Studie úpravny vody z povrchového zdroje / Study of water treatment plant from surface source

Inwald, Petr January 2021 (has links)
The first part of the thesis deals with water sources and methods of drinkable water treatment. This section describes the technologies used for two-stage water treatment from a surface source. The second part deals with study of the new drinking water treatment plant from a surface source for Adamov town. The work documents the current state of the existing water treatment plant and describes used technology with a design flow Q = 30 l s-1. In the next part of thesis is design of two variations of new technological line with a design flow Q = 10 l s-1. The first variation is one-stage water treatment with pressure filters as the main separation stage. Two-stage water treatment is designed for the second variation, in which the first stage of separation are clarifiers and the second stage are pressure filters. Thesis includes drawing documentation of designed pressure filters and clarifiers, technological and height scheme of both variations.

Stanovení vybraných "Musk" sloučenin v biotických vzorcích / Determination of selected musk compounds in biotic samples

Blahová, Eliška January 2008 (has links)
Musk compounds (MUSK) or synthetic fragrances are organic substances commonly used as fragrant constituents of detergents, soaps, cosmetics, personal care products, industrial and in-house cleaning agents, industrial plasticizers, chewing tobacco and fresheners. The big attention is pushed ahead studying these compounds, their fate in different parts of ecosystems and studying their characteristics at present, because musks infiltrate many environmental components, particularly aquatic and marine ecosystems, through their large application and their ability to be perzistant. This diploma thesis was focused on four synthetic “classical” fragrances used over the world. The aim of this study was to perform a method optimisation for the determination of selected fragrances in biotic matrix. There was made an evalution of ability of selected water treatment plant to clear away musks from water, these results were used for evaluating contamination measurement of aquatic ecosystem. The identification and quantification of analytes was carried out by high resolution gas chromatography - mass spectrometry (HRGC/MS).

Sledování koncentrací organických látek podél technologické linky úpravny vody ve Štítarech / Monitoring of concentration of organic matter along the technological line of drinking water treatment plant in Štítary

Hubená, Renáta January 2010 (has links)
General part of thesis deal with information on technology of water treatment and its changes at drinking water treatment plant Štítary. In experimental part of the document are presented treated data on monitoring of concentration of organic matter along the technological line of reconstructed drinking water treatment plant in Štítary for period since 2009 to 2010.

Senzory pro decentralizovaný systém čištění odpadních vod / Sensors for decentralized system of water purification

Plotěný, Miroslav January 2009 (has links)
Main task of the Master Thesis is to study and propose appropriate sensors that can monitor standard operations of small waste treatment plant. This small plants may replace one big central waste water treatment plant, minimizing interference with the human factor and thus reducing the cost of its operation. Master Thesis deals with the sensors for level measurement, air flow, identifying the operator and others. The most important parameter is the quality of drainage water, which can be derived from the amount of ammoniacal nitrogen. This work discusses the possibility of continuous measurements of ammoniacal nitrogen in water and try to select the optimum solution. At the end of the work is carried out experimental measurements are selected ammonia probe to verify the practical features.

Zdravotně technické instalace ubytovacích zařízení / Plumbing Systems for Accommodation Facilities

Možná, Pavlína January 2013 (has links)
Master’s thesis "Plumbing systems for accommodation facilities" is processed in the form of project documentation plumbing according to applicable regulations. Designed building has five floors, basement. The ground floor restaurant and relaxing part of the hotel, in the remaining floors are guest rooms with 75 beds. One room is completely wheelchair. The building is located outside urban areas without connection to public utilities. The work focuses on the design of plumbing hotel and presents two variants of the possible solutions for waste water from the building. Building water supply is secured from drilled wells and the proposed pumping equipment.

Energetické náročnosti kanalizačních sítí / Energy Performance of sewerage networks

Žďára, Jan January 2013 (has links)
First section of this master thesis is background research of energy demand of sewer systems. Intrudoctory chapter explains basic concepts. Second chapter is dealing with Czech and European legislation concerning energy consumption of water service. Third chapter describes energy demand of sewer systems. In this chapter there are described conventional gravity, vakuum and pressure sewer systems and components with major power consumption. Fourth chapter describes actual state of energy demand of WWTP and possible ways of improving power consumption of WWTP. Second section is a review of energy consumtion of vacuum systems of five different municipalities including one WWTP. Measured and evaluated outputs were used to create energy audit methodology for sewer systems.

Poruchové stavy úpraven vody / Water Treatment Plants and their Failure Modes

Baranová, Zuzana January 2013 (has links)
The aim of this thesis was to conduct a survey in selected water treatment plants to identify possible faults with which treatment providers may encounter. Within the thesis has been visited these treatments: ÚV Troubky, ÚV Hosov, ÚV Příkazy, ÚV Černovír. Further was performed evaluation of the collected information, specification and frequency disturbances occurring on those premises.

Návrh čistírny odpadních vod v lokalitě s extrémními požadavky na jakost vyčištěných vod. / Design of WWTP at locality with extreme demands on quality of treated wastewater

Krupica, Radek January 2013 (has links)
This diploma thesis deals with the wastewater treatment technologies by means of which high quality of the treated wastewater is attained, especially with regard to removing nutrients. The introduction of the thesis contains, among others, descriptions of the reserves in the Czech Republic where it is extremely important to insist on the highest quality of the discharged wastewaters. Then follows a summary of the quality requirements on the discharged wastewaters as stipulated in the legislation. Furthermore, I analyse the impact of the nutrients – nitrogen and phosphorus – on the environment and the principles of their removal from the wastewaters. In the next section I concentrate on the technological processes by means of which the required quality of the wastewater is achieved. The conclusion includes a list of technologies used as the tertiary wastewater treatments with emphasis on membrane technologies. The second part of my thesis is a study of a project of a wastewater treatment plant (WWTP) with membrane technology for the villages of Sloup and Šošůvka located within the protected landscape area of Moravian Karst.
