Biokinetic parameters were determined and they were as follows: half velocity constant = 285.3 mg/l; maximum substrate utilisation rate = 9.29 day ^–1; yield coefficient = 0.0225 mg volatile suspended solids produced/mg substrate consumed; endogenous decay coefficient = 0.0122 day^-1 and maximum specific growth rate = 0.21 day^-1. A maximum of 96.9% COD removal was observed at a F/M ratio of 1.0^-1.
