The potential of microfiltration and ultrafiltration processes as a methods of ayays of water treatment plants
Zelený, Zdeněk ; Biela,, Renata (referee) ; Kučera, Tomáš (advisor)
This bachelor´s thesis deals with the possibilities od using membrane filtration in water treatment process intensification. The introduction presents the formativ and development of these technologies, their progressive expansion and application. Then deals with specific properties and possibilities of using microfiltration and ultrafiltration membrane modules. Part of this work is the description of the materials used for making membranes, their advantages and disadvantages. Below are the possible approaches to setting and operation of filtration technology in drinking water supply for residents. Another important point of this thesis is the description of cleaning, maintenance and any repairs or expansion of membráně modules depending on the method of operation and the type of memebrane module. Another point mentioned in this study is the description of both methods of testing the integrity of membranes, direct and indirect. Testing of memebrane integrity is considered one of the most important advantages over alternative membrane filtration water treatment methods. The final part is devoted to recent findings from on going research a concrete example of the membrane device installed in the Czech Republic.

Measurements of permeability of dialysis membranes
Veselá, Martina ; Jiřík, Radovan (referee) ; Kolářová, Jana (advisor)
Familiarization with dialysis theoretical principles and determination of dialysis membrane permeability with the help of experimentally assembled apparatus is the aim of this bachelor thesis. The introduction part deals with basic knowledge concerning treatment with dialysis and its current quality. There continues a chapter stating an overview of dialysis membranes different types and main characteristics of individual materials, which the membranes were made of and which they are produced now. Theoretical preparation for the practical part of the thesis clarifies the basic notions, principals and processes connected with the mass transfer through dialysis membranes and dialysis. Further on, theoretical process is described and phrased how to determine dialysis membranes permeability in a laboratory scale in an experimental way. Two possible configurations of experimental apparatus are illustrated with block schemes working either in a non-stationary or a stationary regime of measurement. The basis to determine membrane permeability is sampling in specified time intervals from blood and dialyze side and spectrophotometric detection of samples concentration. The practical part itself is preceded with the process with collected samples analysis. Then, it is followed with relations derivation for mass transfer coefficient calculation. Concentration progress on blood and dialyze side with non-stationary way of measurement is modelled in Simulink programme. The practical part of the thesis uses the mentioned above theoretical knowledge and assumptions and it realises concrete measurements in non-stationary regime. Evaluating part of the thesis documents the obtained results and assesses them with the help of derived equations. The whole process of measurement including obtained results is evaluated and discussed in the final part.
