Integrated processes: Photocatalysis (PC) + Pervaporation (PV)

F It has been demonstrated that the integration of Photocatalysis (PC) with a membrane separation process, i.e. Pervaporation (PV), is a very promising method to improve the efficiency of the detoxification of water streams containing organic pollutants at low

concentration. F The commercial

pervaporation

membranes

are

organophilic so that most of the organic compounds permeate preferentially with respect to water. F 4-Chlorophenol has been used as a probe molecule and the disappearance rate (transformation in HQ and BQ) was highly improved.1
