All over the world, the treatment of textile wastewater has become a significant problem due to the development of the textile industry. Particularly, the treatment of synthetic dyes, which are found abundantly amounts in textile wastewater, has gained importance. Recent studies have focused on the use of biological treatment technologies to remove pollutants in water. On the other hand, the disposal of wastes from biological treatment technologies was considered as another environmental problem. This study aims to compare the antimicrobial properties of the extract obtained from dye loaded and un-loaded lichen biomass after the biosorption process. According to the results of this study, it was found that the extract obtained from the waste lichen biomass, which has loaded with the textile dye in the decolorization process, showed a similar antimicrobial effect with the unloaded lichen extract. To sum up the waste lichen biomass used to remove textile dyes can be reused for the application of antimicrobial products.

Abstract The textile industry in India plays a vital role in the economic growth of the nation. The growth of the textile industry not only impacts the economy of a country but also influences the global economy and mutual exchange of technology between the countries. However, the textile industry also generates an enormous quantity of waste as waste sludge, fibers and chemically polluted waters. The chemically polluted textile wastewater degrades the quality of the soil and water when it mixes with these natural resources and its dependent habitats and environment. Owing to the existing problem of solid and liquid waste, textile industries are facing major problems in environment pollution. Therefore, researchers and the textile industries are focusing on the reduction of textile wastewater and the formulation of alternative efficient treatment techniques without hampering the environment. Hence, the present literature survey mainly concentrates on the various wastewater treatment techniques and their advantages. Moreover, the focus of the study was to describe the methods for the reduction of environmental waste and effective utilization of recycled water with zero wastewater management techniques. The alternative methods for the reduction of textile waste are also covered in this investigation. Finally, this paper also suggests utilization of solid wastes after treatment of wastewater in other sectors like construction for the preparation of low-grade tiles and or bricks by replacing the cement normally used in their manufacturing.

Introduction: Textile industry effluent is a complex sewage with chemical and color materials that is discharged into the environment and can cause serious problems. In this way using advanced oxidation methods and finding the best methods for removing color materials is necessary. An experimental method was done on Kashan textile industry effluent in laboratory scale and batch system. Material and Methods: Initially, optimal condition was obtained for O3 and H2O2 and followed by advanced oxidation methods (UV/O3, UV/H2O2, O3/H2O2 and UV/H2O2/O3) in different reaction times and pH on dye removal and COD (chemical oxygen demand) were determined. The results were compared with complex repetition method. Results: The results of this research showed that dye removal impact and COD based on the type of process and reaction time in UV/H2O2/O3 by 30 minute time duration, was the most effective method. UV/H2O2 in 10 minute time duration was the least effective method. COD and color removal, based on the process in UV/H2O2/O3 and pH = 6 was the most effective. The effect of UV/H2O2 and pH = 4 was the least efficient method on dye material removing. Results showed that the treatment time was effective on color removing (P < 0/001) statistically. Conclusion: It can be concluded that UV/H2O2/O3 was the most efficient on color removing process, compared to the others, due to co-incidence presence of strongly numerous oxidants and their aggravating effect through producing active hydroxyl radicals (OH˚).

Adsorption is one of the promising strategies for aqueous dye remediation. A lot of attention has been paid to textile wastewater treatment using smart materials. In this study, we formed the N-FeO to test its properties by using FTIR and TEM technique. We also tested AC, N-FeO and mixed N-FeO/AC to investigate the adsorption efficiency of lipophilic cationic dye (LCD) removal from aqueous solutions of each individually under. The results showed that the removal percentage of lipophilic cationic dye by using activated crbon was increasing significantly with AC wight (Pvalue < 0.01), and the highst removal was to 0.1 ppm of dye (52%). While the lowest dye removal percentage was 14.3% of 1ppm dye concentration and 0.05g AC. The rmoval of dye, by using N-FeO, was depant on the concentration of dye and the amount of N-FeO. The highst percentage of dye removal was 45% ±3.69 of 0.1 ppm concentration with using 0.3g and 0.35 g of N-FeO. While the lowest removal percentage of dye was 7.3%±2.49 of 1ppm with using 0.05g of N-FeO. The using of N-FeO/AC mixture leads to a significant removal percentage of dye in different concentrations compared with using each of them a lone. By this mixture, the highest removal of dye reached to 98%±3.47, 92%±3.96, and 88%±1.44 of 0.1ppm, 0.5ppm, and 1ppm respectively by using 0.35g of N-FeO/AC mixture. While the lowest dye removal percentage was 54%±1.1, 46%±0.98, and 40%±2.49 of 0.1ppm, 0.5ppm, and 1ppm respectively by using 0.05g of N-FeO/AC mixture. This study suggested that the increase in adsorption at low dye concentration was due to the availability of active sites that were saturated While the adsorbing surface area will increase with the N-FeO/AC mixture, the percentage of dye removal at constant temperature will also increase, and it is nessesary to using more chemometric test of this mixture for testing the best removal environment of this kind of dye.

