Of heat transfer fluid of heat systems
Ženožička, Filip ; Topič, Jan (referee) ; Počinková, Marcela (advisor)
The subject of this diploma thesis is the design of heating and hot water in the administrative building in Zlin on Jižní Svahy. The building has five floors above ground and one underground floor. There are designed two variants of heat source for heating and hot water (transfer sta-tions and gas boiler). Part A solves water quality in heating systems. Part B deals with design of the heating system, hot water heating, insurance and facility expansion, technical report and drawings heating in the building. The last part C is the experimental measurement of the quality of heating water in the CZT systems.

Hardness of Drinking Water
Kubešová, Kateřina ; Svoboda, Miroslav (referee) ; Kučera, Tomáš (advisor)
In the introductory part of this bachelor thesis deals with a research focusing on the hardness of water in general and as an indicator of quality of drinking water. Technical point of view is included and the role that the substances which cause hardening have on health is discussed. In the following part, there is an overview of water hardening and softening technologies. Finally, there are two consumables. In the first case, it is a hard-water consumer, in the second case there was a request for the distributed water to be harder.

Water quality analysis using colorimetry
Kovaldová, Eliška ; Zumberg, Inna (referee) ; Čmiel, Vratislav (advisor)
This bachelor's thesis deals with the analysis of water quality using colorimetry. Part of the work is an introduction to the physical and chemical parameters of water, as well as optical methods, which include photometry, spectrophotometry and colorimetry, and an introduction to regression analysis. These methods and analysis are followed by a practical part by measuring pH, nitrate and water hardness using a spectrophotometer and an AS7262 visible light sensor with a SparkFun development board. At the end of the work there is a comparison of absorption spectra, calibration curves and linear regression parameters of both methods.

Water Treatment Efficiency Using Membrane Filtration
Zelinová, Kristína ; Kolesíková, Lucie (referee) ; Kučera, Tomáš (advisor)
In the first part of this thesis, current requirements for drinking water according to the legislation valid in the territory of Czech Republic and Slovak Republic are summarized. Also the changes that will come with implementation of the directive 2020/2184 of the European parliament are mentioned. Following those future changes, the importance of new technologies for water treatment comes to light. Among those technologies belong membrane processes. The rest of the thesis is dedicated to them. At first, current knowledge of their operation principles and categories, to which they can be divided into are reviewed. Then, the processes related to their maintenance are approached. Mentioned are few specific water treatment plants in Czechia and Slovakia, where membrane processes were already applied. The scientific part of this thesis consists of series of tests, executed on an ultrafiltration unit, in laboratory conditions. Including optimalization of the filtration process, as well as observation of the pollutants removal efficiency from surface water. Towards the end of the thesis, recorded values are evaluated.

The influence of the surrounding landscape , fishery management , external and internal factors on water quality in ponds
Janáček, Štěpán ; Vach, Marek (advisor)
The thesis deals with the influences that affect water quality in the ponds . It focuses on selected factors which define water quality . These include e.g. the amount of dissolved oxygen in the water , ammonia, etc. To determine the change in water quality in a fish breeding tank, measured quality of water at the inlet of the tank and at its drain. I enter into the analysis and facts about the amount of fish stocking in ponds , basin shape , location of the pond in the countryside , farming in the watershed .
