Treatments of wastewaters from olive oil mills by uv radiation and by combined ozone‐UV radiation

Abstract

The chemical oxidation of the organic matter in olive mill wastewaters by the advanced oxidation process ozone plus UV radiation is studied to evaluate the increase in degradation in relation to ozonation alone. Also, the effect of the UV radiation alone on the oxidation is established. The destruction of the organic material was followed by the disappearance of the chemical oxygen demand (COD), the total aromatic compounds and the total phenolics. An approximate kinetic study is developed, the apparent kinetic constants with respect to the phenolic compounds being determined in both processes, the single photochemical and the combined ozone‐UV radiation.
