Abstract

The membrane separation process in high-salinity wastewater treatment faces challenges such as high energy consumption, severe scaling, and increased operational costs. To address these issues, this study investigates the impacts of different operating conditions on system energy consumption and separation efficiency through three approaches: membrane material selection, process parameter optimization, and energy recovery strategies.
Results demonstrate that optimizing membrane pressure difference, flow rate, and pretreatment protocols can effectively reduce energy consumption while maintaining stable effluent quality. These optimization methods have proven feasible through experimental validation and simulation analysis, providing a reference for efficient operation of membrane separation processes in high-salinity wastewater treatment.
