The potential of microfiltration and ultrafiltration processes as a methods of ayays of water treatment plants
Zelený, Zdeněk ; Biela,, Renata (referee) ; Kučera, Tomáš (advisor)
This bachelor´s thesis deals with the possibilities od using membrane filtration in water treatment process intensification. The introduction presents the formativ and development of these technologies, their progressive expansion and application. Then deals with specific properties and possibilities of using microfiltration and ultrafiltration membrane modules. Part of this work is the description of the materials used for making membranes, their advantages and disadvantages. Below are the possible approaches to setting and operation of filtration technology in drinking water supply for residents. Another important point of this thesis is the description of cleaning, maintenance and any repairs or expansion of membráně modules depending on the method of operation and the type of memebrane module. Another point mentioned in this study is the description of both methods of testing the integrity of membranes, direct and indirect. Testing of memebrane integrity is considered one of the most important advantages over alternative membrane filtration water treatment methods. The final part is devoted to recent findings from on going research a concrete example of the membrane device installed in the Czech Republic.

Anaerobic membrane bioreactor (AnMBR) for food industry wastewater treatment.
Polášek, Daniel ; Bodík,, Igor (referee) ; Rusník,, Igor (referee) ; Hlavínek, Petr (advisor)
The most significant environmental problems related to the food industry is water consumption and pollution, energy consumption and waste production. Most of the water that does not become a part of the products ultimately leaves plants in the form of wastewater, which is often very specific and requires adequate handling / treatment / disposal. For the purpose of this thesis, brewery industry was chosen, because of its very long tradition in the Czech history and culture. Anaerobic technologies are applied for still wider range of industrial wastewater treating. In general anaerobic membrane bioreactors (AnMBRs) can very effectively treat wastewater of different concentration and composition and produce treated water (outlet, permeate) of excellent quality, that can be further utilised. At the same time, it can promote energy self-sufficiency through biogas production usable in WWTPs / plants. Main disadvantages include unavoidable membrane fouling and generally higher CAPEX / OPEX. Within the framework of Ph.D. studies and related research activities, immersed membrane modules for anaerobic applications were selected and lab-scale tested (designed and assembled laboratory unit), an AnMBR pilot plant was designed, built and subsequently tested under real conditions - at Černá Hora Brewery WWTP (waste waters from the brewery and associated facilities). The pilot AnMBR and the technology itself has been verified over more than a year (5/2015 – 11/2016) of trial operation - the initial and recommended operational parameters have been set up, minor construction adjustments / modifications and measurement & regulation optimizations have been made, the recommended membrane cleaning and regeneration procedure has been verified. Last, but not least, conclusions and recommendations of the trial operation were summarised - some key findings and recommendations for further operation, use and modifications of the existing AnMBR pilot plant are presented.

Energy performance of membrane processes
Maršík, Miroslav ; Kubík, Jiří (referee) ; Hluštík, Petr (advisor)
The thesis deals with energy demands of wastewater treatment plants. The content is focused on inclusion of membrane modules to the wastewater treatment process. Two possible options of wastewater treatment are compared; first, convetional mechanical-biological wastewater treatment plants with activation and installable tank; on the other hand, plants with activation with membrane module. In the practical part, three possible options of intensification are suggested. In the first part, new mechanisms for the plant are projected, in the second part, the energy demands of this tecnological equipment are treated, and in the last point, the item bugget is processed. The comparison of investment and operating costs is made in the conclusion of the thesis.

Use of recycling membrane technology for industrial waters
Vykydalová, Adéla ; Mergl, Václav (referee) ; Repková, Martina (advisor)
The bachelor thesis deals with the recycling technology of industrial wastewater – more precisely, the laundry industry. The semi-operational pilot unit of ASIO TECH was used for testing this technology. The unit includes membrane processes – ultrafiltration, reverse osmosis and flotation process. There were 8 physico-chemical parameters selected for assesing the quality of wastewater and treated water. The tested semi-operational unit is suitable for cleaning laundry wastewater. The purified water can be used in the next washing process or for the water source for the steam generator.
