respectively, under sub-mesophilic
and mesophilic condition. Moreover, soluble COD removal effi-
ciencies were 92% in sub-mesophilic and 96% in mesophilic while
CH4 yield values almost the same for both temperatures and substrate
utilization rate of mesophilic culture was almost two times
higher than sub-mesophilic. Experimental results from two studies
indicates that AMBBR has promising treatment capability
of high-strength dairy wastewater at various organic loading and
temperature ranges
