膜蒸馏用膜材料与高效膜蒸馏反应器

传统疏水膜材料抗污染与耐润湿功能偏弱，极易被污染，导致膜通量下降或膜蒸馏完全失效，针对目前存在的瓶颈，研发以新型超疏水复合膜为技术核心，将非溶剂致相转化膜制备工艺与膜分离表面后处理技术相结合，开发面向膜蒸馏过程的机械强度高、膜通量大、耐润湿、抗污染型超疏水复合膜，完成高浓盐水的进一步提浓，详见论文及专利。Traditional hydrophobic membrane materials suffer from poor antifouling and wetting resistance, and are highly susceptible to fouling, which leads to reduced membrane flux or complete failure of membrane distillation. To address these existing technical bottlenecks, we developed novel superhydrophobic composite membranes as the core technology, by combining the non-solvent induced phase separation (NIPS) membrane fabrication process with post-surface treatment technologies for membrane separation. The resulting superhydrophobic composite membranes feature high mechanical strength, high membrane flux, excellent wetting resistance and superior antifouling performance, tailored for membrane distillation processes, enabling further concentration of high-concentration saline solutions. Detailed information can be found in the related papers and patents.
