Zainal Abedin Abstract: Use of various dyes in order to color the products is a common practice in composite knit industry. Wastewater treatment in textile and dye industry mainly involves treatment of highly colored wastewater containing variety of dyes in different concentrations. In this study, a combined two-stage water reuse treatment was established to enhance the quality and recovery rate of reused water. The textile industry effluents which are discharged are treated with 3 Textile industry is one of the biggest consumer of potable water as . The . Dyeing process usually government legislation is forcing textile contributes chromium, lead, zinc and copper to industries to treat their waste effluent to an wastewater [10]. 2. Textile dyeing processes are among the most environmentally unfriendly industrial processes, because they produce colored wastewaters that are heavily polluted with dyes, textile auxiliaries and chemicals [1]. This has to be treated properly before releasing into nature. Aim: This study aimed to evaluate effectiveness of the coagulation process for reactive blue 19 dye (RB19) removal from textile industry wastewater. Textile Industry: Responsible for Up to 20% of All Industrial Wastewater August 24, 2021 Textile dying is one of the most polluting industries, consuming 21 trillion gallons of water annually to be mixed with textile colorants, and then disposing of nearly an equivalent amount (enough to fill 37 million olympic sized swimming pools, or about 20% of all industrial wastewater). In the textile wastewater, dye is considered the color imparting component which is difficult to treat by conventional processes. Effluent from the textile industry is the chief contribution to water pollution. A synthetic textile effluent of Direct-15 dye was used. However, the waste water from industries using dye may still contain up to 15 % of the dye (Moussavi and Khosravi, 2011). 3. Biological methods are generally cheap and simple to apply and are currently used to remove organic and color from dyeing and textile wastewater. Textile Dyeing Wastewater Treatment Zongping Wang, Miaomiao Xue, Kai Huang and Zizheng Liu Huazhong University of Science and Technology China 1. Most of existing process includes an initial step of activated sludge treatment to remove the organic matters, followed by oxidation, membrane, activated carbon etc. This study inspects the possible use of chitin for the removal of dye from textile wastewater. During the processing of textile, a lot of dyestuff specifically lost to the wastewater due to inefficiency in dyeing processes which may causes serious health and environmental problems. The experiment results of colour removal in a textile industrial wastewater using Lemna minuta L. were verified with the colour removal in an aqueous solution using Lemna minuta L. for their reproducibility. difficult tasks confronted by the wastewater treatment plants of textile industries is the removal of colour of these compounds, mainly because dyes and pigments are designed to resist biodegradation, such that they remain in the environment for a long period of time. dyestuff industries are difficult to remove.

Textile and dyeing industry are the essential industries in the present scenario and have become one of the major sources of water pollution. The textile industry generates huge quantities of complex chemical substances as a part of unused materials including dyes in the form of wastewater during various stages of textile manufacturing and processing. The dyes are washed off during the dyeing process, thus, the residual dyes always present in the dye bath effluent and may be as much as 50% (reactive dyes) of the initial dye load (Parsons, 2004; Wilas et al. 2017 . Effluent from the textile industry contains toxic compounds. To solve the problems of treatment of waste-waters from a textile plant, several alternatives should be included. 02, Issue 05, October 2014. Int aste Resour 8: 330. doi: 10.412/2252-5211. Thus, the objective of this study was the investigation of the influence of functional parameters of electrocoagulation, such as pH, amount of electrolyte and applied potential, in the removal of dye color of aqueous solution. 4. ao Ouslimani N Boureghda MZM (2018) Removal of Directs Dyes from Wastewater by Cotton Fiber aste. Besides, textile finishing's wastewaters, especially dye-house effluents, contain different classes of organic dyes, chemicals and . Dyeing process normally uses large amount of water for dyeing, fixing and washing processes. 2.1.4 Pretreatment of Fabric for Dyeing and Finishing 10 2.1.5 Dyeing 11 2.1.6 Printing 12 2.1.7 Finishing 13 2.2 Sources of Pollution 14 . The majority of the waste water comes from the dyeing and finishing process. Wastewater from the textile finishing industry commonly contains moderate concentrations (10 - 200 mg/l) of dyestuffs, contributing significantly to the pollution of aquatic ecosystems. A synthetic textile effluent of Direct-15 dye was used. The removal experiments were conducted according to the Box-Behnken experimental design, and the regression equations for the removal of dye were determined by the Minitab 14 program.

