Alternative water sources on technological process in selected sector of industry
Bártů, Tomáš ; Mifková,, Tatiana (referee) ; Hluštík, Petr (advisor)
The task of the master’s thesis is a study focused on re-use and process wastewater in the company Kostelecké uzeniny a.s. The thesis contains a description of wastewater treatment plants, sewage flow and metabolic load on each water treatment processes. The thesis describes the limit requirements for technological processes within the enterprise. Few variants of the use of alternative water sources for technological processes on the basis of health conditions that has been designed for treating waste water from truck wash were considered in the thesis. Treated waste water is being re-used within the truck wash. Part of the proposal is also economic calculation and evaluation of return on investment.

Utilization of wastes
Šachlová, Žaneta ; Trachtová, Štěpánka (referee) ; Omelková, Jiřina (advisor)
Bachelor's thesis was focused on recovery from food processing industries, where she described the issue of the types of waste handling, recycling, processing by-products in the food industry, waste prevention. Attention is also given to food from industrial wastes such as sugar industry, production of starch and flour, meat, dairy, production of fats and oils, fruit and vegetable processing, production of malt and beer, wine, alcohol and yeast. There were considered suitable packaging materials in food, different waste treatment. Important microorganisms are set out using in waste treatment. At the conclusion of this study was designed a perfect procedure how to dispose with waste and included legislation on this subject.

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.

Využití mikroenkapsulace v potravinářství
Hofbauerová, Lucie
This bachelor's thesis is theoretical, it is focused on the use of microencapsulation in the food industry. The goal of this work is to develop a literature review, where current knowledge about the use of microencapsulation processes in the food industry will be processed. It includes an overview of individual methods and materials applied in the food industry. Among the methods listed here are, for example, coating, coacervation, extrusion, spray drying, electrospraying, electrospinning and others. The most frequently applied materials include polysaccharides, proteins, fats and waxes. Proteins include both plant and animal proteins. Polysaccharides include starch, chitosan, maltodextrins or gum arabic, animal proteins include milk proteins or gelatin, vegetable proteins pea, zein or chia seed proteins. For individual materials, their physical and chemical properties and examples of their application are given.

Biofilmy v potravinářském průmyslu
Škrobáčková, Monika
The work is focused mainly on bacterial biofilms, which are typical for the food industry. This work describes their history, definition, structure, formation and evolution, which includes their communication or quorum sensing (QS). Furthermore, the microorganisms that can form biofilms are described in detail in this thesis, such as the genera Escherichia, Staphylococcus, Enterococcus and others. The locations where biofilms are most commonly found in food industry such as dairy or meat industry are also described. Their detection and prevention methods are also described, which include individual tips on how to prevent biofilm formation itself. For example, sanitizers, natural antimicrobials, enzymes or nanoparticles are used.
