A crucial variable for the successful operation in biofilters is the selection, acclimation and activation of the microorganisms that will degrade the contaminants. The purpose of this study is to apply a procedure for the acclimation and activation of biomass of different origin (with or without an additional carbon source). In order to obtain adapted microorganisms, sludge was collected from one wastewater treatment facility and from a synthetic resin-producing industry. Two different sediments samples were also collected from two rivers that pass through industrial areas. After sedimentation of the solid phase of each sludge, the liquid phase was transferred into glass bottles for biomass activation. This activation has been carried out with and without glucose in different doses and the biomass has been acclimated to an organic contaminant (toluene) by adding small amounts of the compound with a syringe. The contaminant consumption rate has been determined by measuring its amount at the beginning of each addition and subsequent to 24 hours. The adapted biomass will be used to inoculate a future biofilter for treating toluene.
