“…It should be noted that Monod-type kinetics is employed in Eq. (17) to represent microbial growth processes, as it is widely used to describe bacterial growth in cultures [64] and by extension, in various experimental systems of biofilm-coated porous media (for example: [65][66][67]). …”

Abstract. In this study, effects of hydraulic conditions including hydraulic loading rate and hydraulic saturation condition in fixed bed reactor with two different porous media were investigated by retention time distribution analysis. In terms of hydraulic modeling, models of tanks in series, plug flow and their mixed combination were employed to simulate breakthrough curves. Results indicated that number of tanks and dispersion coefficient instead of actual hydraulic volume were comparatively affected by water flow rate in both unsaturated and fully saturated hydraulic conditions. Moreover the latter condition contributed to higher actual hydraulic volume and lower number of tanks, and hydraulic saturation condition impacted the selection of support media as well.

“…This first step aims at determining hydraulic parameters like number of tanks in series, type of tanks (plug flow or perfectly mixed), average retention time, dead volume, recycle ratio and actual volume of the reactor. These parameters are then implemented in GPS-X software to simulate biodegradation processes (Zeng et al, 2013b). The biokinetic model chosen in GPS-X is a 2-step nitrogen model based on ASM in a biofilm reactor with biofilm diffusion fraction for substrates (Vigne et al, 2010).…”
