Abstract Robust ceramic membranes could enable membrane distillation processes for the treatment of aggressive solutions and help to facilitate ZLD. In order to adapt ceramic membranes for MD processes insights into the impact of membrane properties (such as thermal conductivity and layer design) on process performance have to be gained. Therefore, conventional and unconventional asymmetrically structured ceramic membranes with different properties were manufactures, modified, characterized and tested in DCMD and VMD. For instance, a maximum permeate flux of 25 kg/(m2 h) at excellent rejections (>99.9%) was determined. In VMD, it was found that the mass transfer depends almost entirely on the support properties such as thickness and pore size whereas in DCMD the membrane layer properties significantly affect the performance.

MD 工艺中的疏水陶瓷膜——材料选择和层特性的影响

摘要 坚固的陶瓷膜可以使膜蒸馏过程用于处理腐蚀性溶液并有助于促进 ZLD。为了使陶瓷膜适用于 MD 工艺，必须深入了解膜特性（例如导热性和层设计）对工艺性能的影响。因此，在DCMD和VMD中制造、修改、表征和测试具有不同性质的常规和非常规非对称结构陶瓷膜。例如，在极好的拒绝率 (>99.9%) 下，测得的最大渗透通量为 25 kg/(m2 h)。在 VMD 中，发现传质几乎完全取决于载体特性，例如厚度和孔径，而在 DCMD 中，膜层特性显着影响性能。
