The table olive and olive oil industries are prominent agro-industrial sectors, playing a vital
role in the economies of Mediterranean Basin nations. The properties and quantity of table
olive processing wastewater are contingent upon the olive variety and the techniques
employed during processing. Table olive production wastewater contains high chemical
oxygen demand, dissolved and total suspended solids, oils and refractory organic compounds
such as phenolic substances which are derived from olives and processing techniques. The
treatment efficiency of conventional treatment processes not sufficient to obtain the desired
discharged values to any water body. Therefore, advanced oxidation process is one of the
recommended options to achieve discharge values.
This study aims to treat table olive processing wastewater using the homogeneous Fenton
oxidation process. The experiment focused on Fenton process, examining specific factors
such as reaction time, the concentrations of ferrous ion and hydrogen peroxide. The Box-
Behnken statistical design method was employed to conduct experimental research. The
Fenton process achieved an optimal and chemical oxygen demand (COD) removal of 95 %,
color removal of 70 % and phenol removal of 20 %, The highest efficiency of COD was
achieved as 95 % with a dose of 3500 mg/L hydrogen peroxide and 350 mg/L iron at 27.5 min
reaction time. The results indicate that the homogeneous Fenton process is a viable advanced
oxidation method for treating table olive processing wastewater. The advantage of
homogeneous Fenton oxidation process is that easy application of real wastewater treatment
process, it can be easily adapted conventional chemical treatment unit or it can be used
instead of conventional chemical treatment process in treatment scheme.
