TYPE OF EQUIPMENT:
IThe biodesulf biofilter is used to treat gaseous effluents. Air entering the biofilter travels upward through the bed/support (organic particulate material coated with an aqueous “biofilm” in which the micro-organisms are present) while the contaminants present in the air are stripped and metabolized.
The contaminants are then transformed into water vapour, carbon dioxide and biomass through biological oxidation with the oxygen present in the air.
Through the use of appropriate materials (compost, bark, wood chips, etc.) the filter bed can last for several years. Correct operation of the biofilter requires maintaining the following parameters: temperature (>10°C), pH (as close to neutral as possible), humidity (to maintain the biofilm and hence the population of microbes) as well as nutrients and oxygen.
The humidity can be maintained through an biodesulf TW® scrubber/humidifier which not only saturates the air entering the biofilter (creating the optimal conditions) but also can be used as a pre-treatment stage to remove any contaminants which could damage the biofilter if they come into contact with it. Using an integrated scrubber-biofilter in series assures ideal operating conditions as air exiting the scrubber is saturated with humidity.
For this purpose, where a chemical pre-treatment is not necessary biodesulf can supply UHR® series humidifiers which are less expensive than the TW® scrubber but equally effective in humidifying the air.
Finally, it is necessary to ensure that the air is distributed evenly through the whole volume of the bed to facilitate the circulation of oxygen through the biofilm. Using a mixed support (for example, compost-bark) assures appropriate porosity of the filter.
