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.

“…However, the main drawback in NF process of dye solutions is the fouling problem, which results in an undesirable flux decline. According to Al-Bastaki [17], the extent of dye adsorption on membrane surface and its reversibility are determined by the factors of dye-membrane physicochemical interactions which in turn depend on the feed water chemistry as well as the operating conditions. The fouling phenomena however could be diminished with using a strongly negatively charged NF and/or with an adequate membrane cleaning process [3,6].…”

A B S T R A C TThree different characteristics of self-made hollow fiber nanofiltration (NF) membranes with different structural and electrical properties were evaluated for their suitability for removing salt and colour as a function of feed conditions. Results showed that NF achieved promising dye retention for the reactive dyes used at different concentrations and varied slightly with pH. The retention of salt was found to be dependent on feed properties and membrane electrical properties where higher retentions were achieved under alkaline condition and by using the most negatively charged NF membrane. The enhancement in the membrane negative surface charge resulting from the addition of sulfonated poly (ether ether ketone) (SPEEK) during membrane preparation had also made the NF less fouling-sensitive to dye absorption and improving the economic viability of the treatment process.

“…A variety of filtration techniques, such as sand filtration and membrane filtration (including microfiltration, ultrafiltration, and reverse osmosis (RO)) are effective at removing most contaminants from waste water [210][211][212]. Filtration works by trapping contaminants between pore spaces within the filter, making it a very sizedependent removal process.…”
