Abstract
Biokinetic parameters for biological treatment byactivated sludge process of cassava meal processingwastewaters were investigated. The experiments werecarried out in three steps: Firstly, the flocculationand sedimentation methods were employed with aJar-test in order to change the effluent concentrationof organics from 14 000 to 2000 mg L-1 and alsoto remove suspended solids. The second step wasperformed with four PVC reactors for biokineticparameters studies. The parameters found were used insizing a reactor for biological degradation byactivated sludge process. At the end, the finaleffluent was submitted to a treatment with aluminumsalts and natural polyelectrolytes to remove fecalcoliforms, remaining turbidity, and suspended solids.The biokinetic parameters investigated were: substrateremoval rate, food to microorganisms ratio (F/M),endogenous respiration rate, oxygen utilized per mg ofCOD removed, specific growth rate, etc.
