摘要：

Membrane distillation (MD) process is capable of utilizing ultra-low temperature heat (−2, 4.1% higher than VMD-FPC in a 10-h operation with 22.8 MJ m−2 of solar energy. Considering heat recovery for both systems, an even bigger difference in production, up to 11.7% could be observed. Such performance elevation is attributed to the localized heating at membrane surface and more efficient conversion of solar energy to evaporation heat. Results also indicated that utilizing photothermal membranes can indeed relieve the issue of temperature polarization. However, such phenomenon cannot be entirely eliminated. © 2021 Elsevier Ltd
