In LIFE Hymemb project a hybrid PAC/MF (powdered activated carbon adsorption and ceramic microfiltration) prototype was developed for a 1.5-year field test in Alcantarilha water treatment plant (Algarve, Portugal) and to demonstrate the process effectiveness, reliability and efficiency against pharmaceuticals, pesticides, cyanotoxins, viruses and protozoan (oo)cysts in drinking water. PAC/MF combines a low-pressure membrane technology, microfiltration with ceramic membranes, emerging in Europe but not yet used in Portugal, with PAC adsorption, tailored to fit the intake water quality. This article summarizes the most relevant results of PAC/MF operation and treated water quality that support the answers to when and where using PAC/MF technology. LIFE Hymemb demonstration proved that, when in the presence of the above mentioned contaminants, this technology will ensure high effectiveness and reliability with superior water quality than conventional treatment with an energy consumption of 0.05 kW/m3 and an estimated total cost (investment and operation) of 0.08-0.12 €/m3 to treat 100000 m3/day.