(1998) "Treatment and Reuse of wastewater from the textile Wet-Processing Industry: Review of Emerging Technologies", Journal of Chemical Technology & Biotechnology, Vol. The textile industry requires very large quantities of water during manufacturing and processing procedures, being major consumer of water [].This industry uses about 10,000 different dyes, and more than 0.7 Mt of these dyes are annually produced worldwide [].Ten to fifteen percent of these dyes are released to the environment which constitutes one of the biggest environmental problems of the . Meanwhile, there are various treatment processes that have been investigated and employed extensively for dyes elimination from wastewater [ 8 , 9 ], including coagulation and flocculation [ 10 Approximately 8-20% unutilized dyes and auxiliary chemicals are discharged into the wastewater stream from textile dyeing operations 3. This is translated into the generation of a large amount of wastewater, with high concentrations of dyes, biodegradable and refractory organic pollutants, suspended matter, surfactants, salts and chlorinated compounds. 17 -20% of industrial freshwater pollution is caused by textile dyeing and treatment. 2 Materials and Methods Among the treatment technologies, adsorption is an attractive and viable Adsorbent is very useful as it can remove the dye from the textile. 1000330 Page 2 of 8 oe 8 e 2 33 ae eo a oe ae oa 225252 color is a very important physiological factor in the pollution [12,13] these are the most typical in the textile finishing industrial emissions. A study was conducted on "Color/Dye Removal from a Textile Industry Effluent Using Activated Carbon" In this study removal by adsorption of various acidic, reactive and direct dyes on two different samples of Granular Activated Carbon was observed in Static Batch Method as well as Continuous Flow Process. Since farmers use water from the rivers for agricultural purposes and the residents of the town, use both the surface and underground water from the same area as potable water, it is quite unsafe to discharge this effluent into water body. Release of textile industries waste especially their dying effluent impose a serious pollution on the environment. The treatment of this colored wastewater is of great concern nowadays, because many dyes and their degradation Indian researchers have developed an "improved" wastewater treatment solution that can completely reuse dye wastewater from the textile industry, eliminating its toxicity and making it suitable . Effluent treatment methods can be classified into phy- sical, chemical and biological methods; (Table 3). The wastewater needs to be treated prior to discharge by effectively removing dye color in order to protect environment and as per the statutory guidelines. Consequently, the textile and dyeing industry has begun seeking efficient methods for the removal of dyes. A study on removal of commercially used reactive dye was conducted to investigate the effectiveness of coagulation-flocculation from textile wastewater. iv CHAPTER THREE : LITERATURE REVIEW 3.1 Wastewater from Textile Industry 17 3.2 Textile Wastewater, Characteristics and Environmental Impact 18 . This particular type of wastewater is a complicated mixture of dyes, surfactants, inorganic and organic salts, polymers, oligomers, and stabilizing agents with other recalcitrant organics such as alcohols, aldehydes, and organic acids. Ultrafiltration membrane was used to treat the effluent from textile industries. The cotton textile industry is one of the Preliminary studies show that the wastewater from this homemade textile industries contains grease, wax, heavy metal, surfactant, suspended solid, and dyes (organic and inorganic). Introduction Industrialization of the textile industry and use of a large variety of chemical treatments and dyes has resulted in a public health threat created by pollution. Ultrafiltration membrane was used to treat the effluent from textile industries. 1000330 Page 2 of 8 oe 8 e 2 33 ae eo a oe ae oa 225252 color is a very important physiological factor in the pollution [12,13] these are the most typical in the textile finishing industrial emissions. The reduced natural waters and the large amount of wastewater produced by textile industry necessitate an effective water reuse treatment. Adsorption of dyes Adsorption techniques are used as high quality treatment processes for the removal of dis‐ solved organic pollutants, such as dyes, from industrial wastewater. Electrochemical reduction reactions are mostly used in sulfur and vat dyeing, but in some cases, they are applied to effluents discoloration. SEPARATION PROCESSES . Reactive dyes are one of the most used dyes which are recalcitrant to conventional treatment processes. The GO nanosheets produced were compared with commercial graphene and characterized by X-ray diffractometry (XRD), Raman spectroscopy, specific surface area analysis, and zero-charge point (pHpcz). An estimated 38354 million litres per day (MLD) sewage is generated in India′s major cities, but the sewage treatment capacity is only of 11786 MLD. This research can input useful information on the reuse of agricultural wastes as effective agro-wastes dye adsorbent on related industries. Azo dyes are largely utilized in textile industry as coloring agent. Int aste Resour 8: 330. doi: 10.412/2252-5211. Dye industry for instance is identified as the tenth most polluting industry to the water in rivers, as 17-20% of the industrial water pollution is contributed by the textile dyeing and treatment 1. Textile industrial wastewater pollution is a particular threat to water resources and a growing economy. Vol 24 (2) . Effluent from the textile industry contains toxic compounds. Textile wastewater includes a large variety of dyes and chemical which get remains in to the bath and create drainage. There are more than a hundred textile industries in Turkey that discharge large quantities of dye-rich wastewater, resulting in water pollution. The study focused through the effect of feed concentration, transmembrane pressure and solution's pH on the permeate flux and percentage of dye removal . Dyes are using in several industries, like paper-making, textiles, plastic and foods industries. 