    It has been demonstrated that high performance efficiency (more than 80 BOD destruction/o-cresol removal) is attained within a low reactor volume (D = 0.5 m L Sf = 1.2 m) at high capacities (as high as 82 000 L h − 1). Another interesting feature reported is that in these bioreactors the fractional substrate conversion (α) increases with increase in feed flow rate.
