“…The color in the stillage, in addition to being attributed to the content of melanoidins, is due to the presence of phenolic compounds (España-Gamboa et al 2017). Phenol is a recalcitrant compound (Othman et al 2008) and the melanoidins are considered the most recalcitrant dye (Johnson et al 2019). Likewise, phenolic and polyphenolic compounds in vinasses can inhibit microorganisms (Freitas et al 2018;Ao et al 2020).…”

“…Most colloids in aqueous solution have a negative charge, producing a colloidal stable solution (Derjaguin 1989). This stability is reduced thanks to charge neutralization, and ionic layer compression, which reduces the repulsive forces between colloidal particles (Johnson et al 2019). Phenolic compounds and high molecular weight nitrogen compounds like melanoidins are related to color (España-Gamboa et al 2017).…”

“…The phenolic compounds and melanoidins present in the vinasses possess antimicrobial activity, and they are toxic (Borja et al 1993;Rufián-Henares and Morales 2007;Bouarab-Chibane et al 2019). Johnson et al (2019) reported that conventional biological processes are not efficient for the removal of melanoidins because they can only remove up to 7%. Morever, due to their microbial inhibiting activity, the color associated with these two compounds must be removed before using a biological process.…”

Agro-industrial waste is generated in large quantities, producing negative environmental impacts. For instance, in the distillation process of vinasses, up to 15 L are produced per alcohol produced. Therefore, it is necessary to search for ecological alternatives. Biological treatments are not recommended because vinasses contain compounds, such as melanoidins, which exert inhibitory activity against microorganisms. Thanks to this activity, melanoidins could be removed, recovered, and become a value-added product. In this study, Opuntia ficus-indica (OFI) mucilage, a natural biopolymer as coadjuvant, was used to improve the coagulation-flocculation process in the treatment of real samples of mezcal vinasses, after evaluating the individual effect of aluminum sulfate and ferric chloride. It was possible to eliminate 90% of color using ferric chloride, showing better removals than aluminum sulfate. However, the effect of ferric chloride plus OFI mucilage generated an adverse effect because the removal was under 17%. The individual effect of ferric chloride for chemical oxygen demand (COD) removal was 28%. This removal was improved by the addition of OFI mucilage, as it was able to increase removal to 84%. The natural coadjuvant was shown to be effective in the COD removal in the treatment of mezcal vinasse using the coagulation-flocculation process.

“…Coagulants are with opposite charge to that of the particles present in the wastewater hence counteract with the charges. The four steps describing the mechanism of C-F as discussed by Johnson, Ali, and Kumar, (2019) are (i) interparticle bridging, (ii) charge neutralization, (iii) ionic layer compression and (iv) sweep coagulation, reducing the repulsive forces between colloidal particles.…”

The present study compares the treatment of pharmaceutical industry wastewater (PIWW) by coagulation‐flocculation (C‐F) and electrocoagulation (EC) techniques using response surface methodology (RSM). EC was performed with waste food‐grade Aluminium (Al) foil as a sacrificial anode. In C‐F, to minimize chemical usage, dual coagulants Aloe vera (organic) and ferric chloride (chemical) were used. Optimization using RSM for C‐F showed chemical oxygen demand (COD) reduction of 60.25 ± 0.28% at optimum operating conditions with R2 = 0.964 and adj‐R2 = 0.928, whereas EC resulted in COD reduction of 78.23 ± 0.38% and energy consumption 1.498 ± 0.0076kWh/m3 with R2 = 0.978 and adj‐R2 = 0.956. The result showed that the use of food‐grade waste Al foil as anode electrode (in EC) and the use of dual coagulant (in C‐F) can reduce COD from industrial effluent efficiently contributing to less hazardous sludge generation.

“…However, typical biological methods (e.g., activated sludge process) cannot eradicate these organic pollutants rapidly due to their large size, complex molecular structure, and chemical nature that converts them as non-biodegradable in the environment (Kim et al 2004). Advanced oxidation processes (AOPs) are also used to destroy wastewater dyes effectively, but their operation and maintenance costs are too high (Al-Mamun et al 2019; Johnson et al 2019). In this case, the application of gamma radiation, also known as ionizing radiation, can be used as a remedy for textile wastewater treatment as this is more powerful, economical, and environmentally favorable.…”

This investigation concentrates on the possibility of using gamma radiation for the decomposition of textile wastewater and reuse as irrigation water. The real wastewater sample was irradiated at four different radiation doses of 3, 5, 8, and 10 kGy. After irradiation at 8–10 KGy, physicochemical parameters, i.e., pH, turbidity, EC, total suspended solids (TSS), total dissolved solids (TDS), biological oxygen demand (BOD5), and chemical oxygen demand (COD) have decreased sharply and approached to the expected value. At maximum 10 KGy radiation dose, 59.0 % BOD5 and 71.6 % COD removal have been achieved, accelerating the enhancement in biodegradability index (BOD5/COD, 0.43). Ammonium and total nitrogen have improved up to 87.0 % and 94.5 % after irradiation at 10 KGy doses. These treated textile wastewater samples were reused to grow Capsicum frutescens plants to inspect the fertility responses. When Capsicum plants were nourished by textile wastewater irradiated at 8–10 kGy, the dry masses of the fruits, moisture content, root length, average plant height, average number of leaves, and total number of fruits were increased in comparison to those plants nourished by simply water and raw wastewater. The elemental analysis confirmed that the heavy metals concentration in Capsicum fruits decreased gradually with higher radiation doses. Helpful macro and micronutrients for plant production such as Na, K, and Mg were raised at a sufficient level of 47.7 %, 23.5 %, and 63.8 % for 10 KGy, whereas the highest 50.0 % increase in Ca concentration was found for 8 KGy fruit samples.
