In this work the variation in the elimination capacity of a biofilter as a function of the gas flow and toluene concentration was studied. A bioreactor 0.75 m highÃ14.5 cm diameter was used, divided into three equal stages, using compost to support the microorganisms, and sea shells to control the pH.
