Treatment of Olive Oil Mill Wastewater by Fenton's Reagent ...

Wastewater from olive oil mills has been treated by means of the Fe(II)/H2O2 system (Fenton's reagent). Typical operating variables such as reagent concentration (CH2O2 = 1.0−0.2 M; CFe(II) = 0.01−0.1 M) and temperature (T = 293−323 K) exerted a positive influence on the chemical oxygen demand and total carbon removal. The optimum working pH was found to be in the range 2.5−3.0.
