“…Thus, these physicochemical parameters can be correlated with pollutant removal efficiency and nutrient uptake. Ortiz‐Marin et al (2020) evaluated a UV/H 2 O 2 system to treat a pharmaceutical effluent with about 500 mg/L total Kjeldahl nitrogen. Chemical transformation of nitrogen was intrinsically associated with low pH levels and high pOR.…”

“…Municipal wastewater comprises mainly C, N, and P, in proportions, known as “C:N:P ratios,” of 100:14:1. Crop wastewater and LSWW stand out for their high content of P and N in relation to C, with C:N:P ratios around 20:4:1 for CropWW (Bardi et al 2017; Ortiz‐Marin et al 2020) and 100:35:1 for LSWW (Bardi et al 2017; Mendivil‐García et al 2020), derived from the content of organophosphate pesticides and physiological residues containing veterinary drugs (Kullik and Belknap 2017).…”

“…In this regard, the lowest concentrations of TOC and malathion to be treated in the biological systems were considered in order to reduce the organic load to the CWs which have better performance at low organic loads [5,39]. Although ORP values did not show a clear trend linked to irradiation time, higher ORP values were observed for the 65 mM of H 2 O 2 , which is mainly because H 2 O 2 determines oxidative conditions of the treatment regardless organic matter degradation and/or oxidation of dissolved solids [38,39]. Indeed, efficiencies of malathion and TOC removal with 65 mM were higher than with 82 mM H 2 O 2 , despite no statistical difference (p = 0.11).…”

Intensive agriculture has led to the increasing application of pesticides, such as malathion, thus generating large volumes of untreated cropland wastewater (CropWW). In this work, a hybrid system constructed wetlands (CW) coupled in continuous with an optimized UV/H2O2 pretreatment was evaluated for the efficient removal of malathion contained in CropWW. In the first stage, 90 min UV irradiation time (UV IR) and 65 mM hydrogen peroxide (H2O2) were identified as optimal operation parameters through a central composite design. The second stage consisted of CW planted with Phragmites australis collected from the agricultural discharge area and operated as a piston flow reactor. Furthermore, CW hydraulic residence times (HRT) of 1, 2 and 3 days, including hydraulic coupling, were evaluated. The removal efficiencies obtained in the first stage (UV/H2O2) were 94 ± 2.5% of malathion and 45 ± 2.5% of total organic carbon (TOC). In stage two (CW) 65 ± 9.6% TOC removal was achieved during the first 17 days, from which around 24% was associated to the biosorption of malathion byproducts. Subsequently, and until the operation ends, CW removed about 80% of TOC for 2 and 3 days HRT, with no significant differences (p > 0.2), which is higher than those reported in several studies involving only advanced oxidation processes (AOP) with UV IR times above 240 min and even for systems using catalysts. The results obtained indicate that the system UV/H2O2-CW is a technically suitable option for the treatment of CropWW with a high content of malathion mainly found in developing countries. Moreover, the hybrid system proposed also represent significant reduction in the size of the treatment plant.
