Biofilters and activated carbon

Biofilters

How do they work? In biofilters, the substances to be purified are absorbed by the soft, porous material that makes up the filter bed (bark, peat, etc.), they diffuse into the aqueous film that wets and/or humidifies the material and are thus made available to be biodegraded by the microorganisms present in the natural matrix of which the bed is made. Biological filtration processes involve the use of a broad spectrum of ubiquitous microorganisms (bacteria, fungi, yeasts), capable of metabolising most natural organic and inorganic compounds through biological reactions, oxidations, reductions and hydrolysis.

Activated carbon

Activated carbon adsorption columns are used for the abatement of odours and low concentrations of VOCs or solvents, through the adsorption of the pollutant contained in the gaseous emission to an adsorbent material that is periodically disposed of and replaced. With activated carbon treatment, the aeriform stream containing airborne organic pollutants is sucked in by one or more fans, downstream of which one or more filters may be installed. The spent carbon must be periodically extracted from the columns and sent for disposal or regeneration.
