Pérez, F. Álvarez-Hornos, K. Portune, C. Gabaldón] The removal of styrene was studied using two biofilters packed with peat and coconut fibre (BF1-P and BF2-C, respectively) and one biotrickling filter (BTF) packed with plastic rings. Two inoculation procedures were applied: an enriched culture with strain Pseudomonas putida CECT 324 for BFs and activated sludge from a municipal wastewater treatment plant for the BTF. Inlet loads (ILs) between 10 and 45gm−3h−1 and empty bed residence times (EBRTs) from 30 to 120s were applied. At inlet concentrations ranging between 200 and 400mgNm−3, removal efficiencies between 70% and 95% were obtained in the three bioreactors. Maximum elimination capacities (ECs) of 81 and 39gm−3h−1 were obtained for the BF1-P and BF2-C, respectively (IL of 173gm−3h−1 and EBRT of 60s in BF1-P; IL of 89gm−3h−1 and EBRT of 90s in BF2-C). A maximum EC of 52gm−3h−1 was obtained for the BTF (IL of 116gm−3h−1, EBRT of 45s). Problems regarding high pressure drop appeared in the peat BF, whereas drying episodes occurred in the coconut fibre BF. DGGE revealed that the pure culture used for BF inoculation was not detected by day 105. Although two different inoculation procedures were applied, similar styrene removal at the end of the experiments was observed. The use as inoculum of activated sludge from municipal wastewater treatment plant appears a more feasible option.
