The Biofilter

Air purification that does not create special waste or pollutants.

Biofiltration is a process that allows for the non-selective removal of the volatile organic compounds present in a stream of air, while also addressing issues related to the dispersion of odors into the atmosphere.
The greatest advantage derived from the biochemical oxidation of organic compounds, a process that governs the removal dynamics, lies in the fact that the undesirable substances are not simply confined but rather biodegraded, that is transformed through bacterial digestion into different non-harmful substances that are no longer problematic at an olfactory level.
The biomass used as a filtering media has a longer lifespan than other filtering materials available today and, when exhausted, has reduced waste disposal costs due to its benign nature.


Biofilter and Biofiltration

The biofilter for air deodorization (Deodorizer) is a natural system for the reduction of odors and for air purification.
Contaminated air is conveyed into a pre-cleaning Scrubber where jets of water bring it to a constant level of humidity and remove particulates. Then it passes into an expansion chamber where it is dispersed across the media support slab, comes into contact with the active biofilter and slowly passes through the filter media allowing the biofilter bacteria to destroy the foul-smelling substances. The latter are thus transformed into odorless and non-polluting substances, such as water and carbon dioxide.

Odors (diffused emissions of foul-smelling substances) derive from multiple sources and each biofilter is tailor-designed to purify the air from the types and the concentrations of the detected odorous substances. The biofilters are thus suitable in both low-concentration (which can create discomfort) and high-concentration conditions (which can create potential health risks).

GRT DARMA is mindful of the environmental impact of odors. With its biofilters it ensures the reduction of odorous substances in an environmentally-friendly and less administratively burdensome way.
