Porous membrane distillation technology has attracted considerable attention due to its high efficiency in removing dissolved substances from high-salinity wastewater. However, during practical application, membrane fouling seriously impairs the treatment performance and stability of the technology. To enhance the anti-fouling capability of membranes, this paper explores several fouling mitigation strategies, including membrane surface modification, addition of cleaning agents, and optimization of operating conditions. By optimizing these strategies, the degree of fouling on the membrane surface can be significantly reduced, thereby improving the treatment efficiency and operation cycle of the membrane distillation system. The effectiveness of these strategies provides new insights for high-salinity wastewater treatment, and is of great significance especially in reducing energy consumption and extending membrane lifespan.
