Abstract
An upflow velocity of 0.21 m h(-1) was optimal to minimize the effect of or ganic shocks (from 6 to 30 kg COD m(-3) d(-1)) when operating an upflow ana erobic filter for the treatment of an oleic acid-based effluent (50% w/v CO D). This value represented the transition between a mass transfer controlle d regime and a kinetic regime. Under hydraulic shock loads, an increase in upflow velocity from 0.3 to 0.4 m h(-1) decreased the removal efficiency fr om 68 to 51%.
