D. Garciacalderon et al., COMPARISON OF 3 GRANULAR SUPPORT MATERIALS FOR ANAEROBIC FLUIDIZED-BED SYSTEMS, Biotechnology letters, 18(6), 1996, pp. 731-736
Three different materials, kaolin, pozzolana and biolite (a material u
sed in a commercial anaerobic fluidized bed treatment process) when te
sted as supports for an anaerobic fluidized bed system had similar phy
sical and fluidization properties but behaved differently towards the
biomass hold-up. However, all three systems attained similar removal e
fficiency rates.
