Abstract

Four hybirdized anaerobic baffled reactors (HABRs) were constructed each with a total volume of 800 liters and consists of four compartments. The plastic media and gravel were used with the specific surface area of 100 and 80 m2/m3respectively. All the reactors in the pilot plant were used to examine the effect of transient and step hydraulic shock loads on reactor performance in terms of PH and COD, SS removal responses to hydraulic shocks in each compartment. The average influent COD and SS concentrations were about 300 and 175 mg/l respectively. The reactors were operated at three baseline conditions, hydrulic retention time (HRT) = 3.5, 2.5 and 1.5 days. At each baseline condition the reactors were subjected to three shocks with a duration of six hours per shock, However, the effect of decreasing HRTs coupled with increasing the organic loading rates (OLR) is more severe and its effects are more complex.. The HABR was found to be stable when subjected to large transient hydraulic shock loads for 6 hours and while biomass loss was substantial, it recovered to baseline conditions and performance after about 9 hours. The best results was observed in the reactor with plactic media compared with with other reactors. The compartmentalized structure of the HABR together with the presence of media prevents much of the biomass being washed out or exposed to low pHs during step hydraulic shock loads.
