Characterization of the biofiltration of methane emissions from municipal anaerobic effluents

A comparative assessment of the performance of fungal-bacterial and fungal biofilters for methane abatement

“…On the other hand, FB seems to be bioreaction limited except at low CH4 concentrations and low gas flow rates (0.19 L min -1 equivalent to an EBRT of 12.4 min), an observation supported by the influence of EBRT on CH4 EC (see Section 3.3). Gomez-Borraz et al [16] concluded that the performance of a compost bacteria-colonized biofilter was limited by the mass transport instead of by the bioreaction at a similar EBRT of 19 min and an inlet CH4 concentration of 21 g m -3 .…”

“…Mathematical modelling represents a powerful tool to optimize the design and operation of biological gas-treatment units. In this context, several reactive-internal transport/external transport based mathematical models have been reported to describe CH4 oxidation in biofilters inoculated with methanotrophic bacteria under isothermal conditions [15,16] and under non-isothermal conditions [17]. However, to our knowledge, mathematical models describing fungi-based methane biofilters are scarce, which limits the developments of these high-performance biofilters.…”

Recent progress on catalysts for catalytic oxidation of volatile organic compounds: a review

“…Biological degradation possesses the advantages of simple equipment, low operating cost, and less secondary pollution, which is constrained by the high selectivity of microorganisms. 30 Photocatalytic oxidation is a novel technology with the superiority of simple operation, mild reaction conditions, and low quantum efficiency which can be a fatal problem for this process. [31][32][33][34] A new treatment technology, plasma technology, was created by an extra electron field, which can form high-energy particles to decompose VOCs; however, it could produce many undesirable by-products despite low energy input.…”

Coupling a rotating biological contactor with an anaerobic baffled reactor for sustainable energy recovery from domestic wastewater

“…22,23,[32][33][34][35][36][37][38][39][40][41] Gómez-Borraz et al, (2017) and Huete et al, (2018) investigated oxidizing methane in a compost biofilter, and the maximum removal of dissolved methane achieved was 80%. 42,43 Similarly, a down-flow hanging sponge (DHS) removed 99% of dissolved methane. 44 Allegue et al (2020) used integrated fixed-film activated sludge (IFAS) to treat effluent of a UASB, with only 41% of dissolved methane oxidized.…”
