Sanitation installation and gas installation in restaurant
Doubalová, Aneta ; Vaščáková, Alena (referee) ; Vrána, Jakub (advisor)
This bachelor thesis deals with health-technical and gas piping in the restauration. The topic grease trap is the theoretical part where the usage of function, principals, benefits, construction, installation. The computational and project part deals with sewerage, water and gas distribution system in this two floors part-cellar restauration. This bachelor thesis is written according to Czech and European regulations.

Sanitation installation and gas installation in a multifunctional building
Peřinová, Jitka ; Vaščáková, Alena (referee) ; Vrána, Jakub (advisor)
The task of the Bachelor's thesis is to develop a design of sanitary and gas installations in a given multifunctional building. The building has no basement and has four floors. In the first floor there is a bistro and a accommodation in the second floor. One dwelling unit is spread over the third and fourth floors. The theoretical part focuses on grease traps. I focus on their main functions, the choice of nominal size, montage and types of traps. The computational part contains all calculations used in the design of sewerage, water and gas pipelines, including their connection to utilities.

Study of preparations for fat separators
Gojkovic, Živan ; Ing.Dana Flodrová, Ph.D. (referee) ; Omelková, Jiřina (advisor)
Diploma thesis was concentrated at testing of a single commercial product designed as a lipid residue removal agent, applicable in grease trap vessel. Concept was, that product is to be tested for possible content of viable microbial culture with ability to utilize various kinds of vegetable oils and animal fats, by producing functional lipase. Four types of vegetable oils were used, and two fats of animal origin: olive oil, palm oil, rapeseed oil, sunflower oil, lard and beef fat. Determined fat characteristics were: point of the saponification, the acid value, the ester value and the peroxide value. Submerged cultivation was performed on specially composed medium in which the oil or fat of choice, was mixed later. Lipolytic activity and biomass growth measurement was performed using spectrophotometry, lipid degradation ability was measured using titrimetry. Based on results it can be stated that tested microorganisms, originated from product, and its lipase has ability to successfully utilize all of used fats and oils and thus, theoretically, remove its content from grease trap.

Degradation of fats in wastes
Artýszková, Jana ; Flodrová, Dana (referee) ; Omelková, Jiřina (advisor)
Submitted master’s thesis is focused on the study of possibilities of lipids degradation in particular wastewaters originating in food industry or restaurants. The effort is given to the employment of lipolytic activity presenting microorganisms. In the literature review, wastewater treatment with aim on the sludge management and fat separators are described, as a way how to pre-treat these wastewaters. In this part the enzymes lipases of microbial origin are researched from point of view of their production conditions and possible applications. The experimental part is dedicated to the research of optimization of cultivation conditions for lipases production employing selected microorganisms (Bacillus subtilis, Geobacillus thermodenitrificans, G. thermocatenulatus and mixed bacterial culture Thermus and Bacillus) and a commercial formulation (Sany Duo Spezial). Lipases production and growth of microorganisms are determined spectrofotometrically on various concentrations of lipids. Moreover, employing the solid nutrition medium, the effect of detergents onto the Bacillus subtilis culture was assessed, since detergents are generally abundant in this particular wastewaters. As a conclusion, vide supra mentioned microorganisms were characterized according to their abilities to degrade triacylglycerols.
