Aerobic purification of the effluents produced in the olive mill wastewater biomethanation process

Abstract

A study of aerobic treatment in batch regime of the effluents produced in the olive mill wastewater biomethanation process was carried out. An 83% of effluents 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 (qmáx and K) were obtained from Michaelis- Menten model.
