“…The comparison of the results of phytotoxicity assay with other toxicity test, such as zootoxicity for the same treated wastewater showed differences. For example, Oliveira et al (2020) showed no reduction of the phytotoxicity, while for zootoxicity a maximum reduction of 47% was obtained. The same was observed for the study of Przystaś et al (2018), but with opposite results.…”

For other toxicity tests, as genotoxicity and zootoxicity, there are fewer studies available in literature (Paździor et al, 2017;Dhaouefi et al, 2018;Przystaś et al, 2018;Oliveira et al, 2020).

Current Trends on Role of Biological Treatment in Integrated Treatment Technologies of Textile Wastewater

Wastewater discharge is a matter of concern as it is the primary source of water pollution. Consequently, wastewater treatment plays a key role in reducing the negative impact that wastewater discharge produce into the environment. Particularly, the effluents produced by textile industry are composed of high concentration of hazardous compounds such as dyes, as well as having high levels of chemical and biological oxygen demand, suspended solids, variable pH, and high concentration of salt. Main efforts have been focused on the development of methods consuming less water or reusing it, and also on the development of dyes with a better fixation capacity. However, the problem of how to treat these harmful effluents is still pending. Different treatment technologies have been developed, such as coagulation-flocculation, adsorption, membrane filtration, reverse osmosis, advanced oxidation, and biological processes (activated sludge, anaerobic-aerobic treatment, and membrane bioreactor). Concerning to biological treatments, even though they are considered as the most environmentally friendly and economic methods, their industrial application is still uncertain. On the one hand, this is due to the costs of treatment plants installation and, on the other, to the fact that most of the studies are carried out with simulated or diluted effluents that do not represent what really happens in the industries. Integrated treatment technologies by combining the efficiency two or more methodologies used to be more efficient for the decontamination of textile wastewater, than treatments used separately. The elimination of hazardous compounds had been reported using combination of physical, chemical, and biological processes. On this way, as degradation products can sometimes be even more toxic than the parent compounds, effluent toxicity assessment is an essential feature in the development of these alternatives. This article provides a critical view on the state of art of biological treatment, the degree of advancement and the prospects for their application, also discussing the concept of integrated treatment and the importance of including toxicity assays to reach an integral approach to wastewater treatment.

“…In recent years, a wide range of wastewater treatment methodologies has been investigated [4][5][6] to eliminate organic dyes out of which advanced oxidation processes (AOPs) cast a lot of attention due to their prominent advantages. AOPs, based on the production of highly active oxygen species (namely OH 2 ) throughout a chain of chemical reactions, are used to total mineralization of a wide range of persistent organic pollutants.…”

This study aimed to propose a mathematical method to investigate and optimize the simultaneous elimination process of multiple organic pollutants using the Fenton process. Hence, the treatment of rhodamine B (RB) and acid red 14 (AR14) dyes in their binary solution was studied. Multivariate curve resolution alternating least square (MCR-ALS), a novel chemometric method, was applied along with correlation constraints to resolute the UV-Vis spectrophotometric data, enabling quantification of investigated dyes despite a high spectral overlapping. Response surface methodology was adopted to assess the model and optimize individual and interactive effects of three independent factors (Fe 2+ , H 2 O 2 and initial pH) on the simultaneous elimination of RB and AR14. The values of the regression coefficient for RB and AR14 were determined as 98.48 and 98.67 percent, respectively, revealing the reliability of the obtained polynomial models to predict decolorization efficiencies. Desirability function was employed to optimize the independent variables to attain the highest possible degradation performance for both dyes in their binary solution. At the optimum point of operation ([Fe 2+ ] = 143.88 mg/L, [H 2 O 2 ] = 126.89 mg/L and pH = 3.71), degradation efficiencies of RB and AR14 were found as 81.58% and 80.22%, respectively, which were nearly identical to the experimental results.

“…waste water with large amounts of azo dyes, like methyl orange (MO), of which the metabolites are often carcinogenic, teratogenic, mutagenic and biotoxic for living organisms (Jia et al 2019). Recently, large numbers of researches on the removal of water polutants have been made, including biodegradation (Oliveira et al 2020), physical adsorption (Ali et al 2018;Ali et al 2019;Naushad et al 2019a;, catalytic oxidation or reduction degradation (Ahsan et al 2019a(Ahsan et al , 2019b(Ahsan et al , 2019c(Ahsan et al , 2020a. Among them, advanced oxidation processes (AOPs), including UV/vis photolysis oxidation, catalytic wet air oxidation, ozone oxidation, electrochemical oxidation and Fenton oxidation, are commonly considered as promising approaches to remove refractory and toxic organic dyes (Chan et al 2011;Tijani et al 2014;Deng & Zhao 2015;Cheng et al 2016;Ahsan et al 2021).…”

Fe3O4-NPs/orange-peel (MOP) composite was prepared via one-step in-situ co-precipitation method as magnetic heterogeneous Fenton-like catalyst. The properties of MOP were characterized by SEM, TEM, BET, XRD, FT-IR, TGA and XPS technologies. Its Fenton-like catalytic responses towards removal of methyl orange (MO) were investigated, in which the effects of initial dye concentration, pH, temperature and H2O2 dosage were studied. The MO degradation ratio up to 98.0% was obtained within 20 min in optimized conditions. The catalyst also shows excellent catalytic stability exhibiting nearly 90% degradation ratio in 10th cycle within 20 min, whereas pure Fe3O4-NPs showing only 62.5% in this stage. Due to the stabilization of complexing orange peel hydroxyl to Fe oxide in the composite and its magnetic separation property, Fe3O4-NPs/orange-peel composite exhibits excellent Fenton-like catalytic performance which offers great prospects for low-cost and high-efficiency organic dye wastewater treatment.
