GALLI ALDO biofilters are entirely conceived in PP with an external support structure in stainless steel.
The cover, where required, can be rigid in aluminum, single or double slope, or made as tensile structure.
The parts of the biofilter are pre-assembled in the company and then welded in place.


The air to be treated is filtered through porous organic material, also known as filter medium or biomass, which serves as a support and in part as nourishment for aerobic microorganisms.
The latter carry out a biochemical oxidation process on the organic pollutants.

Unlike other chemical or physical deodorization treatments, biofiltration results in eliminating the pollutants and not transferring it to another location.
