Study of sewerage and wastewater disposal
Dvorský, Petr ; Úterský, Michal (referee) ; Hluštík, Petr (advisor)
This thesis deals with the study of the sewerage network in the village of Pavlovice u Přerova. Its main objective is to accomplish the passportization of the sewer network in the village, including the inspection of the waste water treatment plants. Based on the results of the passport, a hydraulic analysis of the sewer network was performed. The technical and operational state of the selected sections and the objects on the sewer network was evaluated. The draft measures for bad sections of the sewerage network and for the waste water treatment plants were taken on the basis of the evaluation. In the next part of the thesis, there were chosen methods of rehabilitation of the sewer network and the design of new waste water treatment plants. The proposed variants are also economically evaluated and compared. The thesis is complemented by the situation of the sewer network as a result of the passportization and also with the hydrotechnical situation.
The study of selected sewer network in an urbanized catchment
Korytář, Ivo ; Habr,, Vladimír (referee) ; Raclavský, Jaroslav (advisor)
This paper deals the case study of the chosen sewer system in the village Starý Mateřov. The study solves passportization of sewer, what is the base for creating technical condition mainly for three selected sections. According to the results from the technical conditions of the three selected sections were suggested suitable options of redevelopment. The options are compared in financial way. The last chapter suggests two possibilities how to deal with the sewage. The first option consists of the transferring waste water to the waste water treatment plant in Pardubice - Semtín. The second option suggests building a new waste water treatment plant in Starý Mateřov. The options are compared in financial way.
Effects of Municipal Wastewater Treatment Plant at Lopac Sinkhole Cave System
Ondruš, Martin ; Gruberová, Eva (referee) ; Malá, Jitka (advisor)
The aim of this thesis is to assess the impact of water outflow from wastewater treatment plant on karst rivers. The study was done in the northern area of Moravský kras protected landscape, where the impact of WWTP Ostrov u Macochy on a cave system Lopačské propadání was studied. As a part of this study a half-year monitoring was carried out, which consisted of water sampling every two weeks. In total, 13 water samples were taken from 7 sampling points. Moreover, flow rate, temperature, conductivity, oxygen concentration and pH were measured at the sampling point. Afterwards, the content of undissolved solids, COD, BOD, N-NH4+, N-NO2-, N-NO3-, NKi and total phosphorus were determined in the samples. The change of parameters in time on the sampling points and further along the flow of the river was evaluated from the measured values. The outflow values from waste water treatment plants were compared with the emission limits for surface waters and the values of river water parameters were compared with the environmental quality standards. It wasn’t proven that the outflow from the observed waste water treatment plant is negatively influencing the water stream. The most serious problems are: -The WWTP was designed for treatment of sewage from Ostrov u Macochy, which involved separate sanitary and storm sewers. After finishing the WWTP, a uniform sewer was built. -High concentration of total phosphorus on the outflow from WWTP. -Poor quality of Lopač brook water already before the outflow vent from WWTP.
Pilot Scale Solar Dryer Design
Plucar, Tomáš ; Létal, Tomáš (referee) ; Houdková, Lucie (advisor)
is Diploma’s thesis is addressing the issues of technical drying, principles and types of technical drying, solar drying possible usefulness of sewage sludge in the Czech Republic, its availability during the season, the legislation related to the processing of sewage sludge and design of pilot scale solar dryer.
Methods of sewage sludge thermal treatment
Rosendorfová, Lenka ; Pavlas, Martin (referee) ; Houdková, Lucie (advisor)
The first part of this diploma thesis targets in the formation of summary of methods of sewage sludge thermal treatment. Sludge is dangerous material rising from water treatment. Original water pollution is concentrated in sludge. Spectrum of the different methods of sludge disposal is very vast, thermal methods belong to the most advanced ones. Nowadays, legislative rules and regulations make more restrictive, hence sludge disposal is problematic because of economic and ecological view of point. The second part of this diploma thesis is dealt with perspective sludge management at the Central Waste Water Treatment Plant Prague concerning sludge drying and consequent sludge incineration.
Sludge Utilisation from Pulp and Paper Plant
Zemanová, Kateřina ; Houdková, Lucie (referee) ; Boráň, Jaroslav (advisor)
The contens of diploma thesis is description of paper and pulp production and analysis of contemporary problems with disposal of sludges rising on industrial waste water treatment plant. Accent is focuses on description of waste water treatment technique, characteristics of rising sludge and the ways of his liquidation in particular plant for pulp production. Fundamental part of this project is evaluation of power and economics balance of current sludge technology in company Biocel Paskov a.s. and suggested sludge management technology. Balances are based on data gained from measurement in laboratory and on data gained from literary research.
Drainage of waste water from the industrial area in Hulin city
Dohnal, Radek ; Vachovec, Roman (referee) ; Hluštík, Petr (advisor)
The subject of this thesis is to implement the passport of sewer system installation, technical assessment and evaluation of the technical condition of the entire sewer network in the industrial area, along with focus and plotting the current leadership of the sewerage system. It was also developed a hydraulic model of the entire solution sewer system. In the second part of the study is a proposal for an appropriate treatment system of wastewater. It was also developed a hydraulic model of the entire solution sewer system. In the second part of the study is a proposal for an appropriate treatment system of wastewater. In conclusion there is a financial assessment and comparison of different variants cleaning system in terms of investment and operating costs.
Effect of effluent from wastewater treatment plants on karst rivers
Schrimpelová, Kateřina ; Gruberová, Eva (referee) ; Malá, Jitka (advisor)
Karst rivers are special type of rivers because of their hydrography conditions. They usually flow from non-karst area and as soon as they reach in to the karst area they disappear underground. There, they flow through cavities until they reach the surface again. The aim of this thesis is to assess the impact of water outflow from wastewater treatment plant on karst rivers. The study was done in the central area of CHKO Moravský kras where the impact of two WWTP on a cave system Rudické propadání – Býčí skála is evaluated. As a part of this study a half-year monitoring was carried out, which consisted of water sampling once every two weeks. In total, 13 water samples were taken from 8 sampling points. Also 4 additional one-time samples were taken from the cave system. Moreover, flow rate, temperature, conductivity, oxygen concentration and pH were measured at the sampling point. Afterwards, the content of undissolved solids, CODCr, BOD, N-NH4+, N-NO2-, N-NO3-, P-PO43- and total phosphorus were determined in the samples. The change of parameters in time and during the flow in the river was observed from the measured values. The balance of pollutants in particular parts of the river was calculated. The outflow values from waste water treatment plants were compared to the emission limits for surface waters and the parameters of rivers were compared to the environmental quality standards. According to the results, it can be observed that the water quality improves after passing through the cavities. It was proven that the outflows from the observed waste water treatment plants are negatively influencing the water streams. The most serious problem is the wash up of sludge from WWTP Rudice and its consequent sedimentation in the river and/or outflow to the Rudické propadání.
