“…Effluent total phosphrous instead of the surface area (A) of the support media (Suidan and Wang, 1985). Biofilm reactor operates through contact processes in which wastewater passes through a bed of biomass either as a biofilm attached on the fixed media or as a mass of suspended growth solids within the bed.…”

Hybrid integrated fixed film activated sludge is a promising process for the enhancement of nitrification, denitrification and phosphorus removal in conventional activated sludge systems that can be used for upgrading biological nutrient removal, particularly when they have space limitations or need modifications that will require large monetary expenses. In this research, successful implementation of hybrid integrated fixed film activated sludge process at temperate zone wastewater treatment facilities has been studied by the placement of fixed film media into aerobic, anaerobic and anoxic zones. The primary objective of this study was to investigate the incorporation of enhanced biological phosphorus removal into hybrid integrated fixed film activated sludge systems and study the interactions between the fixed biomass and the mixed liquor suspended solids with respect to substrate competition and nutrient removal efficiencies. A pilot-scale anaerobic-anoxic-oxic configuration system was used. The system was operated at different mean cell residence times and influent chemical oxygen demand/total phosphorus ratios and with split influent flows. The experimental results confirmed that enhanced biological phosphorus removal could be incorporated successfully into hybrid integrated fixed film activated sludge system, but the redistribution of biomass resulting from the integration of fixed film media and the competition of organic substrate between enhanced biological phosphorus removal and denitrification would affect performances. Also, kinetic analysis of the reactor with regarding to phosphorus removal has been studied with different kinetic models and consequently the modified Stover-Kincannon kinetic model has been chosen for modeling studies and experimental data analysis of the hybrid integrated fixed film activated sludge reactor.

“…The substrate flux was also discussed. Suidan and Wang [8] followed the single-substrate biofilm model proposed by Williamson and McCarty in 1976. However, they further described a simple algebraic relationship between substrate flux, substrate concentration in the bulk phase (or at the film surface), and the biofilm thickness.…”

A biofilm model with substrate inhibition is proposed for the activated sludge growing discs of rotating biological contactor (RBC); this model is different from the steady-state biofilm model based on the Monod assumption. Both deep and shallow types of biofilms are examined and discussed. The biofilm models based on both Monod and substrate inhibition (Haldane) assumptions are compared. In addition, the relationships between substrate utilization rate, biofilm thickness, and liquid phase substrate concentration are discussed. The influence order of the factors that affect the biofilm thickness is studied and discussed by combining the Taguchi method and grey relational analysis. In this work, a Taguchi orthogonal table is used to construct the series that is needed for grey relational analysis to determine the influence priority of the four parameters S(B), kX(f), K(s), and K(i).

“…These models were shown to match bench-scale experimental results only when the biokinetic parameters were chosen to fit observed data. Development of state-of-the-art models, which can provide comprehensive process understanding and prediction, is still needed for biofiltration systems similar to those models developed for attached growth systems used for wastewater treatment (Williamson and McCarty 1976a,b;Rittmann and McCarty 1980;Suidan and Wang 1985;Suidan, Rittman, and Traegner 1987;Rittmann and Manem 1992).…”
