“…The packing media was supported inside the reactor with the help of a perforated plate. The packing media was placed in 20 % of the total volume of the reactor (Wu et al, 2000). The schematic diagram of the reactors is shown in Figure 1.…”

“…Later, the absorbance of the sample was checked in UV spectrophotometer and the concentration of tracer in the sample was obtained using the standard dye calibration curve. The method adopted was similar to that followed by Wu et al, (2000), and the Noguera and Perez (2007). Another dispersion index viz., Morril Dispersion Index (MDI) was used for calculation of volumetric efficiency, short circuiting, average retention time and mean retention time.…”

“…Nevertheless, there is a remaining problem for this reactor. Most nutrients were often found to be completely removed before entering the packed zone, resulting in limited nutrient availability for attached microbial growth 7,8,9,10,11,12 . As such, a long start up period is observed.…”

“…Moreover, high substrate removal efficiencies would be achieved in anaerobic reactors with short hydraulic retention time (HRT) and high organic loading rate (OLR) . One of the most efficient and quite flexible designs available is an anaerobic hybrid (AH) reactor which combines advantages of both anaerobic filter (AF) and up-flow anaerobic sludge blanket (UASB) designs (Chang ,1989;Hawkes et al, 1995;Wu et al, 2000;Mahmoud et al, 2009). The presence of polyurethane media in the upper portion of AH reactor, in addition to its physical role for biomass retention, also exerts some biological activity which contributes to chemical oxygen demand (COD) reduction in a zone where generally active biomass is lacking in a calssical UASB reactor (Elmitwalli et al, 1999;).…”