The current work was devoted to study the operating feasibility using membranes which were manufactured locally, two membrance types were tested nanofiltration (NF) and ultrafiltration (UF) membrane to treat the effluent of Al-kut textile industry. Based on the usage rate in Iraq textile industries, terasil navy blue (TNB) is one of the common disperse dyes discharged in effluent wastewater. Therefore this type of dyes was selected to experience in this study. Parameters such as effects of TNB concentration, feed temperature and operating pressure and its effect on permeate flux noticed and the TNB rejection were investigated. The results show that when using NF system at pressure of 10 bar and when the temperature increased from 25ºC to 37ºC, it was found that an increase in permeate flux from 46.97 to 50 LMH.  However, in UF system permeate flux was increased from 41.32 to 45.04 LMH.  While dye removal was decline in NF membrane from 96.00 to 95.14 and for UF from 79.50 to 78.67 when the temperature raised from 25ºC to 37ºC.The pressure state positive effects on dye removal for both membranes, it show that NF membrane is better in treatment than UF membrane.

The textile industry provides for the needs of people especially in apparel and household items. The industry also discharges dye-containing wastewater that is typically challenging to treat. Despite the application of the biological and chemical treatments for the treatment of textile wastewater, these methods have their own drawbacks such as non-environment friendly, high cost and energy intensive. This research investigates the efficiency of the celestine blue dye removal from simulated textile wastewater by electrocoagulation (EC) method using iron (Fe) electrodes through an electrolytic cell, integrated with nylon 6,6 nanofiber (NF) membrane filtration for the separation of the flocculants from aqueous water. Based on the results, the integrated system achieves a high dye removal efficiency of 79.4%, by using 1000 ppm of sodium chloride as the electrolyte and 2 V of voltage at a constant pH of 7 and 10 ppm celestine blue dye solution, compared to the standalone EC method in which only 43.2% removal was achieved. Atomic absorption spectroscopy analysis was used to identify the traces of iron in the residual EC solution confirming the absence of iron. The EC-integrated membrane system thus shows superior performance compared to the conventional method whereby an additional 10–30% of dye was removed at 1 V and 2 V using similar energy consumptions.

Abstract Currently, textile wastewater management focuses on dye removal efficiency and operating costs. Dual responsive polymers are choice materials because they can extract diverse organic compounds from water at their phase transition point. They are copolymers of the acrylamide class, and have been fully characterized by FT-IR, 1H-NMR, DSC, GPC and surface area analysis. Of the five dual responsive polymers, the copolymer of NIPAAM and DMAEMA (CoP-1) offers the best extraction of acidic and basic dyes from wastewater. All copolymers investigated can achieve better than 90% dye removal when used at 4 mg/ml concentration. This dye-scavenging efficiency increases to almost 99% at 3 mg/ml, on conversion of the copolymers to nanofibers in 300 to 500 nm size. Langmuir and Freundlich isotherms were constructed to study the mechanism of dye adsorption. The nanofibers have been shown to be reusable for removal of dyes from water, suggesting that such systems may add benefit to current dye removal methods from textile industry wastewater.

The textile industry is an industry that consumes large amounts of water during production, contains various chemicals in its wastewater, conventional treatment methods are insufficient to reduce the wastewater pollution level, and has colloidal substances and color problems. Membrane bioreactor systems provide high efficiency in the treatment of textile wastewater and dyestuff removal. Removal of dyestuffs and turbidity in real textile wastewater by using a laboratory-scale membrane bioreactor system was studied. Chemical precipitation was not applied before the biological treatment for the removal of color and other pollutant parameters. A hollow fiber microfiltration membrane module was used in the system. Then a combination with an active carbon filter was created to take the color removal to a higher level. The development of the microorganism composition adapted to the textile industry was observed in the biological reactor. The system was operated with an endless sludge age and a hydraulic retention time of 24 hours. Color measurement transparency index parameter DFZ (DurchsichtsFarbZahl) was measured in a spectrophotometer at wavelengths of 436, 525, and 620 nm (nanometers) according to EN ISO 7887 standards. In the microfiltration permeate water, the color removal were found in 436 nm: 91-95%, 525 nm: 94-98%, 620 nm: 96-99%, and in activated carbon permeate water, the color removal in 436 nm: 96-99% at 525 nm: 95-99%, 620 nm: 96-99%, respectively. Due to the physical separation of the membrane, which is the simplest definition, high efficiencies in color removal have been achieved in the system. The activated carbon system combined with the membrane was found higher efficiency in color removal than the microfiltration output.
