Influence of different textile fibers on characterization of dyeing wastewater and final effluent Renan Felinto dos Santos & Heloisa Ramlow & Neseli Dolzan & Ricardo Antonio Francisco Machado & Catia Rosana Lange de Aguiar & Cintia Marangoni Received: 5 August 2017 /Accepted: 22 October 2018 # Springer Nature Switzerland AG 2018 Abstract Textile industry needs to recover and reuse its wastewater as to fulfil the demand of increasingly strict regulations. The characterization of dyeing wastewater samples according to textile fiber and final textile efflu- ent enables the application of different treatment methods. This study aims to characterize dyeing waste- water in black color of polyamide, polyester, and vis- cose fibers and final textile effluent. Samples were col- lected and characterized completely for major pollution indicator parameters. Dyeing wastewater of polyester showed higher values for some parameters, e.g., 4994.44% (49,944,400 mg L -1 and 917 NTU) of tur- bidity and 4100.00% of phenol when compared to dye- ing wastewater of other fibers. Other parameters such as pH, alkalinity, color, phosphorus, nitrogen, sulfides, chlorides, oil and grease, dissolved solids, and chemical and biochemical oxygen demand were also assessed. In addition to individual characterization, this study also presents a correlation of the contribution of each param- eter to the final textile effluent. Although dyeing waste- water of polyamide contributes the most in terms of quantity for the final effluent, this study revealed that dyeing wastewater of polyester influenced the most on the final composition of the textile wastewater when evaluating color, turbidity, total iron, biochemical oxy- gen demand, chemical oxygen demand, phenol, mercu- ry, oil and grease, and total phosphorus. The present study is focused on bringing new insights to provide future research with other strategies to improve the treatment of dyeing wastewater. In addition, some sug- gestions are also given for wastewater treatments ac- cording to type of textile fiber. Keywords Physicochemical parameters . Viscose . Polyester . Polyamide . Textile industry Introduction The textile industry represents one of the biggest indus- trial freshwater–consuming sectors, and it discharges a large quantity of wastewater. The disposal of wastewater has been a major environmental concern in recent de- cades (Güyer et al. 2016; Wu et al. 2017). Therefore, the textile industry has to reuse its wastewater in order to fulfil the demands of increasingly strict regulations. The dyeing process is the most severe type of water pollution by textile wastewater. The dyeing process consumes more than 100 L of water per kilogram of processed material and 80% of this volume is discarded as wastewater (Vajnhandl and Valh 2014). Wastewater from the dyeing process has common characteristics such as strong color, high pH, high chemical oxygen demand (COD), and low biodegradability (Wang et al. 2015).
