Real textile effluents treatment using coagulation/flocculation followed by electrochemical oxidation process and ecotoxicological assessment

Optimization of a cationic dye desorption from a loaded-lignocellulosic biomass: factorial design experiments and investigation of mechanisms

“…Scientific awareness has grown considerably in the last decades in order to find adequate and innovative methods for the treatment of this source of pollution. A large variety of techniques were accordingly investigated such as membrane separation [10], coagulation-flocculation [11], biological degradation [12] and electrochemical and advanced oxidation processes [13,14]. Despite the reportedly high purification yields of some of these techniques, they could necessitate the implementation of expensive operating plants, increased use of "already" polluting chemicals, and generating byproducts that might require further treatment.…”

Physico‐chemical processes

“…Torres et al (2019) evaluated the efficiency of TOC reduction and ecotoxicity mitigation of textile wastewater by applying the electrochemical oxidation method. The wastewater effluent was pretreated by coagulation‐flocculation process.…”

Multi-response optimization of the coagulation process of real textile wastewater using a natural coagulant

“…One of the major applications of coagulation can be found in textile industries (Torres et al, 2019) where large amounts of water are spent and substantial quantities of effluents are discharged. The quality and complexity of the effluent may vary depending on the processes involved at the various production stages, like bleaching, dyeing, printing, etc (Torres et al, 2019).…”

“…One of the major applications of coagulation can be found in textile industries (Torres et al, 2019) where large amounts of water are spent and substantial quantities of effluents are discharged. The quality and complexity of the effluent may vary depending on the processes involved at the various production stages, like bleaching, dyeing, printing, etc (Torres et al, 2019). Each of these processes contributes to the release of different types of persistent and non-biodegradable pollutants into the wastewater, making it hard to be treated (Jorfi et al, 2016;Dasgupta, Sikder, Chakraborty, Curcio, & Drioli, 2015).…”

“…Multiresponse optimization are employed, where a single optimum condition is determined for all responses simultaneously. Unlike other recent studies in the field (Torres et al, 2019), in this work all optimization experiments were conducted using real waste samples without purification or pre-treatment and no synthetic samples were used anywhere in this investigation.…”
