Design of algorithms for a continuous steam quality measurement system
Hanák, Tomáš ; Tofel, Pavel (referee) ; Holcman, Vladimír (advisor)
This bachelor thesis deals with proposal of algorithm for continuous system of sterilizated steam. At the beginning we deal with the process of sterilization and its methods. Later on we talk over about the saturated steam and parameters of saturated steam. At the end of the bachelors thesis we discuss about current measurement of sterilization steam quality. Then, the procedure of simultaneous measurement of sterilization steam quality is described here. The last part is the evaluation of measured data and presentation of their results.

Comparison of antimicrobial effect of emulsions for cleaning and dissinfection
Chrápavá, Edita ; Dzurická, Lucia (referee) ; Márová, Ivana (advisor)
Currently, hand disinfectants and other disinfectants are in high demand. Due to the pandemic and the spread of Covid-19, they are used by society daily. The reason for their use is not only to prevent the spread of bacteria and other microorganisms from the hands to another part of the body or objects, but also to prevent the spread of the disease. The subject of the bachelor thesis is the control of antimicrobial effects of several commonly available disinfectants using broth and agar dilution methods. From the measured data, the absorbance was processed and subsequently viability of the culture.

Appliance For Automatic Disinfection Of Interiors
Korotynskiy, Alexander
The work mainly deals with existing solutions for interior disinfection, their analysis andselection of a suitable situation. This article also deals with the appropriate selection of componentsfor the implementation of mobile disinfection appliance. Subsequently, an analysis of the electricalconnection of the driver for the DC motor is performed. Part of the article is also acquaintance withthe programming language Rust, in which the firmware for the DC motor driver is created.

Application of cavitation in industrial processes
Hamar, Oliver ; Tancjurová, Jana (referee) ; Rudolf, Pavel (advisor)
The bachelor thesis deals with the research of the application potential of cavitation technologies in various industries. Thanks to its properties, cavitation seems to be a promising tool for streamlining a large number of industrial processes in several aspects. The first part deals with the theoretical description of the cavitation phenomenon, its negatives and methods of their detection. The second part focuses on the analysis of possible usage areas of cavitation technologies and the ways of generating the cavitation, focusing on current research and findings in the area of hydrodynamic cavitation application.

Kinetics of electrophotocatalytic water disinfection
Štefancová, Eva ; Zita, Jiří (referee) ; Veselá, Mária (advisor)
In this work, electrophotocatalytic disinfection on selected microorganisms was verified. The electrophotocatalytic system allows the application of electrical bias to the photoanode coated with a titanium dioxide layer. The disinfecting effect was observed on E.coli and C.glabrata in aqueous solution. The effect of radiation intensity on electrophotocatalysis and selected optimal conditions for further experiments was observed in the E. coli organism. Photocatalytic disinfection was carried out under suitable conditions on C.glabrata yeast and the effect of sodium sulfate electrolyte on electrophotocatalytic disinfection was observed in this case.

Industrial application of TS displays
Chytil, Lukáš ; Zemánek, Miroslav (referee) ; Boušek, Jaroslav (advisor)
This master thesis describes the design of control unit, which has the task to operate industrial facilities for disinfection of swimming pools or living rooms. The designed control unit is trying to regulate power and flow rate, which is controlled by electronic valve with a flowmetr. The whole design is aimed at minimizing operating costs (mainly consumed liquid oxygen). Interaction with the operator is ensured by the HMI display. There is also an effort to highlight the importance of HMI applications in the industry.

Influence of disinfectants on the content of lactic acid in the production of refined sugar
Novotná, Hedvika ; Skoumalová, Petra (referee) ; Horák, Radek (advisor)
The diploma thesis compares the effectiveness of disinfectants on the content of the lactic acid. The disinfectants used for the experimental part are formalin and BetaStab®. The content of glucose and lactic acid was observed and compared after processing conventional beet and bio-beet. Based on the analysis of the measured data, it was found that the highest disinfecting effect on the lactic acid content had formalin, the avearge lactic acid value was 275 mg/l. In experiment with BetaStab® disinfection the average value of the lactic acid was 350 mg/l. When the beet was processed without the use of disinfection, this average lactic acid was 371 mg/l and in the untreated treatment of the bio-beet, the lactic acid content was 467 mg/l. The glucose content of formalin disinfection diffusion juice reached an average of 573 mg/l. When BetaStab® disinfection was applied, the average glucose content was 348 mg/l and a similar value was measured for the bio-beet treatment (328 mg/l). The highest glucose content had untreated conventional beet, where an average value of 690 mg/l was reached.
