Abstract

The expansion of industrial activities has generated a substantial amount of wastewater containing high concentrations of hazardous substances, presenting considerable environmental and health hazards. Membrane technologies, including nanofiltration (NF) and reverse osmosis (RO), have become integral to the treatment and reuse of industrial wastewater, offering high separation efficiency, low energy consumption, and environmental sustainability. This paper provides a comprehensive review of the current state, challenges, and potential solutions associated with NF/RO treatment in industrial wastewater management. It offers an overview of the characteristics of various industrial wastewaters and relevant treatment advancements. This paper proposes the challenges and corresponding solutions in treating industrial wastewater, specifically focusing on strategies for mitigating membrane fouling through pretreatment, membrane modification, and effective cleaning techniques. Additionally, this study provides approaches to minimize membrane oxidation and manage NF/RO concentrates, while considering prospects such as zero liquid discharge (ZLD) and resource recovery from concentrates. This work suggests future research directions and offers theoretical perspectives for advancing NF and RO processes in industrial wastewater treatment.

期刊介绍： Separation and Purification Technology is a premier journal committed to sharing innovative methods for separation and purification in chemical and environmental engineering, encompassing both homogeneous solutions and heterogeneous mixtures. Our scope includes the separation and/or purification of liquids, vapors, and gases, as well as carbon capture and separation techniques. However, it's important to note that methods solely intended for analytical purposes are not within the scope of the journal. Additionally, disciplines such as soil science, polymer science, and metallurgy fall outside the purview of Separation and Purification Technology. Join us in advancing the field of separation and purification methods for sustainable solutions in chemical and environmental engineering.
