Desalination and treatment of wastewater has become critical for Asia regions with water scarcity. In this work, the concept of thin-film distillation equipped with a porous condenser (FDPC) was considered for its implementation in a tropical climate of Vietnam. It was found that samples with a concentration of biocide of 0.5 wt.% possessed lower biofouling, in contrast to the neat membranes. The FD-PC module was developed and water desalination experiments were conducted in Russia and Vietnam. The experiments showed high reproducibility of the results; in particular, the evaporation rate was (4.9/3.0) kg/mh in Russia and (4.1/2.0) kg/mh in Vietnam. In addition, as part of this work, the optimal configuration of the installation was calculated using solar collectors as the main energy source. The calculation showed high energy efficiency: specific energy consumption 0.1-0.5 kWh/m.
海水淡化和废水处理对于水资源匮乏的亚洲地区而言至关重要。在本研究中，考虑了配备多孔冷凝器的薄膜蒸馏（FDPC）概念，以便在越南的热带气候中实施。结果发现，与纯膜相比，杀菌剂浓度为0.5 wt.% 的样品具有较低的生物污染。开发了FD-PC模块，并在俄罗斯和越南进行了海水淡化实验。实验结果显示出高度的可重复性；特别是，俄罗斯的蒸发速率为(4.9/3.0) kg/mh，越南为(4.1/2.0) kg/mh。此外，作为本研究的一部分，以太阳能集热器作为主要能源，计算了装置的最佳配置。计算结果表明能源效率很高：单位能耗为0.1-0.5 kWh/m。
