Parametric and multiple response optimization for the electrochemical treatment of textile printing dye-bath effluent

Synthesis and application of green mixed-metal oxide nano-composite materials from solid waste for dye degradation

“…Solid waste sludge was obtained from EC treatment of dye. Details are given in previous publication (Mondal et al, 2013;Singh et al, 2013cSingh et al, , 2013bSingh et al, , 2014b.…”

Multi-Response Optimization of Parameters for the Electrocoagulation Treatment of Electroplating Wash-Water using Aluminum Electrodes

“…Increase and decrease in pH from pH 7 lead to an increase in specific energy consumption and specific operating cost. This is due to the fact at these pH, removal takes place by dual mechanism of charge neutralization by Al(OH) 4 -and sweep coagulation by precipitated Al(OH) 3 which trap the metals effectively (17,36). Among all responses, pH was found to have higher impact on Y 1 and Y 2 and minor impact on Y 3 , Y 4 and Y 5 .…”

“…EC of EWW was optimized for maximizing the Y 1 , Y 2 and Y 3 while minimizing the Y 4 , Y 5 simultaneously using the procedure given in detail in our previous studies (15)(16)(17)37 …”

“…Common among them are aluminum and iron electrodes due to their easy availability and less cost (12). EC treatment has been used previously for treatment of a variety of industrial wastewaters and for the removal of a variety of pollutants (13)(14)(15)(16)(17)(18).…”

Delineamento Box-Behnken para remoção de DQO de efluente têxtil utilizando eletrocoagulação com corrente contínua pulsada

“…Além disso, outra desvantagem do processo é a concentração remanescente de sólidos dissolvidos no efluente tratado (DASGUPTA et al, 2015). Os processos de adsorção são demorados e caros devido à utilização de adsorventes comerciais (MONDAL et al, 2013). Para a aplicação da degradação biológica é necessário um pré-tratamento para a remoção de corantes tóxicos (PI et al, 2014).…”
