El biogás es una fuente de energía renovable que presenta siloxanos que deben
eliminarse ya que dañan los equipos de combustión de biogás. La degradación
biológica constituye una alternativa de bajo coste e impacto ambiental
comparada con tecnologías convencionales. En este trabajo se compara el
rendimiento de eliminación de siloxanos a bajas concentraciones (~60 mg/m3)
bajo condiciones anóxicas en tres biofiltros percoladores con: anillos plásticos
(BTF-1), espuma de poliuretano (BTF-2) y mezcla de anillos plásticos y carbón
activo (80:20% v/v) (BTF-3); e inoculados con fango anaerobio. El BTF-3
presenta una eficacia de eliminación total del 90% respecto al 33 y 34% del
BTF-1 y BTF-2, siendo el L3 el siloxano con mayor eliminación en el estudio
(98%). El aumento en la velocidad de recirculación de líquido (BTF-1 y 2) y la
disminución del EBRT de 60 a 42 min (BTF-3) influyeron negativamente en el
rendimiento de eliminación.
Biogas is a renewable energy source with siloxanes that must be removed as
they damage biogas combustion equipment. Biological siloxanes removal is a
cost-effective and environmentally friendly alternative compared to
conventional technologies. This work compares the removal performance of
siloxanes at low concentrations (~60 mg/m3) under anoxic conditions in three
biotrickling filter with: plastic rings (BTF-1), polyurethane foam (BTF-2) and a
mixture of plastic rings and activated carbon (80:20% v/v) (BTF-3) as packing
materials; and inoculated with anaerobic sludge. BTF-3 shows a total removal
efficiency of 90% compared to 33 and 34% for BTF-1 and BTF-2, with L3 being
the siloxane with the highest removal in the study (98%). Increasing the liquid
recirculation rate (BTF-1 and 2) and decreasing the EBRT from 60 to 42 min
(BTF-3) had a negative influence on the removal efficiency.
