“…Membrane fouling is known to affect solute rejection by RO membranes [14]. Therefore, the relationship between the extent of membrane fouling and Cs/Sr rejection was quantitatively investigated by adding 10 mg L −1 HA to the feed tank to produce organic fouling of the membrane.…”

“…Successful removals of radionuclides by membrane filtration have been reported in the literature [9][10][11][12]. In Spain, the full-scale RO treatment applied at the Sant Joan Despí Water Treatment Plant reduced both gross alpha and gross beta activities in drinking water by more than 90% [13,14]. RO tive contamination than the common conventional methods of ion exchange resins, chemical precipitation, coagulation, and adsorption in groundwater [15].…”

“…The similar results obtained in this previous study and our study indicate that the decontamination work carried out in front of the DCP factory have not affected the gross alpha activity. Due to the relatively high activity values that in some cases are close to or even higher than the legal value, an exhaustive control of the outgoing water samples is important in order to fulfil the normative requirements (Montaña et al, 2013). In this regard, it is important to remark that in the DWTP there are some efforts focused on the improvement of the water quality.…”

-In recent years, a decontamination project has been under way to remove the polluted sludge on the riverbed of the Ebro river, particularly in the area of Flix (Tarragona, Spain). This project started in 2011 and consists of the removal of the sludge and its treatment in a process that will eventually restore the river to its natural conditions. The sludge is a product of the historical dumping of contaminants by a chemical complex situated next to the river, and it contains a range of contaminants, such as heavy metals, semi-and volatile organic compounds, and radionuclides. Downstream of the complex, in the town of L'Ampolla, a drinking water treatment plant (DWTP) is located. This plant collects the water from the Ebro river and, after potabilisation, the plant supplies drinking water to the population of southern Catalonia. Due to the possible presence of radionuclides in the river water, it was considered important to monitor and control the radioactivity parameters regulated under current legislation for water consumption. For this reason, in this study, our aim is to evaluate if the decontamination work carried out in Flix has any effects on the radioactivity levels of both Ebro river and treated water, by means of the determination of gross alpha activity, gross beta activity and a group of gamma emitter radionuclides at three different sampling points in the period between 2008 and 2012. One sampling point was located a few kilometres from the Flix area and the other two were located before and after the DWTP, respectively. From the results obtained, it could be observed that no significant differences were obtained between the samples taken before and after the beginning of the decontamination process began, so it is important to highlight that this project has not affected the quality of the water supplied by the DWTP.

“…Uranium extraction from aqueous phases is typically based on ion-exchange and adsorption by a wide range of adsorbents, such as: ion exchange resins [6], activated carbon [7], zeolite minerals [8], alumina/silica [9], clay minerals [10], talc [11], sometimes in combination with ultra-/nanofiltration [12] and reverse osmosis/electrodialysis [13]. The high environmental cost of uranium contaminated soils in terms of potential toxicity has motivated extensive clean up actions.…”

Uranium contamination of soils and water is a worldwide problem due to geology or anthropogenic release such as mining, or use of inorganic fertilizers. In situ remediation of low and moderately contaminated sites is a complicated procedure due to the complex chemistry of uranium. This study demonstrates that at pH 3.5, a fungal strain isolated from unprocessed uranium bearing shale creates hydrochemical conditions that immobilize 97% of a total of 10 mg L -1 dissolved uranium in a 0.20 μm pore system. The redistribution occurred within 10 minutes and remained for five weeks and just 12% of the inventory was retrieved in the biomass. Size exclusion chromatography of the dissolved phase identified organic substances in the range of more than 60 kD down to 100 D as a response to time of incubation. Geochemical modeling indicates formation of uranium-organic complexes where ligand size, coordination chemistry and their tendency to agglomerate determine the redistribution.
