Hásová, Eva ; Dřímal,, Jiří (referee) ; Derco, Ján (advisor)
Diploma thesis will be dealt with the utilization of ozone wastewater treatment. Experimental part will be focused on study of ozone utilization in two different reactors (bubble column, jet loop reactor). Reactors will be compared by overall mass transfer coefficient and saturation concentration. Ozonization will be applied because of biological resistent and toxic compound 2-mercaptobenzothiazole disposal. Changes of biological decomposition will be measured and assessed by respirometric measurements.

Hazardous Chemical Substances and Preparations
Lacina, Petr ; Adamec, Vladimír (referee) ; Mika, Otakar Jiří (advisor)
The aim of this bachelor‘s thesis is to present a brief and current summary of hazardous chemical substances based on simultaneous laws in force. It introduces basic information and data on industrial hazardous chemical substances and basic characteristics of chemical warfare agents. This thesis also deals with documentation related to solutions for emergency events in connection with hazardous chemical agent escape – type plans, methodical sheets. The work results in a proposal for another methodical sheet focused on interventions of concrete hazardous chemical substance escape, i.e. hydrogen chloride. In this way the proposal can extend the methodical sheets for chlorine and ammonia currently in use. This thesis also presents list of toxic chemical, industrial and warfare substances for working up another methodical sheets.
