Media bed life is from three to five years. Biofilters may be installed as an in-ground filter bed basin or may be supplied as a modular package system. The selection is primarily based on the size of the installation and space limitations at the site. Biofilter Uses Biofilters are best suited for large scale, permanent installations where the contaminant level is low, applications for which complimentary technologies such as activated carbon adsorption and thermal combustion are inappropriate. Biofilters have been used successfully in diverse applications to control both odours and VOC emission.
New applications continue to be developed.
The capital cost of biofilter systems are comparable to those of alternate technologies such as air scrubbers and adsorption systems. Operating costs are minimal. There is no chemical or energy consumption in the process and minimal instrumentation and monitoring are required. Biorem Services Biorem Technologies Inc provides complete turnkey installation of biofilters for air emission control. The services include process development, including pilot plant operation if necessary, system engineering design, system installation and on-going process monitoring.
