Title (EN) BIOFILTERING SYSTEM FOR TREATING AIR
(FR) SYSTEME DE FILTRAGE DE L'AIR
Abstract: front page image
(EN)A filter system for removing organic, odor-causing substances from air has a filter bed which comprises porous, particulate, non-compostable material and microorganisms capable of digesting the odor-causing substances. The particulate material of the bed is preferably lava rock, pumice or sandstone. A method of filtering air which contains organic, odor-causing substances, such as exhaust air from a process of thermophilic bacterial digestion of organic waste matter, comprises providing a filter bed of particulate, porous, non-compostable material, inoculating the filter bed with a culture of microorganisms and passing the air through the filter bed.
(FR)L'invention se rapporte à un système de filtrage conçu pour extraire de l'air des substances organiques malodorantes et comportant un lit de filtrage comprenant une matière poreuse, particulaire et non compostable ainsi que des micro-organismes capables de digérer lesdites substances malodorantes. La matière particulaire du lit est de préférence de la pierre de lave, de la pierre ponce ou du grès. L'invention se rapporte également à un procédé de filtrage de l'air contenant des substances organiques malodorantes, telles que de l'air d'échappement issu d'un processus de digestion bactérienne thermophile de déchets organiques, ledit procédé consistant à utiliser un lit de filtrage composé d'une matière particulaire, poreuse et non compostable, à inoculer le lit de filtrage en y introduisant une culture de micro-organismes et à faire passer l'air à travers ledit lit de filtrage.
