Biofiltration

Biofiltration is a process for reducing the polluting substances in the air which uses biological oxidation: the contaminated air is lead through a means which contains microorganisms capable of decomposing the polluting substances using them as a nutrition source.
Basically the system permits to obtain the same results of combustion, with the exception that oxidation of volatile organic mixtures with carbon dioxide is not done thermally but biologically; if the mixtures contain sulphur, nitrogen or chlorine, then the sub-products of the oxidation are mineral salts. These applications are economically more advantageous than the combustion systems, both in terms of construction and maintenance, but they require a good design to be capable of showing an optimal utilisation.

With Eolo it is possible to realise a perforated floor thanks to the nozzles which allow the regular and uniform distribution of air. Through the air cavity which is created thanks to Eolo and its output nozzles, the distribution of air is uniform over the whole surface of the filtering bed.
