“…These loadings are low compared with the OLR of 30 kg COD /m 3 /d that is possible with this type of reactor and reported by various authors [39,40]. However, animal manure is not commonly used as a substrate for this reactor in full-scale applications and can be difficult due to low organic loads and high nitrogen concentrations [17,41,42]. This issue can be addressed by co-digesting animal manure with industrial wastewater and residues, such as tofu whey, a protein-rich residue resulting from the production of tofu, or wastewater from starch production [43,44].…”

“…The previous qualitative description of the relation between MPR and OLR was extended by linear fitting. Table 5 present linear regression models where the OLR is the main influencing parameter of AD in EGSB and FB reactors [17,42], and the MPR is the response variable. Yu et al [55] and Jafarzadeh et al [33] reported similar observations for the AD of soybean wastewater with an anaerobic filter and the AD of petrochemical wastewaters in a hybrid UASB/anaerobic filter.…”

Anaerobic digestion of animal manure is a potential bioenergy resource that avoids greenhouse gas emissions. However, the conventional approach is to use continuously stirred tank reactors (CSTRs) with hydraulic retention times (HRTs) of greater than 30 d. Reactors with biomass retention were investigated in this study in order to increase the efficiency of the digestion process. Filtered pig slurry was used as a substrate in an expanded granular sludge bed (EGSB) reactor and fixed-bed (FB) reactor. The highest degradation efficiency (ηCOD) and methane yield (MY) relative to the chemical oxygen demand (COD) were observed at the minimum loading rates, with MY = 262 L/kgCOD and ηCOD = 73% for the FB reactor and MY = 292 L/kgCOD and ηCOD = 76% for the EGSB reactor. The highest daily methane production rate (MPR) was observed at the maximum loading rate, with MPR = 3.00 m3/m3/d at HRT = 2 d for the FB reactor and MPR = 2.16 m3/m3/d at HRT = 3 d for the EGSB reactor. For both reactors, a reduction in HRT was possible compared to conventionally driven CSTRs, with the EGSB reactor offering a higher methane yield and production rate at a shorter HRT.
