“…Their work was based on a new strategy to realize the sustainable use of inorganic salts from the landfill leachate reverse osmosis concentrate. Tang et al 41 employed BMEU to treat the concentrated brine obtained during reverse osmosis process for recover valuable resources and generate base-acid considering the impacts of working voltage, low velocity, feed concentration ratio, and unusual phenomena. The results indicated that the cost of the BMEU was around 10.54 YCH/kg NaOH (Sodium hydroxide).…”

Due to the high volume of wastewater produced from dairy factories, it is necessary to integrate a water recovery process with the treatment plant. Today, bipolar membrane electrodialysis units (BMEUs) are increasingly developed for wastewater treatment and reutilizing. This article aims to develop and evaluate (technical and cost analyses) a combined BMEU/batch reverse osmosis unit (BROU) process for the recovery of chemicals and water from the dairy wastewater plant. The combined BROU/BMEU process is able to simultaneously produce water and strong base-acid, and reduce power consumption due to the injection of concentrated feed flow into the BMEU. A comprehensive comparative analysis on the performances of two combined and stand-alone BMEU configurations are developed. The proposed combined technology for dairy factory wastewater treatment is designed on a new structure and configuration that can address superior cost analysis compared to similar technologies. Further, the optimal values of permeate flux and current density as two vital and influencing parameters on the performance of the studied dairy wastewater treatment process were calculated and discussed. From the outcomes, the total cost of production in the combined configuration has been reduced by approximately 26% compared to the stand-alone configuration. Increasing the feed concentration rate using the batch reverse osmosis process for the dairy wastewater treatment process can be an ideal solution from an economic point of view. Moreover, point (current density, feed concentration rate, total unit cost) = $$\left(328.9, 7, 14.37\right)$$ 328.9 , 7 , 14.37 can be considered as an optimal point for the economic performance of the studied wastewater treatment process.

BACKGROUNDPrinting and dyeing reverse osmosis concentrates (ROC) contain large amounts of salts and organic matter, which is a major environmental issue. The unique composition of such wastewater makes the use of traditional physicochemical techniques challenging.RESULTSIn this paper, titanium dioxide nanotube arrays/SnO2‐Sb2O3 (Ti‐NTA/SnO2‐Sb2O3) electrodes were prepared by anodizing–cathodizing and sol–gel method for the electrocatalytic degradation of printing and dyeing ROC. Organic matter removal under different situations was examined, and the best treatment parameters were identified.CONCLUSIONFollowing treatment, organic matter concentration dropped from 1600 to 50 mg L−1, or even less. The outstanding removal performance of the Ti‐NTA/SnO2‐Sb2O3 electrode was validated by full‐scan ultraviolet spectra, gas chromatography–mass spectrometry and three‐dimensional fluorescence. Evaluation of the dissolved heavy metals and halogenated degradation process byproducts revealed that the electrocatalytic membranes were environmentally safe. These findings highlight the enormous potential of electrocatalytic membranes for the treatment of high‐salt ROC when equipped with a Ti‐NTA/SnO2‐Sb2O3 electrode. © 2024 Society of Chemical Industry (SCI).
