Reuse of treated wastewater in paper and textile industry
Matysíková, Jana ; Vachovec, Roman (referee) ; Hlavínek, Petr (advisor)
This thesis deals with Advanced oxidation processes (AOP) and its aplication for textile wastewaters treatment and reuse. AOP is a modern technology which currently recieves increased attention due to it´s high efficiency in removing resistant and hardly-degradable pollution. Thesis consists of search and practical part. Search part is created by three chapters. First chapter describe briefly wastewater reuse. The second chapter deals with Advanced oxidation processes. AOP principle, AOP division and descriotion is included with the strong focus on the ozonation technology. The third chapter presents the textile industry and its wastewaters. The practical part of this thesis consists of two chapters. Chapter 5 describes testing of textile wastewaters decoloration by ozonation in the selected textile copany and its results. This results are used in chapter 6. Chapter 6 is the study of textile industry treatment and reuse in the selected textile company. This study contains the design of two options for wastewater treatment and reuse in the textile processes.

Application of membrane technologies for the production of drinking water from the effluent from the WWTP
Minich, Marek ; Mergl, Václav (referee) ; Repková, Martina (advisor)
The Master’s Thesis deals with the application of membrane technologies in the production of drinking water from the effluent of a municipal wastewater treatment plant (WWTP). There were two types of pressure-driven membrane processes selected – ultrafiltration and reverse osmosis, to achieve water production of the required quality. For the needs of the diploma thesis, an already existing pilot-scale membrane unit of the ASIO TECH Company l.t.d. was used. There were 44 physical, chemical and microbiological parameters observed to assess the quality of the produced water and also the input water (effluent from the WWTP). None of the afore mentioned parameters exceeded the limit values, more specifically the highest limit values issued by the Decree 70/2018 Coll. However, the produced water cannot be considered as drinking water because of its low mineralisation. Before its potential application in practise, it is therefore necessary to choose an appropriate method of remineralisation as well as to follow all the other legislative requirements for the drinking water, which have already been out of the scope within the Master’s Thesis.

Proposal for the use of gray water in the swimming area "Kraví hora" with a view to completion of the wellness center
Běloušková, Pavla ; Plotěný, Karel (referee) ; Biela, Renata (advisor)
Greywater is the leftover water from baths, showers, hand basins and washing machines only, what implies that it is free of faeces and urine. Greywater can be recycled as processing water (whitewater) for toilet and/or urinal flushing or landscape irrigation. Energy recovery from greywater looks also very promising. The subject of this thesis is short research on the issue of the use of greywater in the first part, the following chapter provides examples of the use of greywater in practice. Practical part of thesis provides suggestion of use of greywater and their heat potential in swimming area Kraví hora with regard to completion of wellness centre. This part also includes economical analysis of suggested recycling.
