The gaseous effluent biofiltration process developed by TECNIA can be used to treat and control hazardous air pollutants (HAPs), volatile and halogenated organic compounds (VOCs and HOCs), monocyclic and polycyclic aromatic hydrocarbons (MAHs and PAHs) and certain alcohols. It is also useful for odour control, such as odour proceeding from WWTPs (Wastewater Treatment Plants), among many other sources.

The use of biofiltration to treat gaseous effluents offers the advantage of no troublesome byproducts, wastewater or dust being produced. The end-products of the process are carbon dioxide (CO2), water vapour (H2O) and a residual fraction of the components being removed, which varies according to the degree of removal pretended.

Another technology, a vapor phase adsorption system developed by TECNIA, was especially designed to remove gaseous contaminants, including Furans and Dioxins, Hydrogen Sulphide, Hydrogen Chloride, Mercaptans and Ammonia, thus providing an high effective treatment and control technology, both in individual or in set with the biofiltration technology. TECNIA offers a Deep-Bed design that may be used as part of a new pollution control train or system, or as a retro-fit unit to be added to an existing system.
