Operation
mode of a
biofiltration:
The
biofilter
contains
a media called biomass
containing the bacteria specifically placed during the start up of the
installation.
The
polluted air will go through this media, co-current or counter-current.
The pollutants will be absorbed and neutralized into the
biofilter.
The
enclosure of the
biofilter
can be made out of concrete (civil
engineering) or
plastic out of our design. We have several types of modular designs
(containers) in PPH or HDPE. There is different type of support of
biomass
(mineral or organic).
Depending
on the operating conditions, the
biofilter
can be preceded of a
scrubber
in
order to take away one first part of the pollutants and to place the
bacteria
in the best conditions and to have a good efficiency of the
installation.
This
process does not use any chemical but alive being, the bacteria. The
operating
conditions must be moderate: ambient temperature, continuous operation,
no
strong concentrations of pollutants.
