Development of a phenol degrading fluidized bed bioreactor for constant biomass holdup

Specific ATP and specific oxygen uptake rate in immobilized cell aggregates: Experimental results and theoretical analysis using a structured model of immobilized cell growth

“…It has been shown (Livingston and Chase, 1991) that biofilms growing immobilized in a TPALB can reach a constant thickness (␦), for given substrate loading and hydraulic conditions, when net biomass growth rate equals total biomass loss rate. Furthermore, even if rates of growth and loss are not equal, pseudo-steady states may exist, when the biofilm grows slowly relative to the time constants associated with changes in substrate and -compartment distributions in the biofilm.…”

Aerobic treatment of wastewaters in the inverse fluidised bed biofilm reactor

“…The maximum penetration depth of substrate into the biofilm of the mixed aerobic cultures used for wastewater treatment is 50-200 m [7]. The excessive growth of biomass on support media can lead to the channelling of bioparticles in fluidised bed since the biomass loading can increase to such an extent that the bioparticles began to be carried over from a reactor [2,8].…”

“…The FBBRs, in which the biomass is spontaneously fixed on particles, are among the most effective apparatuses used in wastewater treatment [1][2][3][4][5][6][7][8]. The large biofilm-liquid interfacial area, high interfacial velocities and good mass transfer characteristics are the main advantages of this type of reactors.…”

Steady state behaviour of three phase air lift bioreactors - an integrated model and experimental verification

“…Livingston and Chase 43 have shown experimentally that bio®lms growing immobilised in a TPALB can eventually reach a constant thickness (d), for a given substrate loading and hydraulic conditions, when net biomass growth rate equals total biomass loss rate. Theoretically, this steady state biomass loading on the support particles (for a given microbial species) could be determined if the hydraulic characteristics of the bioreactor, and the rate of substrate supply into the system are known.…”
