Being one of the leading industries worldwide, the textile industry has been consuming large quantities of groundwater and discharging huge volumes of dye-contaminated effluents into our aquatic environment. Augmentation of water sources via reuse of treated effluents is therefore highly necessary. In the present study, the decolorization and degradation of synthetic toxic dye from an aqueous solution were investigated through an electro-biological route. Initially, decolorization of synthetic dye solutions (100, 500, and 1000 mg L⁻¹) was carried out by electrooxidation process using mixed metal oxide and titanium as anode and cathode, respectively. The electrooxidation solutions were further treated using bacteria (Pseudomonas aeruginosa) that were isolated from petroleum-transporting pipelines. UV–Vis, TOC, chemical oxygen demand, and NMR analyses revealed that the biodegradation process with electrooxidation enhanced the mineralization of the synthetic dye solutions. An optimum NaCl electrolyte concentration of 3 g L⁻¹ was sufficient to produce reactive species viz., free chlorine and hypochlorite, which are responsible for the Reactive Blue 19 (RB-19) decolorization. Among the three RB-19 concentrations, the highest removal percentage was noticed at 100 mg L⁻¹ (100%) with energy consumption and energy costs equal to 5.44 kWh m⁻³ and 0.65 USD m⁻³, respectively.

作为全球领先的行业之一，纺织行业一直在消耗大量地下水，并向我们的水生环境排放大量受染料污染的废水。因此，非常有必要通过再利用处理过的废水来增加水源。在本研究中，通过电生物途径研究了水溶液中合成有毒染料的脱色和降解。最初，合成染料溶液（100、500 和 1000 mg L ^-1）的脱色通过分别使用混合金属氧化物和钛作为阳极和阴极的电氧化工艺进行。使用细菌（铜绿假单胞菌）进一步处理电氧化溶液) 从石油运输管道中分离出来的。UV-Vis、TOC、化学需氧量和 NMR 分析表明，电氧化的生物降解过程增强了合成染料溶液的矿化。^{3 g L -1}的最佳 NaCl 电解质浓度足以产生活性物质，即游离氯和次氯酸盐，它们是活性蓝 19 (RB-19) 脱色的原因。在三个 RB-19 浓度中，去除百分比最高的是 100 mg L ^-1 (100%)，能耗和能源成本分别等于 5.44 kWh m ^-3和 0.65 USD m ^-3。
