Odour Abatement via Biofiltration

Pure Air Solutions developed various Biofiltration is the removal and oxidation of malodorous organic gases and volatile organic compounds by micro-organism. Common uses include processing waste water, capturing harmful chemicals or silt from surface runoff, and microbiotic oxidation of contaminants in air.

Pure Air Solutions has extensive knowledge and experience in biofiltration. Our engineered biofilters, developed, designed and built since the 1990’s, have provided significant footprint reductions, reliable operations, low running costs and removal efficiencies of 95% and more. Small (> 2.000 m3/h) and very large airflows (> 200.000 m3/h) can be treated. Although for large airflow a large area (footprint) has typically been required, our systems have reduced this footprint to 30% - 50% compared with conventional biofilters.

Process control

Maintaining optimum conditions is the major operational requirement for a biofilter. Our systems are implemented as standard with process control, which can be extended with scada and telemetric support. Also the implementation of a roof enclosure is imperative to ensure maximum performance of the filter system and biomass lifetime. Open filters suffer the effects of rain and sun. Besides increase of pressure drop due to precipitation, excess drainage from the filter bed will occur, a potential source of wastewater. Sunshine on the other hand might dry the upper part of the bed making it ineffective and might result in the formation of cracks and consequently breakthroughs of untreated gas. When the conditions of an airflow are within the optimum range, we can provide solutions for preconditioning.

We supply three different types of biofilters and other technologies for Odour control and VOC control. Our biofilters have guaranteed efficiency calculation, are fully computerised and are available for practically any odour problem!

Industries employing our biofiltration technology include (e.g.):

  • food processing
  • pet food and fish feed plants
  • vegetable oil refineries
  • poultry and meat processing
  • rendering plants
  • off-gas from wastewater treatment facilities
  • fragrance & flavouring
