Abstract

The lack of freshwater of acceptable quality constitutes a major problem, especially in the arid and semi-arid regions of the European Union. Therefore, wastewater and effluents from wastewater treatment stations must be considered as additional water resources for reuse, following to appropriate treatment. The Environment Institute, in the framework of a Third-Parties-Work project and in cooperation with an Italian drinking water company, the Ente Autonomo del Flumendosa, Cagliari/Sardenia, developed a concept of non-conventional wastewater treatment. The recovery potential of each effluents and industrial wastewater depends upon a number of chemical parameters, to be assessed by chemical analysis first, and on-site recovery testing later. To this end, a mobile wastewater treatment unit (WTU) on van-basis has been developed and constructed. This unit combines crossflow membrane filtration for the removal of particles, colloidal matter and macromolecules, with catalyzed photo-oxydation using hydrogen peroxide, UV-irradiation and immobilized titanium dioxide catalyzer membranes and features a capacity of 100 L/h. The paper reports the results obtained during a comparative study, using the JRC-Ispra's laboratory facilities as a standard, applying both synthetic and real wastewater effluents. Model substances studied included phenols and chlorinated phenols, chlorinated solvents, polyvinyl alcohol and triazine herbicides. Additionally, real wastewaters from dairy stations and municipal effluents were tested.
