Design of WWTP at locality with extreme demands on quality of treated wastewater
Krupica, Radek ; Vachovec, Roman (referee) ; Hlavínek, Petr (advisor)
This diploma thesis deals with the wastewater treatment technologies by means of which high quality of the treated wastewater is attained, especially with regard to removing nutrients. The introduction of the thesis contains, among others, descriptions of the reserves in the Czech Republic where it is extremely important to insist on the highest quality of the discharged wastewaters. Then follows a summary of the quality requirements on the discharged wastewaters as stipulated in the legislation. Furthermore, I analyse the impact of the nutrients – nitrogen and phosphorus – on the environment and the principles of their removal from the wastewaters. In the next section I concentrate on the technological processes by means of which the required quality of the wastewater is achieved. The conclusion includes a list of technologies used as the tertiary wastewater treatments with emphasis on membrane technologies. The second part of my thesis is a study of a project of a wastewater treatment plant (WWTP) with membrane technology for the villages of Sloup and Šošůvka located within the protected landscape area of Moravian Karst.

Design of Biogas Cleaning Technology
Šrámek, Zbyněk ; Milčák, Pavel (referee) ; Milčák, Pavel (referee) ; Lisý, Martin (advisor)
Thesis aims to design suitable technology for biogas treatment so that its output can be used as a fully equivalent fuel for vehicles. First part introduces reader into an area of biogas treatment. Second part describes in detail chosen method, technology of membrain separation. In third part, current conditions in Czech republic were discussed. Fourth part adresses the aplication of membrane technology into existing biogas station via side-standing reaserch container. The end of the thesis is focused on selection and proper desing of blower, which will be transporting raw biogas from biogas fermenters into research container.

Removal of emerging contaminants from water by a hybrid membrane-catalytic oxidation process
Bourassi, Mahdi ; Klusoň, Petr (advisor) ; Bendová, Magdalena (referee) ; Granger, Pascal (referee)
Emerging contaminants were detected in different surface waters around the globe. These active molecules affect the environment even at trace concentrations. They are sourced mainly from wastewater treatment plants. These contaminants persist the conventional wastewater treatments and gain their way to the environment. This can cause different complications: bioaccumulation, antibiotic resistance, and environmental degradation. The presented Ph.D. thesis is focused on the treatment of wastewater loaded with persistent pollutants. This thesis aimed to evaluate the membrane separation technology and the catalytic wet air oxidation (CWAO) process to associate them in a hybrid process to address this issue. The first part of the hybrid process is focused on challenges faced with the membrane separation process, mainly fouling and selectivity. This part gathers 6 publications all focused on wastewater treatment with membrane separation. As a starter, the review covers the issue presented by the emerging contaminants and the potential of the membrane process for water recovery. The review highlighted the advantages and challenges (fouling and selectivity) of the membrane process. The chapter about membrane fouling gathers two publications: "Removal of ibuprofen from water by different types of...

How can we best eliminate pharmaceuticals from wastewater?
Bourassi, Mahdi
Persistent pharmaceutical occurrence in different lakes and rivers usually originates from live stocks, agriculture, aquaculture, households, and hospitals. The presence of these compounds in the ecosystems leads to fatal consequences. Pharmaceuticals can threaten microorganisms in the environment, either causing its deterioration or allowing pathogens to gain resistance against antibiotics and medical treatments. These occurrences in the environment questions the ability of conventional treatment to remediate pharmaceutical wastewater.
