Exploration and case analysis of treatment processes and reuse pathways for industrial brine wastewater in China

Treatment of industrial brine wastewater, which is characterized by multiple sources and complex water quality, poses significant challenges. Brine separation technology can effectively address the difficulties in brine wastewater treatment while facilitating water reuse and the separation and resource utilization of crystalline salts, thus providing important development opportunities in wastewater treatment. This study comprehensively and systematically reviews and summarizes the treatment processes and reuse pathways of brine wastewater based on practical investigations in different industries, providing technical guidance and experience for relevant brine wastewater treatment and reuse cases. This study is of great significance for promoting the standardization and management of wastewater treatment and reuse worldwide. Finally, suggestions and prospects for further promoting the standardized management of brine wastewater reuse are proposed.
