Evaluation of a novel electrochemical pilot plant process for azodyes removal from textile wastewater

Electrochemical treatment of simulated industrial paint wastewater in a continuous tubular reactor

“…Many researchers had investigated the electrochemical oxidation of various types of wastewater containing 1,4-benzoquinone [5], phenol [6][7][8][9], olive oil [10,11], vinasse [12], p-chlorophenol and p-nitrophenol [13], dichloromethane [14], 2-naphtol [15], ammonia [16], cadmium [17,18], nuclear wastes [19], human and domestic wastes [20,21], tannery wastewater [22,23] and textile wastewater [24][25][26][27][28], and metal recovery [29].…”

Optimization of electro-oxidation process for the treatment of Reactive Orange 107 using response surface methodology

“…These anions together with other ionic degradation products cause the increase of the current; however, NaCl enhances the decoloration process (Sakalis et al 2005). It is wellknown that the decoloration process proceeds mainly by direct redox reactions on the electrodes and enhanced by indirect redox reactions by the produced oxidants or reductants.…”

“…In most cases, high concentrations of supporting NaCl electrolyte is required for satisfactory results leading to high concentrations of hypochlorite anions and free chlorine (Naumczyk et al 1996). However, the use of NaCl involves Table 5 Analysis of variance (ANOVA) of the fitted quadratic model for color and COD removal the possibility of the formation of organochlorine compounds, mainly due to the presence of OCl − as a possible reaction (Sakalis et al 2005). At low salt concentration, the color removal efficiency was found to decrease with increase in pH whereas at high salt concentration the color removal efficiency increases with increasing pH.…”

“…4 a-c The effect of pH, electrolyte concentration, and time on COD removal cyclic and aliphatic hydrocarbons as intermediates (Sakalis et al 2005).…”

Degradation of Reactive Black 5 and Basic Yellow 28 on Metallic-Polymer Composites

“…The treatment of colored wastewater is commonly carried out using biological [1][2][3][4][5] and physico-chemical methods [6][7][8][9][10][11][12][13]. The use of electrochemical techniques for the study and removal of color and organic load from model colored solutions [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32] and industrial wastewater has received great attention in the last years [3,[14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][...…”
