This master thesis is focused on groundwater remediation of chlorinated ethylenes and methanes in the area of chemical factory Spolchemie in the Czech Republic, Ústí nad Labem city. For these purposes nano zero valent iron particles were used. For the remediation two separate applications of different types of particles together in suspension with tracer (lithium chloride), were carried out. The results from the first application were evaluated by the supervisor of this thesis and are briefly summarized and discussed together with the second application which was evaluated by the author of this thesis. Second application of particles was carried out in October 2015 and observed for 424 days. Observation consisted of monitoring of groundwater level, physical-chemical parameters and collection of water samples for the analysis of concentrations of chlorinated hydrocarbons, their degradation products and several chosen ions. Nanoiron particles had the assumed effect onto the physical-chemical parameters and reduction of contamination. The application of tracer had proven the expected groundwater flow and made a possibility to distinguish between the process of reductive dehalogenation and dilution caused by the injected water, the dilution did not exceeded 5 % in most monitored points. Other...

This diploma thesis is aimed at the evaluation of water treatment technology in Písty waterworks which treats raw water with high concentration of iron and manganese. The most common method of iron and manganese removal from raw water is based on oxidation to insoluble hydrated oxides followed by separation of formed aggregates. The plant technology consists of aeration, oxidation agent KMnO4 dosing and mixing, sedimentation, filtration and hygienic protection. Chemical analysis of treated water, evaluation of the aeration efficiency of iron and manganese oxidation, evaluation of the separation efficiency of the sedimentation tank and filters, assessment of distribution of iron and manganese in the filter, assessment of dirt holding capacity and optimization of KMnO4 dose were determined. Raw water pH fluctuated around 7,3 during measurements, whereas iron and manganese concentrations in raw water were 6,00 and 0,82 mg.l-1 , respectively. Oxidation of 97,2 % of dissolved iron and of 14,3 % of dissolved manganese was achieved after the aeration. The separation efficiency of the sedimentation tank was 82,9 % for iron and 46,5 % for manganese, however the separation efficiency of the second half of the sedimentation tank was low. Thus, the perforated baffles in the second half of the sedimentation...

The topic to Diploma Thesis is design of Biological Wastewater Treatment for 450 PE in Hvozd Commune (Region Olomoucký). First part is dedicated to description of multiple possible variants of design. In the following part is more detailed described chosen technology. Except from description of technology are also shown parameters calculations proposal. Some of the main reasons for preference of Biological Wastewater Treatment are low maintenance requirements, independence of energy supply or possibility of future sludge treatment. Foundational materials for the design were first, Local Zoning Plan which describes current and future drainage and wastewater disposal situation. Second, study aims at parameters calculations of French system. Project documentation is part and parcel of this thesis. Documentation will also be a basis for planning building permission.

The work deals with the practical design of constructed treatment wetlands for Kurovice. The proposed treatment wetlands have an estimated size of 300 EO. For the design were used the most modern technologies available. The whole diploma thesis is divided into a theoretical search and practical design. At the beginning, there is a description of the target area and is followed by the proposal of individual facilities. In the conclusion of the theoretical part, the efficiency of the constructed treatment wetlands is compared with the legislation. The practical part consists of the design of constructed treatment wetlands. The design was focused on the technologies used and the spatial arrangement of individual buildings based on the atypical shape of the land. The whole proposal is made to such an extent that it can serve for subsequent use as project documentation for land management and building permits.

The aim of my master's project is to design a new building of kindergarden with nearly zero energy consumption. The project consists of three main parts. The first part is to create project documentation. The building is designed regarding to architectural expression. The kindergarden is split into two departments each for twenty children. It is single storey building with saddle roof. It is based on concrete foundation and under them there is foam glass. External walls are made of sand-lime blocks which are insulated with a contact thermal insulation system. The second part is to assess the energy performance of the building and usage of energy from renewable sources. The building uses ground source heat pump as a heating, air is provided by mechanical ventilation with heat recovery and eleckricity is partly provided by a photovoltaic system. The last part of master's project evaluates the building by the method of multi–criteria analysis. For this evaluation I used national method SBToolCZ.

The paper describes the development of water quality based on selected pollution indicators in the source catchments of the Berounka River (Mže catchment, Radbuza catchment, Úhlava catchment and Úslava catchment of selected sub-catchments) on profiles located above the water quality monitoring profile Bukovec on the Berounka River from 1981 to 2019. Furthermore, the flow dependence during the monitored period and from it the predominant type of pollution in the given catchment is determined on the basis of the course of regression curves and the value of the coefficient of determination R2 . Based on the average annual concentrations, the evolution of the given pollution indicators on selected profiles is described for the longest possible monitoring period for which water quality data are available. Their evolution within a calendar year can be determined when the flow rate is exceeded. By means of mass transport, the actual amount of pollutants can be determined on the basis of the concentration and the flow rate. The specific mass transport then express the intensity of removal from an area of 1 km2 for a given time interval, which has been chosen here as well as the pollutant loads for one year. The observed results are then converted into graphical output. Based on the data, it is possible to...

This thesis deals with the description of the pressure sewerage systems. Primarily focuses on the assessment of operation of the pressure sewerage system of the municipality Štěpánovice, where he was evaluated on the network pressure, flow of waste water, waste water quality and system silure rate.

Title: Effect of cold water immersion on intermittent isometric forearm flexor contractions to failure in rock climbers Objectives: The aim of this study was to determine the effect of cold water immersion on intermittent isometric forearm flexor contraction to failure in rock climbers. Methods: Thirty-two climbers (15 male and 17 female) completed three intermittent trials to failure, on a climbing-specific handgrip dynamometer, on three separate visits to the laboratory. For each visit a different recovery strategy was employed: passive recovery (PAS), cold water immersion at 8 řC (CWI 8) or 15 řC (CWI 15). The force time integral (FTI - time of contraction multiplied by the force of contraction) was determined to assess intermittent performance. The tissue saturation index (TSI) and total haemoglobin (tHb) during isometric contractions from near-infrared spectroscopy (NIRS) were determined to assess hemodynamic changes. Differences between repeated trials and three recovery protocols, derived parameters NIRS, were assessed using repeated measures ANOVA with Bonferroni corrections. Results: There was no significant difference between conditions after trial one. In response to the PAS recovery condition there was a 10% and 22% decrease in FTI in the second and third trials, respectively. The PAS...

This diploma thesis deals with rainwater harvesting system in the company premises and the design of plumbing system in the newly built training center and storage hall. The new standard EN 16941-1 is described in the teoretical part. This standard deals with the use of rainwater. The experimental part solves the measurement of the non-potable water in this area. In the practical part, the acquired information is applied to the newly built object in the company premises. A project is created in the form of a technical report and drawing documentation for the use of rainwater and plumbing system.
