“…An industrial BOD/TOC ratio of 0.75 is consistent with ratios reported in literature for pulp and wood production (Grötzner et al, 2018), which is the majority of E -PRTR emissions to freshwaters. It may largely underestimate waste from aquaculture or other agro-industries, for which emission BOD/TOC ratio has been reported to be larger than two (Quayle et al, 2009; Kwarciak-Kozłowska and Bień, 2018), however agro-industries in the E-PRTR accounted for about 5% of TOC emissions, whereas aquaculture emissions are directly discharged to the sea and unmonitored therefore could not influence calibration.…”

“…Annual facility releases to water (net to transfers) of Total Organic Carbon (TOC) for the seven-year period 2010–2016 were averaged to obtain mean annual facility TOC emissions (t/y). The ratio BOD/TOC in industrial effluents depends on the type of industrial waste and treatment applied, and may range from as low as 0.1–0.6 in petrochemical effluents, to 0.5–0.75 in pulp and paper mill facilities, to >2 for agro-industries (Dubber and Gray, 2010; Mook et al, 2012; Quayle et al, 2009; Banerjee and Ghoshal, 2017; Christian et al, 2017; Bustillo-Lecompte et al, 2018; Grötzner et al, 2018; Kwarciak-Kozłowska and Bień, 2018). Thus, the BOD/TOC ratio was introduced as a model calibration parameter to assess BOD sources from industries (BOD = TOC*bod/toc; Table 1).…”

Biochemical Oxygen Demand (BOD) is an indicator of organic pollution in freshwater bodies correlated to microbiological contamination. High BOD concentrations reduce oxygen availability, degrade aquatic habitats and biodiversity, and impair water use. High BOD loadings to freshwater systems are mainly coming from anthropogenic sources, comprising domestic and livestock waste, industrial emissions, and combined sewer overflows. We developed a conceptual model (GREEN + BOD ) to assess mean annual current organic pollution (BOD fluxes) across Europe. The model was informed with the latest available European datasets of domestic and industrial emissions, population and livestock densities. Model parameters were calibrated using 2008–2012 mean annual BOD concentrations measured in 2157 European monitoring stations, and validated with other 1134 stations. The most sensitive model parameters were abatement of BOD by secondary treatment and the BOD decay exponent of travel time. The mean BOD concentrations measured in monitored stations was 2.10 mg O 2 /L and predicted concentrations were 2.54 mg O 2 /L; the 90th percentile of monitored BOD concentration was 3.51 mg O 2 /L while the predicted one was 4.76 mg O 2 /L. The model could correctly classify reaches for BOD concentrations classes, from high to poor quality, in 69% of cases. High overestimations (incorrect classification by 2 or more classes) were 2% and large underestimations were 5% of cases. Across Europe about 12% of freshwater network was estimated to be failing good quality due to excessive BOD concentrations (>5 mg O 2 /L). Dominant sources of BOD to freshwaters and seas were point sources and emissions from intensive livestock systems. Comparison with previous assessments confirms a decline of BOD pollution since the introduction of EU legislation regulating water pollution.

“…Conventional P&P treatment processes (biological and physiochemical methods), including activated sludge processes, aerated lagoons, and biological reactors, have limited application in the case of refractory organic pollutants. Therefore, these biologically treated e uents still contain many complex structural compounds, such as lignin and its derivatives (Elnakar and Buchanan 2019;Grotzner et al 2018;Toczylowska-Maminska 2017). To satisfy harsher environmental regulations and to avoid secondary wastewater pollution, it is necessary to search for environmentally friendly and e cient techniques for P&P industry wastewater treatment (Marques et al 2017;Sridhar et al 2011).…”

This study focused on the feasibility of using Fe 3 O 4 /graphene oxide (FGO) nanocomposites as heterogeneous catalysts for the advanced treatment of real industrial wastewater. FGO nanocomposites with different graphene oxide (GO) ratios were synthesized by co-precipitating iron salts onto GO sheets in basic solution. Characterization of the resulting material structures and functionalities was performed using a range of analytical techniques. A low GO loading afforded a good Fe 3 O 4 nanoparticle dispersibility and resulted in a higher Brunauer-Emmett-Teller surface area and pore volume. The FGO nanocomposites and pure Fe 3 O 4 were used to treat papermaking wastewater in a heterogeneous photo-Fenton process. The results suggested that the nanocomposite designated FGO1 (GO loading of 25 mg) exhibits a higher photocatalytic e ciency than other FGO nanocomposites and pure Fe 3 O 4 . A maximum chemical oxygen demand degradation e ciency of 89.6% was achieved in 80 min with 1.5 g.L − 1 FGO1 at pH 3. The degradation of different pollutants present in wastewater was evaluated with the aid of gas chromatography-mass spectrometry and 3D excitation-emission-matrix analysis. Inductively coupled plasma atomic emission spectroscopy and magnetic measurements con rmed that the FGO1 nanocomposites possess a low iron leachability and a high reusability. Thus, a comprehensive advanced treatment of real industrial wastewater using a magnetic FGO catalyst is demonstrated.

“…A scheme of treatments coagulation-flocculation-sedimentation (CFS) and Fenton has been used to treat the paper and pulp waste water. By using these coagulation-flocculation-sedimentation (CFS) and Fenton processes sequentially 61% of COD removal was obtained at an alum dosage of 750 mg/l, pH 3 and settling time of 60 min, Grötzner and Melchiors (2018).…”

Abatement of water pollution is being a major concern to be dealt with, as the scarcity of water for basic needs of human beings is increasing drastically. As a part of diminishing water pollution, treatment of industrial wastewater prior to disposal plays a paramount role. Due to the typical characteristics of pesticide, intermediate industrial waste water the treatment is also challenging issue. In this study three different sequential methodologies (Methodology-I: combined rotavapour distillation, fenton and anaerobic biological process, Methodology-II: combined rotavapour distillation, photo fenton and anaerobic biological process, Methodology-III combined coagulation, fenton, electro oxidation and anaerobic biological process) has been evaluated for the treatment of pesticide intermediate industrial wastewater. Among the three sequential methodologies opted in this study for the treatment of pesticide intermediate industrial wastewater, percentage removal of COD was 95% in methodology-1 (i.e. combined rotavapor distillation, fenton and anaerobic biological treatment).
