Biofilters consist mainly of a bed of organic material, where the pollutants` biological decomposition occurs. The organic material serves as both a substrate and nutrient source for the growth of bacteria. The air passes through the bed at low velocity, allowing the filter to absorb the odorous compounds, which subsequently diffuse in the biofilm and degrade.

Biofilter Media: The nourishment source of bacteria

Depending on the application, different types and mixes can be applied.

Choosing the proper filter media or mixtures ensures the optimal operating conditions for metabolic activity, resulting in short start-up periods and high efficiency.

Dimtech offers filters that, besides odor abatement, maintain low operating pressure drop, good drainage, and long-lasting service time.

Selecting suitable biofilter media to ensure the efficient removal of pollutants is essential.

Take into account the type of pollutants and the media`s lifespan to avoid constant replacements and filter malfunctions.

Biofilter media that are used include:

Wood chips
Tree bark
Peat
Coconut fibers

Extensive range of biofilter arrangements

Dimtech offers a wide variety of tailor-made solutions, including:

Single or multi-stage biofilter with upstream biotrickling filters, pre-washers, or chemical scrubbers
Vertical arrangements. The vertical version of biofilters ensures a lower footprint compared to the traditional ones.
Compact container biofilter systems
Closed-type biofilters for better conditions regulation

Our engineering and design department can offer the optimal biofilter version or propose a custom-made solution according to the restrictions and needs of each case.
