Six artificial recharge pilot replicates to gain insight into water quality enhancement processes

The processes that control water quality improvement during artificial recharge (filtering, degradation, and adsorption) can be enhanced by adding a reactive barrier containing different types of sorption sites and promoting diverse redox states along the flow path, which increases the range of poll...

While this option looks attractive for renaturazing reclaimed water, three issues have to be analyzed prior to broad scale application: (1) a fair comparison between the system with and without reactive barrier; (2) the role of plants in prevention of clogging and addition of organic carbon; and (3) the removal of pathogens. Here, we describe a pilot installation built to address these issues within a waste water treatment plant that feeds on water reclaimed from the secondary outflow. The installation consists of six systems of recharge basin and aquifer with some variations in the design of the reactive barrier and the heterogeneity of the aquifer. We report preliminary results after one year of operation. We find that (1) the systems are efficient in obtaining a broad range of redox conditions (at least iron and manganese reducing), (2) contaminants of emerging concern are significantly removed (around 80% removal, but very sensitive to the compound), (3) pathogen indicators (E. coli and Enterococci) drop by some 3–5 log units, and (4) the recharge systems maintained infiltration capacity after one year of operation (only the system without plants and the one without reactive barrier displayed some clogging). Overall, the reactive barrier enhances somewhat the performance of the system, but the gain is not dramatic, which suggests that barrier composition needs to be improved.This study was supported by the Water Joint Programming Initiative (JPI)Water Challenges for a ChangingWorld 2014 through the project ACWAPUR (ACcelerated Water PURification during artificial recharge of aquifers: A tool to restore drinking water sources) and partially funded by the Spanish Ministry of Science, Innovation and Universities through PCIN-2015-245. We are very grateful to the staff of ‘Aguas de la Costa Brava' for their assistance, and to Ma Pau Serra-Roig and Ana Julia Acunha for their contribution to the chemical analysis and to Juli_a Garcia for his effort with the field site work.Peer Reviewed20202020-02-0120202020-05-28journal articlehttp://purl.org/coar/resource_type/c_6501VoRhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleapplication/pdfhttps://hdl.handle.net/2117/189346https://dx.doi.org/10.1016/j.chemosphere.2019.124826reponame:UPCommons.
