Acids and their Esters, Phenols, Styrene, Nepthalene and its Odor
- Heterocyclic Sulfur compounds, CS2
- Chlorine-laden components: Dichloromethane, 1,2-dichloroethane, Chlorophenol
- Trichloroethane, Monovinylchloride
- Ammonia, Amines, NOx
Due to the specific properties of Levapor carriers developed for BTF, the technology provides distinct advantages:
- Smaller footprint
- Better reduction efficiencies
- Remarkable process stability
We at Levapor, provide our clients with complete turnkey solutions for their polluted air and gas requirements using our highly sophisticated BTF Technology covering each aspect of projects from piloting to commissioning for their requirements.
