Electrochemical treatment of simulated textile wastewater with industrial components and Levafix Blue CA reactive dye: Optimization through response surface methodology

Electrocoagulation in Wastewater Treatment

“…Körbahti and Tanyolaç concluded that 100% pollution load, 61.6% COD, 99.6% color removal, and 66.4% turbidity were accomplished by an electrochemical reactor, where optimum conditions for conducting the experiment were at temperature of 30 degrees Celsius, 25 g/L electrolyte concentration, 8 V electrical potential, with a 35.5 mA/cm 2 current density. This was accomplished to treat simulated textile dye wastewater with NaCl electrolyte based on response surface methodology [6]. Hammami et al concluded that electrochemical oxidation of chromium(III) from chromium(VI) was accomplished with titanium-platinum anodes for the purpose of treating tanning bath effluent.…”

“…Boroski et al concluded that electrocoagulation filtration combined photocatalysis using a UV/TiO 2 /H 2 O 2 systems improved the biodegradable index (BOD/COD) from 0.48 after electrocoagulation to 0.89 with the use of the hybrid system, using 6 [110]. Canizares et al concluded that the use of a boron doped diamed (BDD) anode for soluble organic matter mineralization was capable of breaking down metalworking wastewater by physio-chemical processes using an electrochemical reactor [111].…”

Coagulación natural para la descontaminación de efluentes industriales

“…Se ha contabilizado que por cada kilogramo de producto procesado, esta industria desecha hasta 150 L de agua residual (Korbahti & Tanyolac, 2008). En promedio, al año se producen 8x10 5 toneladas métricas de colorantes, de los cuales el 50% son del grupo químico azo (Bouasla, Ismail, & Samar, 2012).…”

Biodegradation of BTEX: Optimization through Response Surface Methodology

“…Thus, through the use Response Surface Method (RSM), one can optimize all the major parameters and eliminate the limitations of oneparameter optimization (Choudhury and El-Baradie, 1999). RSM has been used in various fields such as machining techniques (Choudhury and El-Baradie, 1999), chemical reactions (Sultania et al, 2011;Setiabudi et al, 2013) enzyme and catalytic reactions (Hosseinpour et al, 2011;Thouchprasitchai et al, 2011;Yüksel and Yeşilçubuk, 2012) and with recent broader application extended to the optimization of water and water treatment processes (Güven et al, 2008;Körbahti and Tanyolaç, 2008;Trinh and Kang, 2011;Kumar and Pal, 2012;Yuliwati et al, 2012), in biochemistry (Wang et al, 2012) toxicology studies (Carter et al, 1985;Kiran and Thanasekaran, 2011;Jeong et al, 2012) and in biotechnology for studying biodegradation of phenol (Sheeja and Murugesan, 2002). However, a limited number of studies (Jo et al, 2008;Jin et al, 2013) were reported on the optimization of BTEX's removal efficiency.…”
