Aim: This study aimed to evaluate effectiveness of the coagulation process for reactive blue 19 dye (RB19) removal from textile industry wastewater. Besides, textile finishing's wastewaters, especially dye-house effluents, contain different classes of organic dyes, chemicals and . positive side, dyes can give beautiful color to various products, and therefore they are widely used in many fields such as textiles, paper, plastic, food, painting, and medicine (Altinisik et al., 2010; Safa and Bhatti, 2011). 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. In-plant control for waste reduction. 3 Textile industry is one of the biggest consumer of potable water as . Reactive dyes are one of the most used dyes which are recalcitrant to conventional treatment processes. Textile Dyeing Wastewater Treatment Zongping Wang, Miaomiao Xue, Kai Huang and Zizheng Liu Huazhong University of Science and Technology China 1. 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. Textile industrial wastewater pollution is a particular threat to water resources and a growing economy. 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 Crossflow ultrafiltration using GN polymeric membrane was used to remove the dye from textile effluent. REMOVAL OF COD AND COLOUR FROM TEXTILE WASTEWATER USING 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. 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. Approximately 1-10% of pigments used in paper and leather industries are lost as waste. These compounds contaminate the surface water, thereby making it unfit for irrigation and drinking. The total dye consumption of the textile industry worldwide is more than 10 7 kg/year [3] . 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. Such effluents must be treated to meet discharge limits imposed by the Water Framework Directive in Turkey. 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. Dye removal from textile wastewater has been a big challenge over the last decades. Effluent from the textile industry contains toxic compounds. Approximately 8-20% unutilized dyes and auxiliary chemicals are discharged into the wastewater stream from textile dyeing operations 3. Preliminary studies show that the wastewater from this homemade textile industries contains grease, wax, heavy metal, surfactant, suspended solid, and dyes (organic and inorganic). Apart from textile industry, they are also used in tannery, paper and pulp, pharmaceutical, food, paint, plastics, cosmetics and electroplating industries. The textile, pulp and paper industries are reported to utilize large quantities Consequently, the textile and dyeing industry has begun seeking efficient methods for the removal of dyes. A synthetic textile effluent of Direct-15 dye was used. The textile industry is characterized by the fact that its activity requires a high consumption of water, energy and auxiliary chemical products. The effect of parameters including type of surfactant, pH of solution, surfactant concentration, and amount of salt, was . iv CHAPTER THREE : LITERATURE REVIEW 3.1 Wastewater from Textile Industry 17 3.2 Textile Wastewater, Characteristics and Environmental Impact 18 . Copper is toxic to aquatic plants increasingly high standard. Among the treatment technologies, adsorption is an attractive and viable 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 . 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. Effluent from the textile industry contains toxic compounds. 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). The textile industry effluents which are discharged are treated with Effluents from textile industries are dye wastewater, and disposal of these wastes to freshwater bodies causes damage to the environment. Chitin was prepared Similarly, only 60 % of industrial wastewater, mostly large-scale industries, is treated. Dyes are using in several industries, like paper-making, textiles, plastic and foods industries. Excl- usive treatment by one of these three methods has proved to be insufficient in removing color and other effluent from textile industry wastewater. 2. Most of existing process includes an initial step of activated sludge treatment to remove the organic matters, followed by oxidation, membrane, activated carbon etc. The main purpose of this study was to investigate the effectiveness of Lactobacillus 12 and Lactobacillus rhamnosus as both cells and biomasses for the removal of dye from real textile dyeing wastewater. 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. To reduce water contamination, different sustainable methods have been employed in textile wastewater treatment in the wet processing industry.
