Abstract

The accelerated industrialization process dramatically increases the discharge of industrial wastewater, exacerbating the problems of water pollution and water shortage. Reverse osmosis (RO) has been widely used in the tertiary treatment of industrial wastewater to achieve the goals of water reuse or zero liquid discharge. However, the utilization of RO technology inevitably produces RO concentrate (ROC). Removing organic pollutants from ROC is of significant importance to meet the discharge standards or facilitate zero liquid discharge. This article reviews the research progresses in the treatment technologies removing organic pollutants in ROC from industrial wastewater sources. The water quality characteristics of ROC from industrial wastewater sources are firstly summarized. We then elaborate the physical and chemical processes commonly used for removing organic pollutants in ROC from industrial wastewater sources, e.g., electrochemical oxidation, ozonation, Fenton, and adsorption. This review also emphasizes the influencing factors affecting the removal of organic pollutants from ROC, particularly those highly related to the high salinity feature of ROC. In addition, the potential by-products produced during treatment of ROC are also discussed. This review provides a valuable reference for the process selection for removing organic pollutants in ROC produced from industrial wastewater.

期刊介绍： The Journal of Environmental Chemical Engineering (JECE) serves as a platform for the dissemination of original and innovative research focusing on the advancement of environmentally-friendly, sustainable technologies. JECE emphasizes the transition towards a carbon-neutral circular economy and a self-sufficient bio-based economy. Topics covered include soil, water, wastewater, and air decontamination; pollution monitoring, prevention, and control; advanced analytics, sensors, impact and risk assessment methodologies in environmental chemical engineering; resource recovery (water, nutrients, materials, energy); industrial ecology; valorization of waste streams; waste management (including e-waste); climate-water-energy-food nexus; novel materials for environmental, chemical, and energy applications; sustainability and environmental safety; water digitalization, water data science, and machine learning; process integration and intensification; recent developments in green chemistry for synthesis, catalysis, and energy; and original research on contaminants of emerging concern, persistent chemicals, and priority substances, including microplastics, nanoplastics, nanomaterials, micropollutants, antimicrobial resistance genes, and emerging pathogens (viruses, bacteria, parasites) of environmental significance.
