Drinking water is crucial for human existence and other lifeforms. Due to many factors, including anthropogenic, its sources are becoming increasingly strained and exhausted, with many parts of the world facing the consequences that are worsening human living conditions. Among the solutions for this problem is seawater desalination, for which many technological processes exist, one of which being membrane distillation. The most important part of the process is the membrane, which is prone to accumulation of materials on its surface. This hinders the process and the focus of this thesis was to check, whether it is possible to alleviate the effects of material accumulation with the use of cavitation. We proved it possible and that improving the process is feasible even when cleaning highly saline water, with the correct implementation of cavitation being crucial. The research included design and construction of a laboratory measurement station, which enabled measurements of distillate flux across the membrane with and without the use of cavitation. Special attention was devoted for the choosing of an appropriate material to be used in the condensate-draining part of the station.
