Legal instruments of the protection of water quality - Abstract The purpose of my thesis is to analyse a system of legal instruments of protection of quality ground and surface water. The reason for my research is fact that quality of water has an impact not only on every human being but also on the whole planet Earth because there is no life without it. The thesis is composed of six parts - introduction, four main chapters and conclusion, each of them dealing with different aspects of water protection. Short introduction outlines total amount of water and main problems lie with the actual amount of fresh water and quality of this water. Chapter One defines major sources of pollution which are point, non-point and emergency sources of pollution. The next two parts of this chapter contain actual state of quality both surface and ground water in Czech Republic. Chapter Two concentrate on relevant international, European and Czech legislation in water protection. The chapter consists of three parts. Part One focuses on international law which is based on bilateral and multilateral treaties. Part Two investigates the European Union water law with focusing on primary and secondary sources of law. Part Three looks at Czech water law. Chapter Three is subdivided into two parts and provides an outline of main aims...

This Master’s thesis deals with sanitation installation in historic building. The theoretical part of the topic analysis deals with the issue waste water discharge from the building and ground floor. Furthermore, the theoretical solutions are processed sanitation installation and variants of it. Preferable variant is finalized the details of the implementation of the project.

Presented PhD theses deals with evaluation of use of algal biofilms for nutrients removal from wastewater. The integral part of research was estimation of the comprehensive benefit of the presented technology, including biomass production and phosphorus recovery. The algal biofilm was able to remove 98 % of phosphorus after 24 hours when the PO4-P concentrations in inflowing water ranged from 3 to10 mg.L-1. Different patterns of phosphorus and nitrogen removal were observed. Daily quantity of removed NO3-N ranged from 2 % to 25 % and was highly depended on solar irradiance. The studied biofilm system has a high efficiency for phosphorus removal and, therefore, has great potential for integration into wastewater treatment processes.

The subject of the diploma thesis is the evaluation of the cleaning efficiency at the chosen sewage treatment plants and their subsequent comparison. The thesis is divided into the theoretical and practical part. The theoretical part deals with the legislation of the Czech Republic and the European Union in the field of WWTP and waste water treatment, it also deals with the types of waste water, its composition and the process of its cleaning, especially it is focused on the activation process. The practical part contains a description of the objects on the technological line of Mikulčice WWTP and WWTP Starý Poddvorov. Another part of the thesis evaluates the hydraulic load, the substance load and the cleaning efficiency at individual treatment plants during the monitored years 2015-2017. The individual results are graphically processed. The operational results are described in the evaluation of the results and the procuration are proposed for improving the efficiency of the cleaning, namely the addition of the technology of WWTP Starý Poddvorov for the chemical precipitation of phosphorus.
