Abstract

Un système pour éliminer les composés indésirables dun air contaminé comprend un biofiltre possédant un système dintroduction dun matériau alcalin et une commande fondée sur la logique floue. Un contaminant, comme le sulfure dhydrogène, est éliminé de lair contaminé en faisant passer ledit air contaminé à travers le biofiltre.
