Nevertheless, water quality and availability are affected by increases in consumption and climate change. Indeed, several areas of Chile are suffering acute water scarcity. Consequently, there is a critical need to develop efficient technologies for wastewater recovery. However, considerations must be given to the fact that some wastewaters have toxic recalcitrant pollutants requiring complex treatments, such as landfill leachate (LL). The general goal of the project is to evaluate the viability of experimentally improving LL quality by conjointly using the solar photo-Fenton process and ultrasound (US), thereby enhancing photocatalysis, ultimately reducing wastewater toxicity. The specific goals are to (i) measure the H2O2 and UV irradiation produced by US in LL (laboratory scale); (ii) evaluate the hydroxyl radicals generated during treatment processes (laboratory scale); (iii) maximize organic-pollutant removal in LL by defining the optimal operating conditions for the photo-Fenton/US process (laboratory scale); (iv) maximize organic-pollutant removal in LL by defining optimal US power/frequency in the sonolytic process (pilot-plant scale); and (v) evaluate toxicity elimination and energy consumption in LL treatments with solar-photocatalytic and US processes (laboratory and pilot-plant scales). The proposed investigation will use a scientific methodology, developing reproducible methods to observe the effects of diverse parameters, all with a focus on maximizing contaminants removal. To characterize LL, several parameters will be evaluated, including chemical oxygen demand, biological oxygen demand, total organic carbon, total dissolved nitrogen, pH, metals, ammonia, colour, biodegradability, toxicity, total suspended solids, conductivity and humic acid. To determine the amount of H2O2 generated by US in a simulated LL, a set of experiments will be run to produce the sonochemical process, applying different US frequencies (100 kHz, 200 kHz and 300 kHz) and powers (100 W, 170 W and 250 W), thus obtaining the kinetic reaction to H2O2 production. The amount of UV irradiation formed due to sonoluminescence will be quantified in the same beaker in the simulated LL. Sonoluminescence intensity during the runs will be measured using a spectro-radiometer. To evaluate the hydroxyl radicals (·OH) generated in the simulated LL during treatment processes, a method based on the oxidation of 2-proponol will be used. To determine the optimal operating conditions for the photo-Fenton/US process to maximize the removal of organic pollutants present in the simulated LL, a set of experiments will be carried out in the same photoreactor (1 L), applying different reagent concentrations, treatment times, and pH levels. To establish optimal US power and frequency in the sonolytic process to maximize the removal of organic pollutants present in a real LL (after its pretreatment), a set of runs will be carried out at pilot-plant scale in a solar photoreactor compound parabolic concentrator (CPC; 12 L useful volume). To evaluate toxicity elimination from the real LL an Aliivibrio fischeri test, respirometer assay, and phytotoxicity assay will be used, followed by determining median effective concentrations (EC50) according to the Probit model. Since a main disadvantage of the proposed treatments is high-energy consumption, specific energy consumption (SEC) and electrical energy per order (EEO) will be determined for all processes. All experiments will be done in triplicate, and filtration and coagulation/flocculation processes as a pretreatment will be used prior to all runs. The expected results of the proposed project are to (i) obtain new knowledge related to joint photo- Fenton and ultrasound wastewater treatments, (ii) demonstrate treatment synergies, and (iii) validate the use of advanced oxidation processes for improving LL. Project results will be reported in papers, through thesis work, and at scientific congresses, strengthening national and international research networks.[/vc_column_text][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649209804184{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5"][vc_row el_class="container mx-auto align-items-center p-md-0 pt-5"][vc_column el_class="p-0"][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649210787516{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5 pb-md-5"][vc_row el_class="container mx-auto align-items-center"][vc_column][/vc_column][/vc_row][/vc_section]
