“…From laboratory studies, an optimal range of 25-36°C has been found by several authors (Visvanathan et al 1999;Park et al 2009;Ménard et al 2011). Most of the methanotrophs are mesophilic and their optimal temperatures are from 20 to 30°C (Humer and Lechner 1999).…”

“…Most of the methanotrophs are mesophilic and their optimal temperatures are from 20 to 30°C (Humer and Lechner 1999). However, by controlling parameters such as the bed porosity, the moisture content, the amount of stabilized organic matter and the transfer of O 2 , it is possible to maintain the microbial activity at temperatures under 10°C (Gebert et al 2003;Kettunen et al 2006;Ménard et al 2011). From field experiments, Einola et al (2008) reported CH 4 removal efficiencies varying from 0 to 22% for temperatures in the biofilter between 2-9°C while the removal increased to 96% with temperatures from 9 to 25°C.…”

Biofiltration of methane and trace gases from landfills: A review

et al. 2012

View full text Add to dashboard Cite

Concerns about biogas from landfills are reviewed in terms of biogas generation, composition, and elimination. Biogas is mainly composed of methane and carbon dioxide but it also contains a few hundred non-methane organic compounds. The solutions available to reduce its harmful effects on the environment and on human health are valorization as electricity or heat, flaring, or biofiltration. The main parameters affecting the biofiltration of methane are reviewed: temperature, moisture content, properties of the packing material, nutrient supply, oxygen requirements, formation of exopolysaccharides, and gas residence time. An analysis is performed on the co-metabolic properties and the inhibition interactions of the methane-degrading bacteria, methanotrophs.

“…These results are consistent with others previously obtained. Menard et al (2011) achieved the highest performance in the range of 31-34°C working with a biofilter packed with an inorganic material. Spokas and Bogner (2010), during their study focused on mitigation of CH 4 emissions in landfill soil biocovers, obtained the highest CH 4 removal rates in the range of 22-35°C.…”

Biofiltration of an air stream polluted with diffuse CH 4 concentrations of 0.19 % (v v −1 ) was carried out. These emissions can be encountered at different industrial facilities such as wastewater treatment plants and landfills. The effect of ammonium supplied in the nutrient solution was studied in a range from 0 to 1 g N-NH 4 + L −1 , taking account its effect on CH 4 removal efficiency (RE), CO 2 production, ammonium conversion and the occurrence of exopolymeric substances. Additional batch assays were performed in order to evaluate the most suitable pH and temperature ranges for the biomass used as inoculum. A conventional biofilter was operated along 225 days achieving maximum CH 4 elimination capacities of up to 11.2 g CH 4 m -3 h −1 , corresponding to REs of 62 %, using 0.52 g N L −1 of ammonia as nitrogen source in the nutrient solution and operating at an empty bed residence time of 4.4 min. CO 2 production values confirmed that most of this elimination was biological and not absorption into the liquid phase. The occurrence of instability periods resulted in a clear increase of the soluble microbial products (SMPs) contained in the liquid phase, especially in the protein fraction, which could be used as a monitoring tool to follow the stress conditions of the biofilter. Results indicate interesting links between the performance of the biofilter and the presence of extracellular polysaccharide and protein concentration in the liquid phase, with increasing concentrations detected when the process was not stable.

BACKGROUND: Biofiltration of methane is of particular interest to contribute to limiting the greenhouse gas effect of biogas emissions from landfills. The complexity of the biogas mixture from landfills has underlined the importance of the presence of non-methane organic compounds. The aim of this study was to determine the effect of toluene on the microkinetic and macrokinetic parameters of methane biodegradation using an inorganic filter bed. RESULTS:Two concentrations of toluene were tested, 0.7 and 3.4 gC m −3 , and compared with the case of methane biofiltration alone. The specific growth rates of methane decreased from 0.793 to 0.574 to 0.278 d −1 when the toluene concentration was increased from 0 to 0.7 to 3.4 gC m −3 , respectively. The maximum elimination capacity of methane decreased from 39.4 to 5.6 gC m −3 h −1 when toluene concentration was increased from 0 to 3.4 gC m −3 . The half-saturation constants decreased from 4.6 to 1.6 gC m −3 and from 4.6 to 0.7 gC m −3 , respectively. CONCLUSIONS: Results show that an inhibition occurred on methane biodegradation when toluene was introduced into the biofilter.
