Résumé / Abstract
Four inorganic packing materials (zeocarbon, porous celite, porous glass, zeolite) and a earthworm cast were compared with regard to the removal of ammonia in a biofilter inoculated with earthworm cast. Physical adsorption of ammonia on packing materials were negligible except zeocarbon (23.5 g-NH
3/kg), and cell immobilization capacity have similar values irrespective of packing materials. Pressure drops of the packed bed were in order of earthworm cast ≥ zeocarbon≥ zeolite porous glass ≃ porous. The maximum elimination capacity (g-N.kg
-1.d
-1) of ammonia, which were based on a unit volume of packing material, were in order of zeocarbon (526) earthworm cast (220) porous celite (93) > zeolite (68) > porous glass (53). By using kinetic analysis, the maximum removal rates (V
m) and the saturation constant (K
s) for ammonia were determined, and zeocarbon showed superior performance among the five materials.
