“…The discharge limit for phenol as prescribed in sewerage and drainage regulations is 0.5 mg/lit (Jenkins, 1982). Phenol containing effluents is generated from several industries such as steel plants and coke production units (Das et al, 2018). Effluents emanating from food processing industries like olive mills wastewater, olive wastewater, winery, and distillery wastewater also bear phenol in different concentrations.…”

In recent years, the domain of the research space in novel separation process has been led by membrane systems as a panacea providing multifarious benefits of high separation efficiency, elimination of extreme process conditions, sustainability, and environment friendliness coupled with high operational flexibility. In this niche area, often, ultrafiltration is touted as a robust separation technique due to its high separation efficiency, membrane stability, and lower operating costs. The only drawback of relatively large pore size can be overcome by combining surfactant addition, leading to development of integrated processes termed as Micellar Enhanced Ultrafiltration. MEUF processes isolate and selectively separate valuable organics present in effluent streams.The process characteristics fit the bill as a typified example for process intensification Technology interventions for recycling of surfactants can enhance the cost-competitiveness of the process. This has the potential to develop into a broad-spectrum effluent treatment option with a change of surfactants for target contaminants. Here, in this review, we attempt to critically examine the unique features of this technology, development of spin-offs with wide-ranging applications. Specifically applications in removal of hazardous, and persistent components like dissolved organics have been critically studied. The focus was to highlight the crux of the novel technologies highlighting the efficacy and the underlying concept of process intensification. Practitioner Points• Role of MEUF as a sustainable process intensifying separation technique for removal and recovery of organics.• Novel process development using MEUF.• Comparative performance analysis to assess efficacy.• Discussions on future integrative process development.• Sustainability aspect of MEUF with possibility of byproduct recovery.

“…Iron and steel plants, for example, often consist of a variety of operations, 11 each of which may generate distinct wastewater constituents. 53 Coke ovens, associated with coke production, produce substantial quantities of wastewater effluent containing high concentrations of cyanides, phenol, ammonia, thiocyanate, and oil. 54 Blast furnaces also account for a significant share of wastewater production, contributing thermal pollution and copious suspended solids, ranging from 1000 to 5000 mg/L.…”

As the impact of water scarcity in the United States (U.S.) continues to grow through the 21st century, it is critical to develop strategies to reduce water use and improve the security of water resources. One such strategy is to diversify the sources from which water is supplied. Industrial withdrawals represent the fourth largest category of U.S. water use, the majority of which is sourced from fresh surface and groundwater. In this study, we critically explore the potential of industrial wastewater to serve as an alternative water resource through direct treatment and reuse. We begin by reviewing the state of the art of water use, treatment, and reuse across six representative industries: food and beverages, primary metals, pulp and paper, petroleum refining, chemicals, and data centers and campuses, highlighting key challenges and opportunities toward the expansion of reuse. We then employ a technoeconomic assessment of water treatment processes to analyze the capital investment, operating and maintenance costs, levelized cost of water, and electricity consumption of three specific industrial plants as case studies to better understand where research can promote impactful innovation. Finally, drawing together the results of our literature review and technoeconomic analyses, we provide a broad outlook on the future of industrial water reuse and discuss strategies for its expansion.

“…Notwithstanding its significance, few studies have focused on the disposal of coke oven effluent (Das et al 2018 ). This work presents a case study on ion exchange technology to reduce fluoride content (C 0 = 26.70 mg F - /L) in the effluent of a coke wastewater treatment plant (ECWT) to acceptable limits.…”

Coke wastewater is one of the most problematic industrial wastewaters, due to its large volume and complex pollutant load. In this study, ion exchange technology was investigated with the objective of reducing the fluoride content of the effluent from a coke wastewater treatment plant (26.7 mg F-/L). Two Al-doped exchange resins with chelating aminomethyl-phosphonic acid and iminodiacetic groups were assessed: Al-doped TP260 and TP207 resins, respectively. The effect of resin dosage, varying from 5 to 25 g/L, was evaluated. F- removal was within the range 57.8–89.3% and 72.0–92.1% for Al-doped TP260 and TP207, respectively. A kinetic study based on a generalized integrated Langmuir kinetic equation fitted the experimental data (R2 > 0.98). The parameters of the said kinetics met the optimal conditions for the ion exchange process, which seemed to be more favorable with Al-doped TP260 resin than with Al-doped TP207 resin, using the same resin dosage. Furthermore, the experimental data were well described (R2 > 0.98) by Langmuir and Freundlich isotherm models, in agreement with the findings of the kinetic study: the maximum sorption capacity was obtained for the Al-doped TP260 resin.
