The presented master thesis deals with polymeric membrane distillation. The task is a combination of mass and heat transfer that makes it a rather complicated problem. The goal of the thesis was to describe the mathematical model and perform experiments for validation. The described distillation unit uses polymeric hollow fibres to construct the condenser and the membrane module. The review of the heat and mass transfer is presented, and the membrane distillation is described. The mathematical model is derived and verified with measured data. The model gives a good prediction (up to 5%) for lower temperatures and for membrane modules with a lower number of fibres. An error above 10% is reported for higher temperatures and larger membrane modules. The author Jiří Hvožďa is a co-author of the Q1 publication “Fully Polymeric Distillation Unit Based on Polypropylene Hollow Fibers” that is directly related to the topic of this thesis and published data are also presented in the thesis. The author addressed the topic responsibly and independently. Within the work, he achieved all the set goals. Therefore, I recommend the submitted master’s thesis for defense.

Presented master thesis deals with membrane distillation. Especially from a mathematical modelling perspective. Membrane distillation is a complex phenomenon consisting of both heat and mass transfer. The author presents the necessary mathematical apparatus for membrane distillation and heat transfer methods.The basic principle of membrane distillation is sufficiently described for several different types of membrane distillation. The practical part of the work focuses on a particular type of membrane distillation (SGMD), with the membrane and condenser made in the form of polymeric hollow fibres. This type of SGMD unit was built and tested in the Heat Transfer and Fluid Flow Laboratory. The main result of the work is a mathematical model for SGMD, which allows to predict the final parameters of the tested membrane module based on the measured data from the initial part of the measurement. The predictions were validated by measurement. The objectives of the work were fulfilled. I recommend the thesis for defence.
