BACKGROUND: Textile industries generate considerable amounts of waste-water, which may contain strong colour, suspended particles, salts, high pH and high chemical oxygen demand (COD) concentration. The disposal of these coloured wastewaters poses a major problem for the industry as well as a threat to the environment. In this study, electrochemical oxidation of Basic Blue 3 (BB3) dye was studied in a bipolar trickle tower (BTT) reactor using Raschig ring shaped boron-doped diamond (BDD) electrodes in recirculated batch mode. The effects of current density, temperature, flow rate, sodium sulfate concentration (Na 2 SO 4 ) as supporting electrolyte, and initial dye concentration were investigated.

“…Various types of treatment processes that can be used to treat the dye-containing wastewater are physicochemical and biological processes. Physical processes include adsorption (Amin 2008;Anjaneyulu et al 2005;Malik 2003;Velmurugan et al 2011) and membrane filtration (Patel and Nath 2012;Petrinic et al 2007) processes. Chemical processes include coagulation-flocculation (Wong et al 2007;Golob et al 2005) and ozonation (Taplad et al 2008;Inaloo et al 2011).…”

Dyes are synthetic organic compounds widely used in various industries such as, textile, leather, plastic, food, pharmaceutical, and paints manufacturing industries. Coloured effluents are highly toxic to the aquatic life and mutagenic to humans. Wastewater containing dyes has become an important issue demanding serious attention. Among the synthetic dyes, azo dyes are the largest and most widely used dyes and account for more than half of the annually produced dyes. The biodegradation of azo dyes is difficult due to their complex structure and synthetic nature. Several treatments have been proposed for efficient azo dye removal, most of them presenting some limitations such as generation of waste sludge, high operational costs, poor efficiency, and incomplete mineralization. Biological treatment is a cost-effective and eco-friendly process for dye degradation. Sequential anaerobic-aerobic biological treatment is considered as one of the most cost-effective methods for the complete mineralization of azo dyes. The anaerobic stage yields decolourization through reductive cleavage of the dye's azo linkages, resulting in the formation of generally colourless but potentially hazardous aromatic amines. The aerobic stage involves degradation of the aromatic amines. It is the most logical step for removing the azo dyes from the wastewater. Several factors can influence the microbial activity and consequently the efficacy and effectiveness of the complete biodegradation processes. This paper summarizes the results of biological decolourization of azo dyes using various types of reactors, elaborates biochemical mechanisms involved, and discusses influence of various operational parameters on decolourization based on reports published in the last decade.

“…As a result, this effluent is some of the most difficult industrial wastewater to treat (Lotito et al, 2012;Nyström et al, 2004;Uzal, 2007). The wastewater contains fibres and large amounts of salts, acids or alkali chemicals from dyeing and finishing processes (Lotito et al, 2012;Capar et al, 2006;Fersi et al, 2005;Petrinic et al, 2007;Setiadi et al, 2003;Uzal, 2007). Furthermore, the composition of wastewater from textile processes varies greatly from day to day and hour to hour depending on the dyestuff, fabric and chemicals used.…”
