Air treatment with industrial biofilters
Biofiltration represents an environmentally friendly and economical technology ideal for the treatment of industrial emissions containing volatile organic substances (VOCs) and odoriferous compounds. This technique takes advantage of bioremediation, a process that transforms polluting and malodorous organic compounds into harmless, odorless elements. The transformation takes place through an oxidation process carried out by specific aerobic and mesophilic microorganisms (bacteria, molds, fungi and yeasts), which are actively involved in the treatment.
What are biofilters used for?
In many cases, biofiltration is also more effective than other chemical-physical solutions, as the biological agents are able to recognize and act on the pollutants present, providing a cross-cutting and comprehensive action. The application of biofilters is particularly suitable in sectors such as the chemical industry, waste management, food and water treatment.
Coral, our industrial company specializing in the production and distribution of purification equipment, supplies industrial biofilters at its facilities in Turin, Milan, Bologna and Vicenza. These plants are designed to ensure complete and effective purification of working environments.
How biological air purification works
Natural, ecological and economical, the biological process of biofiltration finds a simple and effective application in all industrial sectors that release noxious and odor-causing organic substances into the air, making their abatement necessary. Decontamination takes place through a filter bed consisting of an organic matrix, typically composed of mechanically treated plant residues. Pollutants dissolve in the wet biofilm that lines the filter material, thus becoming accessible to naturally occurring microorganisms. The latter derive energy by oxidizing the compounds, rendering them odorless.
These microorganisms, require appropriate conditions in order to develop and perform their function effectively. Therefore, in order to ensure effective air treatment, it is necessary to maintain certain values for inlet air flow rate, pH, temperature, porosity and humidity of the filter bed, as well as the relative humidity of the inlet flow. Finally, the flow rates to be treated must not contain concentrations or substances incompatible with the viability of microorganisms.
When is biofiltration performed?
Biofiltration is particularly suitable for treating VOCs at low to medium concentrations, where chemical or physical processes are less convenient. In fact, biological oxidation carried out by aerobic microorganisms allows cross-sectional and efficient management of many organic substances, often superior to traditional technologies.
Key advantages of using biofilters
The use of these solutions is an advantageous choice from the point of view of both overall operating costs and environmental protection, as it allows pollutants to be degraded quickly and naturally. Other product benefits are:
- Eco-friendly and sustainable: reduced environmental impact through natural process
- Economical: low operating and maintenance costs
- High efficiency: emission reduction of more than 90%
- Versatile: applicable to a wide range of harmful organic substances
What makes Coral 's solutions perform so well are our years of experience, which have enabled us to thoroughly understand the business needs of companies in need of air biofilters in Lombardy, Emilia-Romagna, Veneto and Piedmont.
