Membrane technologies for agricultural wastewater treatment
Uhlířová, Marcela ; Touš, Michal (referee) ; Vondra, Marek (advisor)
This thesis deals with an agricultural wastewater treatment (liquid digestate) by membrane technology. There is a fundamental description of characteristics of membrane technology with regard to application of agricultural wastewater treatment in this thesis. Experimental device for treatment of liquid digestate is designed and it consists of three steps – microfiltration, ultrafiltration and reverse osmosis. The first step consists of four filters with different pore sizes (80, 25, 10 and 5 µm). The second step is ultrafiltration and the third and key step is reverse osmosis. In the final step monovalent ions such as NH4+ are separated. Reverse osmosis consists of two stage system which results in higher recovery. Three experiments were carried out in order to verify the efficiency of separation dissolved solids.

New technologies for an efficient operation of biogas plants
Uhlířová, Marcela ; Máša, Vítězslav (referee) ; Vondra, Marek (advisor)
This bachelor thesis is focused on new technologies enhancing efficient operation of biogas plants. The introductory part describes operation of biogas plant, its products and issues. The main part of the thesis deals with description of three progressive technologies concerning biogas plants such as dry fermentation, hydrothermal pretreatment and biogas upgrading to biomethane. For each technology there is a description, advantages and disadvantages with regard to their practical applicability.
