Air pollution control through biotrickling 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 micro organisms for the bio chemical 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 attractive and economical due to :

  • Lower chemical requirements
  • Less harmful byproducts which are easier to handle
  • No need for disposal of toxic waste or further treatment of the scrubbing liquid
  • Reduced treatment expenditure
  • Ease of operation

Conventionally Biofilter and Biotrickling Filter (BTF) are utilized as standard mode of process configuration. Bio Trickling filter, known as BTF is based on much simple operational principle. In the BTF, micro organisms responsible for the biodegradation of the target pollutants are immobilized on special inert material or packing which provides surface area and favorable environment for the growth of micro organisms on it. Polluted air is passed from the bottom which then comes in contact with the micro organisms causing biochemical reduction of the pollutants. The bed of inert material is trickled with water from top which provides nutrients for the optimal growth of the micro organism and also carries out the by products of the biochemical oxidation from the filter bed keeping the filter bed functioning well for continuous biodegradation

Levapor carriers based air pollution control through biotrickling filter are state of the 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 biotrickling 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 specific properties of Levapor carriers developed for BTF, the technology provide distinct advantages :

  • Smaller foot print
  • Better reduction efficiencies
  • Remarkable process stability

We at Levapor, provide our clients complete turn key solutions for their polluted air and gas requirement using our highly sophisticated BTF Technology covering each aspects of projects from piloting to commissioning for their requirement.
