Optimization of method for evaluation ETICS dirtiness
Gabriel, Jindřich ; Žák,, Antonín (referee) ; Žižková, Nikol (advisor)
This diploma thesis deals with the issue of adhesion of pollution to the final surface treatments of the ETICS system. The theoretical part deals with important factors and processes that affect the degree of adhesion of pollution. The practical part of the diploma thesis follows the diploma thesis of Ing. Jakub Krejčík. Optimization of test methods for simulation of artificial pollution on tested samples was proposed. These samples were then evaluated in the laboratory and also compared with plasters that were exposed to real pollution from the natural environment.
Design of a filter unit for waste gas cleaning
Volánka, Lukáš ; Wegschmied, Roman (referee) ; Jecha, David (advisor)
This bachelor's thesis focuses on the design of the filtration unit and on particulate matter, or PM, which is still a significant contributor to air pollution. The first chapter describes the basic properties of these pollutants and their influence on the design of the separator. The next chapter briefly discusses the current legislation in the Czech Republic dealing with emission and air pollution limits. In the third chapter, which is also the last of the theoretical part of the thesis, the individual methods of removal of PMs are presented and explained. The practical part follows, mainly devoted to the design of the filtration unit for the given case, which ends with the measurement of emissions and a brief evaluation of the results.
Měření emisí zápachu a tuhých znečišťujících látek z intenzivního chovu drůbeže
BELKA, Daniel
As agricultural production grows, the focus is on improving air quality, which affects not only residents around farms, but also climate change on a global scale. This thesis deals with the measurement of particulate pollutants and odor emissions in intensive poultry farming. The measurements were carried out at the Farma U Lesa in Sudoměřice u Bechyně in the spring and autumn of 2018. The production specific emission of odorous substances into the air was evaluated using dynamic olfactometry according to ČSN EN 13 725, which ranged from 0.01 to 0 according to the fattening cycle phase, 3 OUE. Ks-1. s-1. Compared to the BREF reference document, which lists emission odor values from 0.032 to 0.7 OUE. Ks-1. s-1 the measured values on the farm Mr. Šonky came out very low. Dust particles of PM10 fraction were measured according to the ČSN EN 12 341 methodology for the measurement of dust particles and the production specific emission of PM10 particles was found, which during the whole fattening cycle was measured to a maximum of 0.0025 kg. Ks-1.year-1. The measurement results were compared with the BREF reference document, where the maximum permissible production of solid pollutants of this fraction from 0.004 to 0.025 kg. Ks-1.year-1. In comparing the measured dust emission values with the BREF, the production of harmful emissions was very low.
Porovnání koncentrace tuhých znečišťujících látek uvnitř stáje v rozdílných technologiích velkochovů drůbeže
ŠONKA, Jan
Intensive poultry farming releases contaminated gases, odors, microorganisms and large concentrations of dust particles. Dust particles have a negative effect on the health of humans and animals. Dangerous particles with a diameter of less than or equal to 4 m, which can travel to the gas exchange area of the human respiratory system, pose a great health risk. The aim of this thesis is to measure PM10 dust particles in intensive poultry farms depending on the age of the chickens. Another goal is to compare the results between farms and compare them with the values shown in Table 5.15 on page 157 of document Final TWG meeting for review of the IRPP (Integrated Pollution Prevention and Control) BREF (Reference Document on Best Available Techniques). The measurements were carried out at the farm Alas a.s. in Hartmanice and at the farm Farma u lesa a.s. in Sudoměřice u Bechyně.

FARA, Radek
Topic of this thesis is comparsion of emission concetration of solid pollutants in intensive poultry farming with different technologies. Measurement was done in cage system and two alternative poultry housing systems in company International poultry testing based in Ústrašice. For measurement of dust particles was used measurement device DUSTTRAK II 8530, own measurement has been done continuously for 24 hours with record every 3s. Dustiness was tracked in size fraction PM10. This dust particles can negatively influence health of employees and reared poultry. By measuring and following evaluation was found, that lowest value of dust particles was achieved in cage housing system. Considering health protection of employees and requirements for poultry wellfare is necessary keep dustiness of stable enviroment on lowest level.
Emissions of solid pollutants
Strnad, Ondřej ; Lisá, Hana (referee) ; Baláš, Marek (advisor)
The thesis deals with issue and properties of solid particles of anthropogenic origin. It describes the principles and technologies for removing them from the flue gas flow and avoid-ing leakage into the atmosphere. It focuses on types of separators, especially mechanical sepa-rators. The work includes an experimental part involving obtaining data characterizing the cyclone separator.
PM Exposure in Climbing Gyms: Case study of two climbing walls in Prague
Bartošová, Nikola ; Bendl, Jan (advisor) ; Makeš, Otakar (referee)
This thesis deals with the issue of high exposure of dust particles PM10, PM2.5 a PM1 in two specific climbing gyms in Prague. The source of these particles is linked to the use of magnesia alba that the climbers use to dry up the skin of their hands. The thesis analyzes the expected correlation between the dust particles concentration and the current number of visitors of the climbing gym. The dust particles are proven to have a negative effect on the health of individuals. The dust particles measured in this thesis are able to penetrate the respiratory tract. The size segregated aerosol was measured using DustTrak DRX. It is a laser nephelometer. In one of the gyms, a gravimetric analysis was performed, using a Harvard impactor that measures the PM10 concentration. All measurements were performed within the period of 20.4.2016 -5.2.2017. In the climbing center Mammut, the PM10 exposure was measured at 0,125 - 0,167 mg*m-3 , which could quadruple in the most frequented time periods. The climbing gym SmíchOFF measured the maximum levels of PM10 at 0,368 - 0,901 mg*m-3 . Both climbing centers exceeded the average daily imission limits for PM10 and PM2.5. From the health perspective, it is recommended to prevent such high exposure levels or lower the concentrations in the climbing gyms by suitable...
Posouzení faktorů ovlivňujících koncentraci prachových částic při lisování píce
ŠŤASTNÝ, Vladislav
The objective of this diploma thesis is to assess the factors affecting the concentration of dust particles during forage pressing. For this purpose, five presses for square bales and five presses for round bales were selected. They were harvesting different kinds of straw. Thanks to measurement using an aerosol monitor, the concentration of dust particles during the harvest was detected. The measured values were evaluated and the amount of concentration of the dust particles between the square and round bale presses was compared. There were also set the methodological steps of the measurement procedure.
Posouzení faktorů ovlivňujících koncentraci prachových částic při sklizni píce
MACH, Milan
This diploma thesis deals with the concentration of dust particles during harvesting of forage, namely hay, straw and fed forage. The measurements were always carried out on another land in the Vysočina Region. DUST TRAK II 8530 instrument was used to measure dust concentration. Each measurement was performed for ten minutes.
Koncentrace tuhých znečišťujících látek emitovaných do okolí velkochovů drůbeže.
BLAŽEK, Petr
In this diploma thesis I focus on poultry farms, as a source of dust particles, which are taken from the breeding establishment to the surroundings of poultry breeding. The first theoretical part of the thesis is focused on dust, dust particles and their sources, as well as on housing of poultry and on BAT technology. These particles can be dangerous not only for the animals but also for the staff working in the vicinity of the farm animals. In the second, practical part of the thesis, I focus on the measurement of dust particles PM10 using the DUST TRUK II measuring instrument in a selected broiler breeding facility, as well as on the processing of measurement results and comparison with hygienic regulations and already measured values.
