Design od laboratory apparatus for deep bed filtration research
Vejlupek, Petr ; Raček,, Jakub (referee) ; Figalla, Silvestr (advisor)
This Master’s thesis deals with the design of a rapid filtration laboratory apparatus. Basic design parameters were selected for the design of the apparatus, which were tested in the filtration process of the pilot unit. Based on the pilot test, the other design parameters were calculated. During the filtration process of the rapid filtration laboratory apparatus, turbidity removal was in the range of 95 to 100 %, reduction of absorbance A254 was in the range of 98.5–99.5 %, and reduction of chemical oxygen consumption by potassium permanganate was in the range of 96.1–99.3 %. At the end of the filtration cycle, the limits for drinking water given by Decree No. 371/2023 Coll. were achieved for pH values, iron concentrations, aluminum concentrations and chemical oxygen consumption by potassium permanganate. Glass beads with a grain size of 0.8–1.0 mm were the most suitable for the filtration run of the rapid filtration laboratory apparatus, which will be further used as a new exercise in the Water Technology laboratories. Ferric sulfate was proved to be the most suitable coagulant.

Water filtration and filter materials
Moravčíková, Světlana ; Talašová, Lucie (referee) ; Biela, Renata (advisor)
This bachelor thesis deals with water filtration. Primarily it describes slow sand filtration and rapid sand filtration. For these types of filtration, the filtration mechanisms, filtration cycles, filtration regeneration and filter layout are described in more detail. In case of the rapid filters, the most commonly used types of drainage systems are summarized. Further there is a brief introduction of diatomite filters and membrane processes used in water industry. The next chapter contains most commonly used filter materials along with their basic properties. Practical part of the thesis focuses on assessment of efficiency of selected filter materials in the removal of pollution.
