Biogas biodesulfurization in an anoxic biotrickling filter packed with open-pore polyurethane foam.
Biogas biodesulfurization by an anoxic biotrickling filter packed with open pore polyurethane foam at the laboratory scale (packed volume 2.4L) has been studied. The biotrickling system was operated for 620 days with biogas supplied continuously and two nitrate feeding regimes were tested (manual and programmed). Biomass immobilization was carried out under the manual nitrate feeding regime and...
متن کاملRemoval of ammonia by immobilized Nitrosomonas europaea in a biotrickling filter packed with polyurethane foam.
A biotrickling filter with Nitrosomonas europaea immobilized on polyurethane foam is proposed for treating ammonia contaminated air. The effect of the surface velocity of the recirculation medium, nitrite concentration, pH, empty bed residence time (EBRT) and ammonia inlet load on the NH(3) removal process was investigated. The total amount of biomass immobilized on the carrier was 3.29+/-0.52 ...
متن کاملLaboratory pilot scale study for H2S removal from biogas in an anoxic biotrickling filter.
The purpose of this laboratory pilot scale study at the Wastewater Technology Centre (WTC), Environment Canada, Burlington, ON was to investigate the anaerobic biological removal of H2S from biogas under real-time operating conditions. Biogas produced in a 538 litre pilot anaerobic digester was continuously fed into a 12 litre biotrickling filter containing plastic fibres as packing bed media. ...
متن کاملEnhanced Biofilm Attachment onto Polyurethane Foam, Packed-bed Biotrickling Filters for the Treatment of Odors
The selection of an adequate support medium where the biofilm is immobilized in a biotrickling filter is critical for the optimization of the pollutant removal capacity of the unit. Recent efforts have focused in the development of synthetic media possessing properties such as high interfacial contact area, low density, high rigidity, high void fraction or porosity, sufficient water retention c...
متن کاملPerformance of biotrickling filters packed with structured or cubic polyurethane sponges for VOC removal.
Two identical bench-scale biotrickling filters (BTFs), BTF 1 and BTF 2, were evaluated for toluene removal at various gas empty bed contact times (EBCTs) and organic loadings. BTF 1 and BTF 2 were packed with structured and cubic synthetic polyurethane sponges, respectively. At a constant toluene loading of 16 g/(m3.hr), toluene removal efficiencies decreased from 98.8% to 64.3% for BTF 1 and f...
