The use of alternative coagulants in water treatment
Hofmanová, Lucie ; Zelený, Zdeněk (referee) ; Kučera, Tomáš (advisor)
This bachelor's thesis deals with the use of alternative coagulants in water treatment. The first theoretical part mentions types of water treatment for the individual categories of raw water, related laws and ordinances. After that thesis describes the principle, mechanisms of coagulation and factors influencing the process. It analyses the jar test procedure performed within the experimental part of the bachelor's thesis. One chapter deals with polymers and metal coagulants based on aluminium and iron commonly used in water treatment. The chapter includes more detailed description of natural polymers moringa oleifera and chitosan. These two coagulating agents and aluminium sulfate were used in the second experimental part of the bachelor's thesis. Several sets of the jar test were performed in order to investigate the efficiency of chosen coagulants on the removal of turbidity from water. The thesis concludes with a comparison and evaluation of the results. Photos taken during the jar test can also be found at the end of the bachelor's thesis.

Reconstruction of Water Treatment Plant
Skříček, Jan ; Roh, Robert (referee) ; Kučera, Tomáš (advisor)
The aim of the master thesis was to propose the reconstruction of the water treatment plant. I chose the water treatment plant in Čebín, which I have already describe with in the bachelor thesis. The water treatment plant has problems with increased iron, manganese and ammonium salts. In the first part I devoted myself to the current condition of the water treatment plant and the possibilities of removing the elements from the water. In the next chapter I compiled the equipment of the technological line. To remove iron and manganese, I suggested aeration using an injector, and for the removal of ammonium salts, potassium permanganate is used, which is used to regenerate the filters. A pair of pressure filters helps remove iron and manganese. In the last part of the thesis I described and evaluated the original condition of the water treatment plant. To evaluate the technical condition, I used the TEA Water web application.

The Analysis of Water Distribution Network of Vysoká nad Labem Municipality
Bakrlík, Marek ; Netušil, Lukáš (referee) ; Kučera, Tomáš (advisor)
The goal of my bachelor’s thesis is to assess the current supply system of drinking water in the village Vysoká nad Labem. The growth of the village has been the cause of the increasing consumption of drinking water. Due to the increase in water withdrawals the pressure conditions in the supply network has been also changed and has been struggling with the legal limits. Particularly the paper will focus on an evaluation of the pressure ratios at the highest point of the village followed by the design of a possible division to the pressure zones due to the potential supply by several sources.

Multifuntional house
Kučera, Tomáš ; Burianová, Lenka (referee) ; Smolka, Radim (advisor)
This diploma thesis focuses on the design of new multifunctional building in Frydek-Mistek. Project and attachments are processed according to the current laws, regulations and standards. Multifunctional House is located on parcels 3364/190 and 3503/1, in the cadastral Místek. The house has four floors and reside in 3 commercial units and in the last two floors 5 residential units. The other two dimensions of the house are 21,15x13,15m. Roofing the house is solved by a flat roof. The building is brick ceramic blocks Porotherm. Ceilings are made up of reinforced concrete panels. The construction is based on flat base structures that form the plain concrete C20 / 25 and the supporting concrete slab thickness of 150 mm is reinforced curry networks 100/100/6.

The effect of reduction core on the water impermeability and frost resistance of brick body
Kučera, Tomáš ; Stančík,, Hynek (referee) ; Sokolář, Radomír (advisor)
The bachelor thesis reviews effect of reduction core on the basic physical and mechanical properties of fired roof tiles. Theoretical part summarizes the knowledge about the reduction cores effect on the properties of the brick body and describes the basic rules for the successful reduction core elimination during firing of the brick body. In the experimental part are mainly compared properties of porosity, bend strength, impermeability and frost resistance of laboratory prepared samples and those are compared based on differently developed reduction core due to different firing.
