Abstract


A study of aerobic treatment in batch regime of condensed water from thermal concentration process of olive mill wastewater was carried out.
An 80% of wastewater organic substances was removal after the third day of fermentation.
The substrate removal rate follows a zero-order kinetic for high concentrations, and a first-order kinetic for low organic matter concentration, during the last days of fermentation.
The kinetic parameters (qmax and Ks) were obtain by Michaelis- Menten model.

Keywords
