Abstract
This research studied the kinetic parameters of aerobic treatment of domestic wastewater in Thailand by
using real influent wastewater at Nhong Kham wastewater treatment plant. Influent wastewater was added with
non-fat milk to increase COD to the range of 10-200 mg/L. The experiments were performed with batch reactors.
The results showed that biomass growth yield (Y) was 0.298 mg-cell-COD/mg-COD. The ratio of non-
biodegradable COD to total COD was 0.259. Kinetic parameters were determined using a non-linear equation of
the Monod and statistical program. The maximum specific growth rate (Pm) was 8.77+1.73 per day and the half-
saturation coefficient (KS) was 15.81+4.79 mg/L. Kinetic parameters from this research were in the same range of
previous studies.
Keywords: Kinetic parameters, Domestic wastewater, Activated sludge process
