“…Inlet concentrations ranging between 50 and 1200 mg m -3 were applied and an average elimination capacity (EC) of 12 g m -3 h -1 with a maximum of 30 g m -3 h -1 was obtained. Dehghanzadeh et al (2005) used a biofilter packed with yard waste compost mixed with shredded hard plastic and observed a maximum EC of 45 g m -3 h -1 at an inlet load (IL) of 60 g m -3 h -1 and an empty bed residence time (EBRT) of 120 s. Novak et al (2008) reported a maximum EC of 11.3 g C m -3 h -1 at an IL of 18.6 g C m -3 h -1 in a BTF packed with polypropylene Pall rings working with an EBRT of 35s.…”

“…In recent decades, styrene removal by biofiltration has been studied at laboratory by using biofilters and biotrickling filters (Arnold et al, 1997;Dehghanzadeh et al, 2005;Novak et al, 2008;Sempere et al, 2011). Biotrickling filter (BTF), with an aqueous stream trickling through an inert packing material, provides advantages in comparison with conventional biofilter (BF) such as higher removal rates, lower energy consumption and smaller footprint requirements (Pérez et al, 2015).…”

The performance and feasibility of a pilot unit of biotrickling filter (BTF) for the treatment of industrial emissions polluted by styrene was investigated for one year at a fiber reinforced plastic industrial site. The pilot unit was packed with a structured material with a volume of 0.6 m 3. Monitoring results have shown successful treatment of the industrial styrene emissions working at empty bed residence times (EBRT) between 31 and 66 s. The best performance was obtained after 300 days when a more stable biofilm had been developed, obtaining the highest elimination capacity of 18.8 g m-3 h-1 (removal efficiency of 75.6%) working at 31 s of EBRT. In addition, a photocatalytic reactor was evaluated as pretreatment of the biological process, but results have shown very low capacity for improving the BTF performance due to catalyst deactivation. The economic feasibility of the BTF was evaluated. The total direct cost, excluding capital recovery, of the biotrickling filter technology was estimated in 0.71 € year-1 per Nm 3 h-1 of treated air whereas 2.27 € year-1 per Nm 3 h-1 was obtained for the regenerative catalytic oxidizer equipped with a zeolite pre-concentrator. Results show that this technology is economically and environmentally competitive in comparison with thermal treatment.

The research into kinetics of styrene biodegradation by bacterial strain Pseudomonas sp. E-93486 coming from VTT Culture Collection (Finland) was presented in this work. Microbial growth tests in the presence of styrene as the sole carbon and energy source were performed both in batch and continuous cultures. Batch experiments were conducted for initial concentration of styrene in the liquid phase changed in the range of 5–90 g m−3. The Haldane model was found to be the best to fit the kinetic data, and the estimated constants of the equation were: μm = 0.1188 h−1, KS = 5.984 mg l−1, and Ki = 156.6 mg l−1. The yield coefficient mean value for the batch culture was 0.72 gdry cells weight (gsubstrate)−1. The experiments conducted in a chemostat at various dilution rates (D = 0.035–0.1 h−1) made it possible to determine the value of the coefficient for maintenance metabolism md = 0.0165 h−1 and the maximum yield coefficient value . Chemostat experiments confirmed the high value of yield coefficient observed in the batch culture. The conducted experiments showed high activity of the examined strain in the styrene biodegradation process and a relatively low sensitivity to inhibition of its growth at higher concentrations of styrene in the solution. Such exceptional features of Pseudomonas sp. E-93486 make this bacterial strain the perfect candidate for technical applications.
