Personal care products as environmental contaminants
Babuš, Ondřej ; Stoupalová, Michaela (referee) ; Vávrová, Milada (advisor)
Synthetic musk compounds were first prepared artificially in the late 19th century. They have been used to perfume cosmetics, detergents and personal care products. The attention of many researchers has been focused on it recently, due to its high penetration into the nature which is a logical consequence of its great use. The main goal of this thesis is to determine the effect of the ultrafiltration on the concentration reduction of substances mentioned above in the industrial waste waters produced by the cosmetic company. Analytes from the sample were extracted using solid phase microextraction (SPME) and on gas chromatography analysis with mass spectroscopy (GC / MS) has been performed. The whole method was optimized and evaluated. Determination of the average efficiency of the ultrafiltration was made based on data obtained before and after ultrafiltration. Such efficiency determines the suitability of use of this method for removal of synthetic musk compounds from waste waters.

Industrial wastewater in Czech republic
Sikora, Petr ; Konečná, Eva (referee) ; Vondra, Marek (advisor)
The aim of this bachelor thesis is to provide a comprehensive insight into various aspects of industrial wastewater production in the Czech Republic. In addition to studying industrial wastewater in general, it also focuses specifically on winery wastewater. Wine production represents an alternative to another drink very popular among many Czechs – beer. To better understand this topic, the thesis combines a summary of theoretical knowledge with up-to-date statistics regarding production and emissions of industrial wastewater using data provided mainly by Ministry of the Environment of the Czech Republic, Czech Statistical Office, and Pollutant Release and Transfer Register. The results can be used for monitoring the development of quality and quantity of wastewater emissions during recent decades, as well as responses to various influencing events and factors. An overview of important legislation documents regarding this topic is included as well, followed by a brief selection of emission standards.

Indirect discharge of industrial wastewater into sewerage
Keprtová, Karolína ; Kolář, Jan
Wastewater discharge is one of the sources of environmental pollution. The main sources of wastewater pollution are industrial wastewaters. After treatment, industrial wastewater can be discharged directly into the recipient or indirectly into a sewerage network terminated by another stage of wastewater treatment. Indirect wastewater discharges are governed by the contractual relationship between the wastewater producer and the sewerage network operator. Limits for indirectly discharged wastewater are not set by legislation. It is only in recent years that the regulation of indirect discharges of wastewater has been promoted in Commission implementing decisions establishing best available techniques (BAT) conclusions, under Directive 2010/75/EU of the European Parliament and of the Council (BAT conclusions).
