Removing organic contamination from water, using UV radiation.
Venská, Petra ; Vávrová, Milada (referee) ; Repková, Martina (advisor)
This diploma thesis focuses on possibilities of applications of UV radiation to remove pollutants from water. It summarizes sources of UV radiation and list their benefits and properties. The thesis characterizes so called advanced oxidation processes using UV light. Degradation pathways od pyridine and its derivatives especially halogenated pyridines are described. The photodegradability of pyridine and a rate of this reaction in model water is investigated in the experimental part. Also, the effect of concentration and dose of H2O2 is assessed. Gas chromatography was used to determinate concentrations of pyridine in samples.

Nitrogen and its compounds in wastewater
Venská, Petra ; Skoumalová, Marta (referee) ; Řezáčová, Veronika (advisor)
The bachelor thesis summarizes the possible forms of nitrogen and nitrogen compounds in wastewater and ways of elimination of these compounds including physical/chemical processes and biological processes. The physical/chemical methods described in the thesis are air stripping, breakpoint chlorination, sorption and membrane separation. The biological processes include nitrification, denitrification, anoxic ammonium oxidation and SHARON, CANON and OLAND systems. The experimental part is devoted to quantifying nitrates, nitrites and ammonium in wastewater samples using mobile analytical methods.