2 Water is the main component used in all type of industries Water used for different processes is not completely utilized & is discharged as wastewater Introduction. The textile industry is characterized by the fact that its activity requires a high consumption of water, energy and auxiliary chemical products. In order to remove dyes from wastewater, different researches The textile industry produces 5000 tons of dyeing materials that are discharged into the environment every year [4]. Granular activated carbon (GAC) did not show any significant adsorption ability on the disperse dyes, while resting (living) bio-sludge of a domestic wastewater treatment plant showed high adsorption abilities on both disperse dyes and organic matter. Therefore, removal of dyes from textile wastewater is necessary prior to their disposal. 3 1. REMOVAL OF COD AND COLOUR FROM TEXTILE WASTEWATER USING 119, pp.14-18. Title: Removal of colour from textile wastewater by different methods ijaerdv04i0791076n, Author: Editor IJAERD, Name: Removal of colour from textile wastewater by different methods . About 200-350 m 3 of wastewater per ton of finished products are regular volumes of textile industry where large amounts of dyes are used Pin04, Rob01. Various physico-chemical and biological techniques can be employed to remove dyes from wastewaters. hence, the decolourisation of textile industry wastewater before being discharged onto the land. Wastewater from printing and dyeing units is often rich in color, containing residues of reactive dyes and chemicals, and requires proper treatment before being released into the Therefore, the main aim of this article is to provide a complete survey about different wet processing steps in cotton textile industry and the cost of methods implemented for the treatment of the dyes in textile wastewater. Discharge of colored wastewater from various industries like textile, dying, food processing, leather, cosmetics, and paper industries and so on, is a major problem for environmental management particularly in developing countries [1]. While some dyes are difficult to biodegrade few, particularly the . only in textile wastewater but also in any kind of complex matrix (Ding et al., 2010). B. T. Pelosi I; L. K. S. Lima II; M. G. A. Vieira III, *. "The research focused on toxic dye removal because it is a persistent challenge for the textile industry," Ramkumar noted. Treatment to 'reuse standard' on an external (end-of-line) basis or by closed-loop recycle systems. dye stuff poses a major problem to industrial wastewater effluents [3]. Dyes consider as type of organic pollutants. These compounds contaminate the surface water, thereby making it unfit for irrigation and drinking. The dye adsorption ability of bio-sludge increased by approximately 30% through acclimatization with disperse dyes, and it decreased by . The major classes of dyes according to their dyeing process in textile finishing are acid dyes, basic dyes . ao Ouslimani N Boureghda MZM (2018) Removal of Directs Dyes from Wastewater by Cotton Fiber aste. Textile dye removal from wastewater effluents using bioflocculants produced by indigenous bacterial isolates Bioflocculant-producing bacteria were isolated from activated sludge of a wastewater treatment plant located in Durban, South Africa, and identified using standard biochemical tests as well as the analysis of their 16S rRNA gene sequences. 143-151. 8 The improper discharge of colored dye effluents into natural water bodies severely affects all living forms and causes aesthetical unpleasantness creating a significant problem to human being. Approximately 1-10% of pigments used in paper and leather industries are lost as waste. Removal of the synthetic dye Remazol Brilliant Blue R from textile industry wastewaters by biosorption on the macrophyte Salvinia natans. An ideal dye removal method should be able to efficiently remove large quantities of dye from wastewater in a short time span without producing secondary pollution. Currently, removal of at concentrations below 1.0 mg/l while dyes from effluent is done by physico-chemical . The effect of parameters including type of surfactant, pH of solution, surfactant concentration, and amount of salt, was . The textile effluent treatment involves mainly physical, chemical and biological methods. The textile dyeing industry consumes large quantities of water and produces large volumes of wastewater from different steps in the dyeing and finishing processes. Excl- usive treatment by one of these three methods has proved to be insufficient in removing color and other effluent from textile industry wastewater. Such effluents must be treated to meet discharge limits imposed by the Water Framework Directive in Turkey. Abstract: In this work the ability of "bleached" oil mill solid waste to reduce the dyestuff content in industrial textile wastewater was studied.Bleaching treatment consists in a preliminary oil mill solid waste management with NaOH and NaClO2 for obtaining cellulosic . Textiles is one of the largest industries in the world. 3. Dye removal from textile wastewater has been a big challenge over the last decades. "Removal of dissolved textile dyes from wastewater by a compost sorbent", Coloration Technology, Vol. Three types of coagulants were studied;. The manufacturing of textiles can take up to 200 tons of fresh water per ton of dyed fabric, so inevitably there is a vast amount of wastewater produced as a result of the process. Similarly, only 60 % of industrial wastewater, mostly large-scale industries, is treated. To reduce water contamination, different sustainable methods have been employed in textile wastewater treatment in the wet processing industry. It produces almost 20% of the world's wastewater. The total dye consumption of the textile industry worldwide is more than 10 7 kg/year [3] . TEXTILE INDUSTRY . making it an interesting option for dye removal from industrial effluents. The synthesis of graphene oxide (GO) nanosheets, to be used as an adsorbent for the removal of textile dyes from wastewater, was optimized by the modified Hummers method.
