“…In recent years, electrocoagulation (EC) of synthetic or real oily water has been investigated by some researchers (Ruback and Saur, 1997;Dórea et al, 2007;Tir and Mostefa, 2008;Canizares et al, 2007;Benzadok et al, 2008;Asselin et al, 2008;Abdelwahaba et al, 2009;Ramalho et al, 2010;Lima et al, 2009;Cerqueira et al, 2011). During electrolysis, four main mechanisms generally occur simultaneously: (a) electrolytic reactions at the electrode surfaces, (b) formation of coagulant agents in the aqueous phase, (c) adsorption of soluble or colloidal pollutants by these agents and (d) removal by sedimentation or flotation.…”

“…It was reported that reaction 6 could also occur in acidic conditions at high current densities (29). The process of RO oxidation proceeds continuously by the formation of hydroxyl radicals via anodic discharge of water molecules (9,22,(27)(28)(29)(32)(33)(34).…”

“…The chlorohydroxyl radicals adsorb simultaneously on the active sites of the anode surface S, and then oxidize the organic matter R (9,22,(27)(28)(29)33,34).…”

“…A aplicação do tratamento eletroquímico a efluentes industriais apresenta uma evolução relativamente recente, sendo bastante atrativa por apresentar características como facilidade de automação, maior eficiência e versatilidade em um menor tempo de tratamento, além de requerer menor espaço físico para suas instalações, permitindo operar com uma infraestrutura mais compacta [4][5][6][7][8][9][10][11][12][13][14]. Uma das maiores vantagens do tratamento eletroquímico é a diminuição no uso de produtos químicos para o tratamento [5, 9,13,[15][16][17].…”

“…Uma das maiores vantagens do tratamento eletroquímico é a diminuição no uso de produtos químicos para o tratamento [5, 9,13,[15][16][17]. Outra importante vantagem é a possibilidade de uma eficiente mineralização de compostos orgânicos não biodegradáveis, além do alto potencial de desinfecção [7,16].…”
