Another method is the upflow anaerobic sludge blanket illustrated in Figure 26.8. Here the sludge is contacted by upward flow of the feed at a velocity such that the sludge is not carried out of the top of the digester.

A third type of reactor system is the upflow anaerobic sludge blanket (UASB) reactor system. The UASB is a continuous-flow system that maintains a dense flocculated biomass that is granular. The waste-water passes through this dense sludge blanket to achieve desired treatment efficiency. The UASB, anaerobic filter, and fluidized-bed systems have all been applied successfully to treat a variety of industrial waste streams. Table 22-44 summarizes some of the applications of these treatment technologies. 

Several effluent treatment options were evaluated at the AIPM paper mill in Herada, Israel, (Table 35.7). Stahl et al. [119] studied anaerobic treatment by an upflow anaerobic sludge blanket internal circulation bioreactor (UASB-IC, from Paques) before aerobic treatment. The effluent from the UASB-IC was then further treated by an aerobic activated-sludge-pilot (ASP,...
