The development of effective and simple methods for treating wastewater is a challenging task for environmental engineers. In this chapter, a novel modified anaerobic hybridized baffled (MAHB) bioreactor, which is a combination of regular suspended-growth and fixed biofilm systems together with the modification of baffled-reactor configurations, was proven to be a modest bioreactor for wastewater treatment rather than the commercial anaerobic baffled reactor (ABR). The significant advantages of this bioreactor were its ability to nearly realize the multi-stages anaerobic theory, allowing different bacterial groups to develop under more favourable conditions, reduced sludge bed expansion, no special gas or sludge separation required, and high stability to organic and toxic shock loads. The compartmentalization of this bioreactor results in a buffering zone between the primary acidification zone and active methanogenesis zone, and provided the strong ability to resist shock loads whic...

Anaerobic wastewater treatment is receiving renewed interest because it offers a means to treat wastewater with lower energy investment. Because the microorganisms involved grow more slowly, such systems require clever design so that the microbes have sufficient time with the substrate to complete treatment without requiring enormous reactor volumes. The anaerobic baffled reactor has inherent advantages over single compartment reactors due to its circulation pattern that approaches a plug flow reactor. The physical configuration of the anaerobic baffled reactor enables significant modifications to be made; resulting in a reactor which is proficient of treating complex wastewaters which presently require only one unit, ultimately significant reducing capital costs. This paper also concerns about mechanism, kinetic and hydrodynamic studies of anaerobic digestion for future application of the anaerobic baffled reactor for wastewater treatment.

An anaerobic baffled reactor (ABR) (3 000 L) was investigated for on-site sanitation for low-income communities. The eight-compartment reactor allows high solids retention with high treatment rates, and is stable to organic and hydraulic shock loads. The reactor was fed with raw domestic wastewater from a middle-income community at a wastewater treatment facility. A previous study on the pilot-scale ABR, operated at an average HRT of 22 h, revealed that there was no phase separation in the reactor, due to the slow rate of hydrolysis. Hydrolytic and acidogenic bacteria were located in all compartments of the reactor, with a few scavenging methanogens in the first few compartments. The objective of this study was to therefore investigate the hypothesis that a better spatial separation might occur at a longer HRT. When the HRT was increased to 40-44 h, a partial separation of acidogenic and methanogenic phases was observed, using scanning electron microscopy (SEM). Scavenging by micro-...
