Polyphenols

Polyphenols represent a wide class of organic compounds characterised by oxidrylic group bound to an aromatic ring. Their presence makes agro-food wastewaters phytotoxic and not suitable to conventional biological oxidation because of the inhibition of the bacterial activity. In this work the oxidat

The possibility of olive mill wastewaters (OMW) treatment and concentration by membrane distillation has been investigated. The objective is to obtain pure water and a concentrate containing high amounts of polyphenols, which can be extracted later. Two types of commercial membranes, polytetrafluoro
