Dyes and other chemicals laden wastewater is a main environmental concern for increasing the textile industries in many parts of the world. Textile industries consume different kinds of manmade dyes or other chemicals and release huge extents of highly polluted water into the environment. This excessive dye laden wastewater has great impacts on photosynthetic activity in aquatic plants and animals, for example, fish. It may also affect human health due to the presence of components like heavy metals and chlorine in manmade dyes. Thus, wastewater effluent from textile industries must be treated before discharge into the water body. Treatment technologies observed in this review paper include biological treatment methods (fungi, algae, bacteria, and microbial fuel cells), chemical treatment methods (photocatalytic oxidation, ozone, and Fenton’s process), and physicochemical treatment methods (adsorption, ion exchange, coagulation, and filtration). This review also includes the hybrid treatment methods and their cost per m3 of treated wastewater analysis. There are alternative wastewater treatments systems at different steps of effluent generated from the textile operational unit recommend in this review work.

Industry Effluent

Textile industry effluent contains a high amount of toxic colorants. These dyes are carcinogenic and threats to the environment and living beings. In this study, poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-co-HFP) was used as the based polymer for PIMs with bis-(2-ethylhexyl) phosphate (B2EHP) and dioctyl phthalate (DOP) as the carrier and plasticizer. The fabricated PIMs were employed to extract the cation dye (Malachite Green; MG) from the feeding phase. PIMs were also characterized by scanning electron microscopy (SEM), atomic force microscope (AFM), contact angle, water uptake, Fourier-transform infrared spectroscopy (FTIR) and ions exchange capacity. The performance of the PIMs was investigated under various conditions such as percentage of carrier and initial dye concentration. With permeability and flux values of 0.1188 cm/min and 1.1913 mg cm/min, PIM produced with 18% w/w PVDF-co-HFP, 21% w/w B2EHP, 1% w/w DOP and 40% w/w THF and was able to achieve more than 97% of MG extraction. The experimental data were then fitted with a pseudo-second-order (PSO) model, and the calculated R2 value was ~0.99. This shows that the data has a good fit with the PSO model. PIM is a potential alternative technology in textile industry effluent treatment; however, the right formulation is crucial for developing a highly efficient membrane.

Floating Treatment Wetlands

Treatment of textile wastewater prior to its discharge into the environment is a highly concerned issue of the industry. The current established methods in textile industry for effluent treatment are typically high in cost, require range of chemicals along with the generation of concentrated hazardous sludge. It is therefore inevitable to look for economical and eco-friendly ways to treat textile wastewater. Hence, the present study was endeavored to develop green, chemical free and sustainable bacteria inoculated plant based technique for remedying textile bleaching effluents. A lab scale floating treatment wetlands (FTWs) system was developed and implemented for remediation of H2O2 based textile bleaching wastewater. This system was designed by vegetating two free floating aquatic plants Eichhorniacrassipes and Pistia stratiotes. The performance of this system was enhanced by inoculating two pollutant degrading and plant growth promoting bacteria, Bacillus cereus and Bacillus subtilis. The efficacy of this bacterial augmented FTWs system was assessed by monitoring physicochemical parameters of treated wastewater. A substantial decrease in pH, EC, TDS, TSS, BOD and COD was noted. This stamped the effectiveness of this sustainable technique to treat textile effluents.

Background: The extensive industrialization and unrestricted development of dye-utilizing industries coupled with the shortage of proper effluent treatment methods have increased the water pollution. Disposal of dyes in a natural water system is a severe worldwide concern owing to the harmful effects on the ecosystem. Among the available wastewater treatment methods, adsorption is considered as a promising alternative in the elimination of dyes. Methods: There are a variety of ways for the modification of agro-waste, such as (i) acid modification (ii) alkali modification, (iii) surfactant modification, and (iv) preparation of activated carbon, etc. Moreover, numerous techniques have been used for the characterization of modified agro-waste, such as SEM/EDAX, TEM, BET, TGA, and FTIR. Results: From the literature study, it was observed that the adsorption efficiency of various modified agro-waste is reliant on the nature of the adsorbent materials and different batch parameters such as initial dye concentration, solution pH, adsorbent dose, and temperature of the system. In this way, these components must be thought about while evaluating the elimination of dye using various agro-based adsorbents. Conclusion: Modification of agricultural waste usually improved the adsorption capacity of adsorbents due to an escalation in the number of active adsorbing sites, enhancement in the porosity, increase in the surface area, and generation of new functional groups that favor the removal of dye from wastewater. Agro-waste materials being inexpensive, abundant, and renewable can be effectively exploited for the confiscation of dye from aqueous media.

Wet Air Oxidation

The treatment of dyeing and printing wastewater from the textile industry by oxidation was studied. The reaction was carried out in a two-litre high pressure reactor. In order to promote the oxidation of organic pollutants present in the wastewater, experiments were conducted using various catalysts including metal salts, metal oxides, and porous alumina supported metals. All catalysts tested were able to enhance the conversion of organic compounds in wastewater, shorten the reaction time, and lower the reaction temperature. The alumina supported catalyst has an advantage over other catalysts in that it can be easily separated from the treated wastewater by filtration and recycled. The conditions in preparing the catalyst supported by porous alumina were experimentally optimised.
