A process and system are disclosed for the biofiltration of volatile organic compounds. The process involved recirculating contaminated effluent gas through a biofilter (1), the biofilter (1) having an inlet (20), outlet (15) and micro-organism laden filter media bed (3). The filter media bed additionally having moisture retaining properties. This process has been effective in removing high levels of VOCs from effluent gas streams and also in removing VOCs from an effluent gas stream where the VOC levels and/or volumes of effluent gas vary over time.
L'invention concerne un procédé et un système pour effectuer la biofiltration de composés organiques volatils. Ce procédé consiste à faire recirculer l'effluent gazeux contaminé à travers un biofiltre (1) qui comprend une entrée (20), une sortie (15) ainsi qu'un lit de matériau filtrant (3) chargé de micro-organismes et présentant des propriétés de rétention d'humidité. Ce procédé permet d'éliminer efficacement de grandes quantités de composés organiques volatils présents dans des courants d'effluents gazeux, les quantités et/ou les volumes de ces composés organiques volatils variant dans le temps.
