Biofiltration was used to eliminate volatile organic compounds from air streams in bench-scale reactors inoculated with an adapted consortium. Organic and inert supports were tested on 100 days of operation. The supports were: peat, vermiculite, a mixture of vermiculite and activated carbon, tree bark and, porous glass Rashig rings. A mixture of benzene, toluene and xylene vapors with a load of...
This study investigates the occurrence of all priority substances (n = 41) listed in the Water Framework Directive and additional substances (n = 47) in raw sewage, as well as the removal performance of lamella clarification and biofiltration techniques. Once the efficiency of both types of techniques has been assessed for typical wastewater parameters, the differences in each technique's abili...
to assess the microbiological status of a biofiltration system used to treat borehole water, filtermatrix samples were analyzed after staining for the presence of active biofilms using confocal laser scanningmicroscopy (clsm). clsm revealed the presence of biofilms on the filter matrix with actively metabolizingmicrobial cells present. thereafter, heterotrophs,manganese oxidizing bacteria (mob)...
