“…The separate use of biological treatment methods as SBR and oxidation method cannot help textile wastewater to meet discharge standards; however, the integration of Fenton's oxidation process with a downstream SBR provides much better removal of organic matter (88-98 % for COD, 83-95 % for BOD 5 , and 91-98 % for DOC-values depending on the particular textile effluent being used) and color (>99 %) [26]. Punzi and colleagues have suggested that the use of ozonation as short posttreatment after a biological process can be beneficial for the degradation of recalcitrant compounds and removal of toxicity of the textile wastewater [27].…”

Background: The sedge mats (dyeing, weaving processes, and small-scale livestock farm at the same place) craft villages in the Mekong Delta (Vietnam) are the most popular craft villages in Vietnam, especially in the Mekong Delta area. These craft villages generate typical emissions such as exhaust gas from burning fuel, wastewater from the sedge mats dyeing and weaving process, wastewater from livestock farm, and solid waste. Methods: In this study, an ecological system, so-called VICRAIZES (Vietnam Craft villages Agro-based Industrial Zero Emission System), has been developed with the purpose to decrease pollution and enhance resource efficiency at those craft villages. The proposed ecosystem focused on measures such as (1) biogas tank (using residue pieces of solid sedge mats from weaving processing) supplied gas for burning the dyeing tank, (2) wastewater treatment system combining three components: innovative septic tank having upward flow thin baffles, anaerobic filter compartment, and bio-pond, and (3) composting area. The system was applied for a number of household craft villages in Dong Thap Province, Vietnam. Results: The results of system demonstration show significant emission decreases: 93 % greenhouse gas (CO 2 and CH 4 ), 97 % BOD 5 in wastewater, around 30 kg/day biodegradable garbage are composted and used as organic fertilizers at the household needs (which increase family income of around 115 million VND/year), low initial investment and operating cost, simple operating procedure, etc., which are favorable and applicable at the low income sedge mats dyeing and weaving craft villages in the Mekong Delta area, Vietnam, and probably at other developing countries. Conclusions: The VICRAIZES system implementation shows remarkable benefits/advantages on environmental, economic, and technical aspects giving real chances for more comprehensive application at similar craft villages in Vietnam and possibly in other developing countries.

“…Importantly, the accumulation of dyes in water can seriously damage food chains of humans and animals (Rodrigues da Silva et al 2012). Most of these dyes are toxic, mutagenic, or carcinogenic (Punzi et al 2015). Methylene blue (MB) is a cationic dye having various applications in chemistry, biology, medical science, and dyeing industries.…”

In this study, the adsorption potential of activated carbon prepared from Ziziphus mauritiana nuts for the removal of methylene blue (MB) from aqueous solution has been investigated using batch mode experiments. The effects of some operating parameters on the removal dye such as, initial pH (2-12), temperature (298-328 K), initial MB concentration (20-100 mg L -1 ), and contact time (5-70 min) were investigated. Adsorption kinetic showed that the rate adsorption followed the pseudo-second-order kinetic model. Four adsorption isotherms models were applied to experimental equilibrium data (Langmuir, Freundlich, Redlich-Peterson, and Fritz-Schlunder) and the different constants were calculated using non-linear equations models. Fritz-Schlunder model was found the best one to describe the adsorption process which suggests that the adsorption of MB onto activated carbon derived from Ziziphus mauritiana is heterogeneous with a multilayer. Thermodynamic adsorption showed that the process was endothermic and spontaneous in nature.

“…Many of the azo dyes are toxic to aquatic environment and human heath (Brillas and Martinez-Huitle 2015), carcinogenic (de Lima et al 2007), mutagenic (Chequer et al 2011), genotoxic (Chequer et al 2009), cytotoxic (Ferraz et al 2011), estrogenic, and anti-estrogenic (Bazin et al 2012). Besides, their biotransformation products, such as aromatic amines and derivatives, are usually more toxic than the untreated target compound (Byberg et al 2013;Punzi et al 2015b).…”

The role of different operational parameters related to Fenton reactions (pH, concentration of Fe and HO, and reaction time) and of Cl and SO was investigated in the degradation of the azo dye Direct Red 81, expressed in terms of its decolorization. The factorial design and Pareto's charts showed that only Fe concentration and pH influence the decolorization under the conditions evaluated. So, only these parameters were optimized using the response surface model. Under the best experimental conditions (initial pH 2.5, 11 mg L Fe, 78 mg L HO, and 20 min of reaction), 94 % of decolorization was achieved. However, even under the these conditions, but in the presence of Cl and SO , a striking loss of efficiency was observed as the concentration of these ions was increased, due the formation of chloride- and sulfate-iron complexes and less reactive inorganic radicals (Cl and SO). The results show that the presence of Cl is more deleterious, since sulfate-iron complexes are more reactive towards HO, and the SO turns out to favor the degradation. On the other hand, the negative effect of Cl can be compensated by increasing the chloride concentration up to 300 mmol L. In addition, although a high degradation level has been obtained by monitoring the dye absorbance and by HPLC-UV, a low mineralization occurred, being generated degradation products of higher ecotoxicity to Vibrio fischeri, showing the need of subsequent studies to identify these compounds as well as the application of additional treatments aiming the complete mineralization of the dye.
