Natural wastewater treatment system in Surabaya, Indonesia
Semrádová, Tereza ; Zedník, Ondřej (referee) ; Kriška-Dunajský, Michal (advisor)
In developing countries, constructed wetland is a possible way to improve the long-term quality of domestic wastewater effluent. It is a treatment plant that reflects the climatic conditions, the quality and quantity of the wastewater discharged and the economic conditions of the country. It offers simplicity in terms of operational requirements. These statements are also addressed in the design work of a constructed wetland in the Indonesian city of Surabaya. The design itself is preceded by an analysis and understanding of the existing wastewater management, which is currently very minimalist in the locality. The thesis develops a proposal for a suitable and sustainable community-based natural wastewater treatment solution for an urban area of up to 1 000 inhabitants. The proposal considers the technical-economic-social aspects and should thus lead to higher efficiency and longer lifetime of the proposed treatment plant. The solution also includes operational recommendations to ensure the long-term operation of the treatment plant. There are hardly any municipal treatment plants in the area, so the possible implementation of a constructed wetland will be the first solution of this kind, which will either ensure future expansion based on positive experience or, on the contrary, be rejected due to unsuitable operation in local conditions.

Persistent water pollutants: case of ethylenediaminetetraacetic acid in the Czech Republic
Prášek, Jan ; Šauer, Petr ; Keprtová, Karolína
Reuse and recycling of products composed of natural matter is relatively without significant environmental problems. However, recycling of products produced using modern synthetic technologies often brings new challenges. Our analysis has shown that substitution of citric acid with artificial substance of ethylenediaminetetraacetic acid causes important environmental problems. The case study carried out in the Elbe river basin shows that the ethylenediaminetetraacetic acid concentration standard has been exceeded, particularly from confluence of the Vltava and Elbe rivers. Open questions and tasks for future technological development and environmental policies are formulated, particularly the idea to replace artificial substances with nature-based ones. This would enable better introduction of circular economy ideas in the use of resources.

Natural wastewater treatment plant project for the municipality of Hačky
Kulichová, Jana ; Pumprlová Němcová, Miroslava (referee) ; Kriška-Dunajský, Michal (advisor)
The aim of the thesis is research, description, and subsequent calculation and design of the natural wastewater treatment plant. The conclusion is the processing of project documentation. The thesis is divided into the theoretical and practical parts. In the theoretical part, the aim is a general description of the location and research of natural wastewater treatment plant technologies for small municipalities. In the practical part, there is designed project documentation, which will be used as an input basis for zoning management and building permit.

Project of a natural wastewater treatment plant for the municipality of Oponešice
Kraváček, Václav ; Zedník, Ondřej (referee) ; Kriška-Dunajský, Michal (advisor)
The diploma thesis deals with the design of a natural wastewater treatment plant for the municipality of Oponešice. The introduction of the thesis focuses on general research presenting the issue of natural wastewater treatment plants (WTP). Except for a short introduction of natural treatment plants, the related legislative regulations are presented in the introductory part, the work is devoted in more detail to the presentation of individual monitored indicators of wastewater pollution and a description of individual technological elements at root treatment plants. The second and main part of the work is the complete design of the wastewater treatment plant for the village of Oponešice. First, attention is paid to collecting information about the given locality. Next follows the design of the technical solution of the treatment plant itself, in which care was taken to meet all the requirements placed on treated wastewater, with an effort to design the best available technology for the municipality of Oponešice. Within individual objects, input parameters and subsequent calculations are always given, accompanied by a description of individual details. As the main stage of cleaning, a two-stage vertical system of the so-called Austrian type, supplemented by pre-cleaning with the help of an anaerobic separator, is proposed. At the end of the work, an evaluation of the overall efficiency of the proposed technology is described and a confrontation with the applicable legislation is carried out. Last but not least, an important part of the work includes the preparation of complete project documentation (drawings and textual parts), which is to serve as input material for the issuance of zoning regulations and building permits.

Natural wastewater treatment plant project for the municipality of Skřipov
Hubený, Michal ; Pumprlová Němcová, Miroslava (referee) ; Kriška-Dunajský, Michal (advisor)
The diploma thesis deals with the substantive design of a natural wastewater treatment plant of the French system for the municipality of Skřipov. The proposed sewage treatment plant has an expected size for 800 EO. The whole thesis is divided into two parts. In the theoretical part, the details of the area under consideration, especially the municipality of Skřipov, are presented and thoroughly described. Furthermore, a general research on the topic of natural wastewater treatment plants was written by the author of the thesis. In the theoretical part of the thesis there is also a detailed description and introduction to the system of French vertical wastewater treatment plants. The practical part is the design of a natural wastewater treatment plant for the municipality of Skřipov. The thesis describes in detail the design procedure of the treatment plant and its calculations. The work includes project documentation that will serve as a basis for the issuance of a building permit.
