“…The availability of water resources suitable for human use has become increasingly scarce due to (Filipić et al, 2022) a combination of several factors, such as increased water demand for industrial (e.g., textiles, drugs, and plastics production) (Bethi et al, 2021) and agricultural activities (Soto-Verjel et al, 2022) leading to the emission of several classes of chemicals in the environment (e.g., petrochemicals, pharmaceuticals, plant protection products, and fertilizers) (Bokhari et al, 2021;Matheus et al, 2020;Soto-Verjel et al, 2022;Thanekar et al, 2021;Yu et al, 2021). This issue is also further complicated by the predicted increase in urban population, which is estimated to reach up to 6.7 billion by 2050, with the consequent increase in both wastewater produced and freshwater water resources needed (He et al, 2021;United Nations/DESA, 2019).…”

“…Previous studies have shown that the chemical oxygen demand (COD) and biological oxygen demand (BOD) of pesticide production wastewaters are within the range of 150-33750 mg/L and 30-11590 mg/L, respectively (Lindsey Goodwin et al 2018). Matheus et al (2020) reported values of total ammoniacal nitrogen, total and soluble COD of 150 mg/L, 16900 mg/L and 12300 mg/L, respectively, for a wastewater from a pesticide formulation industry resulting from various washing operations. The concentration of pesticide substances varies substantially, with some ingredients being detected at concentrations of up to 2500 mg/L (Lindsey Goodwin et al 2018).…”

Proper treatment and reuse of industrial wastewaters are e cient ways to mitigate their environmental impacts. In this work, a pesticide formulation wastewater pretreated by activated carbon was combined with sewage (4:96) and subjected to biotreatment in a lab-scale moving-bed bio lm reactor (MBBR) with 50% media lling ratio and 6h HRT. Throughout 180 days, e cient removal was achieved for organic matter (86%, tCOD) and ammonium (88%). Additionally, the MBBR e uent exhibited higher quality than the water of the river used by the pesticide industry. For evaluating the possibility of wastewater reuse, the e uents from the MBBR (M) and a lubricant industry (L, from the same industrial site) were combined with the river water (R) that feeds the industrial water treatment plant (WTP) and submitted to a lab-scale reproduced WTP: coagulation/ occulation, sedimentation, sand ltration and micro ltration. River water and two combinations (RM: 85:15 and RML: 80:15:5) were assessed. The mixtures improved the e ciency of the lab-reproduced WTP; however, the fouling potential was high (SDI 15 >5) for reverse osmosis at the end of the WTP. Thus, after micro ltration, two ultra ltration (UF) membranes (10 and 50 kDa) were tested, producing similar quality water (0.02 NTU, low SDI and color). After UF, the total turbidity and color removals for R, RM and RML were, respectively, 99.87%, 99.84% and 99.81%, and 96.2%, 87.3% and 93.1%. The UF implementation produced stable high-quality water, implying a reduction of RO membrane costs and cleaning frequency, while increasing the permeate ux. Ultimately, complete wastewater reuse was enabled by the proposed chain.

“…Aquatic contamination with recalcitrant organic compounds released by industrial, agricultural, and transportation activities represent a serious threat to human health and life quality. Pesticide compounds including herbicides, insecticides, and fungicides have large contamination potential due to their continuous use in agricultural area and long term persistency in the ecological system [ 1 , 2 , 3 ]. The agricultural accumulation of organic compounds, such as S-metolachlor, cyprodinil, iprodione, tebuconazole, etc., in sediment and biota, are sources of serious environmental pollution [ 4 , 5 ].…”

A dual S-scheme Cu2S_TiO2_WO3 heterostructure was constructed by sol–gel method using a two-step procedure. Due to the synthesis parameters and annealing treatment the heterostructure is characterized by sulfur deficit and oxygen excess allowing the passivation of oxygen vacancies. The photocatalytic activity was evaluated under UV and UV–Vis irradiation scenarios using S-MCh as reference pollutant. The heterostructure is composed on orthorhombic Cu2S, anatase TiO2 and monoclinic WO3 with crystallite sizes varying from 65.2 Å for Cu2S to 97.1 Å for WO3. The heterostructure exhibit a dense morphology with pellets and particle-like morphology closely combined in a relatively compact assembly. The surface elemental composition indicate that the heterostructure maintain a similar atomic ratio as established during the synthesis with a slight sulfur deficit due to the annealing treatments. The results indicate that the three-component heterostructure have higher photocatalytic efficiency (61%) comparing with two-component heterostructure or bare components. Moreover, Cu2S_TiO2_WO3 exhibit a superior constant rate (0.114 s−1) due to the high concentration of photogenerated charge carriers, efficient charge separation and migration.
