Identification of humic acid-like and fulvic acid-like natural organic matter in river water using fluorescence spectroscopy
Identifying the extent of humic acid (HA)-like and fulvic acid (FA)-like natural organic matter (NOM) present in natural water is important to assess disinfection by-product formation and fouling potential during drinking water treatment applications. However, the unique fluorescence properties related to HA-like NOM is masked by the fluorescence signals of the more abundant FA-like NOM. For this ...

Recent Papers in Adsorption and Ion Exchange Processes
Italian drinking water treatment plants (DWTP) generally use chlorine-based chemicals to achieve the oxidation/disinfection phases of their treatment trains. The main problem related to the application of such disinfectants consists in the formation of disinfection by-products (DBPs) as a result of the reaction with organic substances in the water. Italian regulations set very strict limits for ...

Environmental benefits of reclaimed water: an economic assessment in the context of the Water Framework Directive
The European Water Framework Directive (WFD) prescribes that all water bodies in Europe should achieve ‘good ecological status’ (GES). Maintaining a certain water flow is a pre-condition for the achievement of GES in areas of water scarcity. In such areas, reclaimed waste water is seen as a promising measure to keep river flow at a sufficient level. The contingent valuation method is applied here ...
