Sensors for decentralized system of water purification
Plotěný, Miroslav ; Mácha, Tomáš (referee) ; Martinásek, Zdeněk (advisor)
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.

The amount of waste from wastewater treatment process
Žíla, Radim ; Macsek, Tomáš (referee) ; Hluštík, Petr (advisor)
This Bachelor's Thesis is focused on the amount of waste produced by the sewage treatment plants for the amount up to 2.000 equivalent inhabitants with the gravitational inflow. There are all the types of individual sewage treatment plants of the size up to 2.000 equivalent inhabitants listed in the first section of the theoretical part and the second section of the theoretical part deals with the thorough analysis of all the objects within the sewage treatment plant, their draft specifications and the description of the waste handeling. The practical part of this Bachelor's Thesis deals with the evaluation of the production of waste for the amount up to 2.000 equivalent inhabitants in individual municipalities within the South Moravian region. More specifically it describes the waste of screenings, sand, insoluble substances and sludge on one equivalent inhabitant and its subsequent comparison with the regulation according to ČSN. The evaluation compares all the municipalities among each other and their production of waste is also compared to ČSN.

The waste management of the constructed treatment wetlands
Mrvová, Michaela ; Hyánková, Eva (referee) ; Kriška-Dunajský, Michal (advisor)
The thesis is focused on the sludge management at root sewage treatment plants with focus on volum eis highest – sludge manahement. Sludge dewatering using sludge dryiing bed is still condemned designers mainly due to their lack of experience, while at the same time enforcing technologically complex solutions. Therefore, the thesis focuses on the break down balance hydrological equation sludge drying bed, which includes all parameters affecting water balance system. The result is a proposal not only design, but in particular a description of input data and the governing equations in software Reed-Bed, which is calibrated own operational results obtainde for the two sewage treatment plants (village Dražovice and Kotenčice). Reed-Bed software will perform sevetal functions: setting the ground area of sludge bed, investment costs required for the implementation of sludge bed, return on investment, the determination of moisture contene of sludge in the sludge bed and maximum lenght of the dewatering period with regard to wetland vegetation. The second largest item within sludge system creates biomass wetland plants, so work deals with possibilities biomass processing plant at the end of the growing season. Technological processing of biomass was tested on common reed, final product pellets for heating.

The study village sewer system Prasklice
Gembalová, Barbora ; Mlčoch, Ondřej (referee) ; Hluštík, Petr (advisor)
The diploma thesis deals with the assessment of the existing condition of the sewerage system and the proposal of measures for disposal of sewage in the village Prasklice. Submits a proposal for three options for improving the condition of the drainage and resolve the disposal of sewage. Option 1. consists in the design of new separate system and reconstruction of existing stormwater, the original combined system. To this option, including the proposal of the central sewage treatment plant. Option 2. includes the design of the pumping station for the diversion of sewage effluent to wastewater treatment plant that is proposed in the next village Pačlavice. Option 3. describes the reconstruction of the existing combined system and design of the central sewage treatment plant. The individual proposed technological solutions to the drainage and treatment of waste, is created overview of the economic performance. The object is to determine what the least economically demanding variant and show how subsidies can be used. Economically least demanding option was evaluated option 3. From an operational point of view it is most advantageous to variant 1., which will prevent future operating costs. The diploma thesis brings the village Prasklice a convenient solution for sewerage and sewage disposal in the village.

Study of wastewater management solutions for the village of Lhotka
Vojvodík, David ; Pumprlová Němcová, Miroslava (referee) ; Kriška-Dunajský, Michal (advisor)
The bachelor's thesis is focused on the processing and comparison of possible variants of sewerage in the Lhotka locality. It presents a proposal for three variants for improving the state of wastewater management in Lhotka. Option 1 envisages the design of a mechanicalbiological WWTP for sewage, with the proviso that the existing unified sewer will be used for rainwater drainage. Option 2 includes the design of an extensive type of wastewater treatment plant and the completion of the existing integrated sewerage system. The last variant 3 includes the pumping of wastewater by discharge to the Malenovice WWTP. The solution is in accordance with PRVKZK. An overview of economic demands is created for individual technological solutions. The aim is to determine the most suitable solution from an economic and technical point of view.

Failure rate wastewater treatment plants
Boryśová, Michaela ; Vlčková, Veronika (referee) ; Hluštík, Petr (advisor)
This thesis deals with the sludge management in wastewater treatment plants. It provides a basic overview of methods for modifying risk material in sludge ending. The main goal of this work is to create a fault trees based on faults which occurred in the sludge management facilities. Furthermore, it was created frequency of failures assessment of the objects on wastewater treatment plant in Hodonín. Provided information were obtained during excursions of WWTP Hodonín and Zbýšov.

Upgrading of wastewater treatment plant by means of MBR technology.
Spratková, Aneta ; Rusník,, Igor (referee) ; Hlavínek, Petr (advisor)
This diploma thesis is focused on the topic of membrane technologies used in wastewater treatment. The research part of the thesis deals with membrane separation of activated sludge, and the focus is on the submerged membrane modules. The thesis contains basic principles of MBR systems, an overview of used membrane modules, modes of operation, advantages and disadvantages of using this process. The practical part of the thesis proposes the intensification of WWTP Perná with using MBR technology. This part includes the technical-economic assessment of the activation WWTP with the third stage of treatment and activation WWTP with MBR.

The study alternatives village up to 2000 PE
Krupicová, Simona ; Balas, Jan (referee) ; Hluštík, Petr (advisor)
The diploma thesis deals with the design of variants of sewerage and wastewater disposal in the selected municipality. Solved area for this work is the village Rovečné with the local part of Malé Tresné. The aim of this work is to propose a suitable variant and to assess it from the economic point of view with regard to grant titles. The author deals with the selection of a suitable method of sewerage of the area of interest and subsequent waste water disposal, based on the relevant standards and related regulations. The proposed options are then assessed from an economic point of view and a suitable solution option is recommended.
