Remediation of olive mill waste water: a combined process of physico-chemical and encapsulated biomass

The environmental impacts caused by Olive Mill Wastewater (OMWW) have become significant worldwide concerns for both developing and developed countries involve in olive oil production. This study propose a feasible technological pre-treatment system based on ozonation technology, integrated biological treatment of fixed biomass, reducing phenols and organic matter of OMWW, in a way which improve its quality before the conventional treatment at the wastewater treatment plant, thus continue to a safe release into the environment. As a synthetic phenol model, results of Tannic acid degradation are presented in this assay, showing success of approximately 80% in total phenol removal.
