Background: Olive oil extraction in the world is considered an important economic activity . Environmental impacts of olive oil wastewater is related to the chemical contents and organic materials load that are resistant to biodegradation. Olive wastewater due to phenolic compounds, inhibitors, toxicity to microorganisms in municipal wastewater treatment units, unpleasant odor, high COD, high...

Background and purpose: Wastewater olive processing industries have significant amounts of organic compounds resistant to biodegradation which are hazardous if not treated and discharged to the environment. Advanced oxidation processes such as Fenton process have been considered to increase and improve the biological degradability of this type of wastewater. Current study aimed at investigating...
