Conventional suspended biomass reactors (e.g. activated sludge systems), widely used for treating municipal and/or industrial wastewater, have the disadvantage of large area requirement and high surplus biomass production. This explains the great effort being made worldwide to find a replacement for conventional technologies, with innovative ones aimed at lower footprint, better operational flexibility and lower sludge production. In such a contest, the Water Research Institute (IRSA) of the ...

The WAEES Project aims at the installation of a propeller system designed to increase the flushing rate of the southernmost region of the Lake Como West Arm (the so-called First Basin) characterized by high residence time due to the absence of a natural outflow. The first phase of the project (2006-2007) saw IRSA-CNR and the Centre for Water Research (CWR) of the University of Western Australia jointly work with the Centro di Cultura Scientifica A. Volta (the project manager). WAEES developed a ...

AquaStress è un Progetto Integrato di ricerca, avviato nel Febbraio 2005 nell'ambito del VI Programma Quadro dell'Unione Europea e della durata di quattro anni, cui partecipano 35 Istituzioni (Enti di ricerca, Università, Organizzazioni non-governative) appartenenti a 17 nazioni europee e del bacino mediterraneo, Nord Africa incluso. Il progetto è coordinato dall'Istituto di Ricerca Sulle Acque del CNR. Il consorzio di partner è caratterizzato da un'elevata interdisciplinarità, con esperti ...

Object of the study The contamination of aquifers by chlorinated solvents, caused by their widespread use in industrial processes and their improper handling and disposal, is today a major problem. The pollution of water resources by organo-halogenated compounds, started during 50s and continued for several decades, and is common to all the industrialised countries, including Italy. For the Italian legislation the decontamination of the polluted site by the responsible of the pollution or, if ...

In Italy most of the drinking water comes from groundwater that, according to update surveys, are often polluted by organic chemicals such as chlorinated solvents and pesticides. These pollutants reach groundwater because of rainfalls, over irrigation and/or unauthorized disposals. The removal of such toxic and persistent pollutants at potabilization plants is achieved by specific treatments such as adsorption onto activated carbon or membrane filtration. However, these treatments are ...
