Optimization of the coagulation procedure for wastewater treatment
Švábová, Martina ; Mravcová, Ludmila (referee) ; Repková, Martina (advisor)
This bachelor thesis deals with the optimization of the determination of the chemical oxygen demand in the test tubes and the optimization of the coagulation process for the external company. COD is one of the basic analysis for all types of water, although there are numerous environmentally-unfriendly agents in case of using a standard version produced. Therefore, an alternative method of using the test tubes was used, the procedure of which has been modified from ČSN ISO 15705 and is now available to the public. The aim was also to optimize the coagulation process in the treatment of wastewater from an industrial paintshop. The minimum dose of coagulating agent occurring in the instructions for usage was disproved and the pH value at which aluminium sulfate as a coagulating agent was proposed.

Industrial wastewater in Czech republic
Sikora, Petr ; Konečná, Eva (referee) ; Vondra, Marek (advisor)
The aim of this bachelor thesis is to provide a comprehensive insight into various aspects of industrial wastewater production in the Czech Republic. In addition to studying industrial wastewater in general, it also focuses specifically on winery wastewater. Wine production represents an alternative to another drink very popular among many Czechs – beer. To better understand this topic, the thesis combines a summary of theoretical knowledge with up-to-date statistics regarding production and emissions of industrial wastewater using data provided mainly by Ministry of the Environment of the Czech Republic, Czech Statistical Office, and Pollutant Release and Transfer Register. The results can be used for monitoring the development of quality and quantity of wastewater emissions during recent decades, as well as responses to various influencing events and factors. An overview of important legislation documents regarding this topic is included as well, followed by a brief selection of emission standards.

The Issue of Industrial Wastewater Treatment and its Inclusion in Biology Education
Rychtecká, Karolína ; Skýbová, Jana (advisor) ; Říhová, Dagmar (referee)
The topic of the diploma thesis is "The Issue of Industrial Wastewater Treatment and its Inclusion in Biology Education." The aim of the thesis is to familiarize the reader more deeply with industrial wastewater, to find out how the general population perceives the issue, and specifically to propose and verify in practice how the topic could be included in the teaching of natural history. The work consists of a theoretical and a practical part. The theoretical part of the work is devoted to the definition of industrial wastewater and its composition. It characterizes selected industrial wastewater and treatment processes that are used to remove pollutants in industrial wastewater. It also marginally touches on the topic of water management in the industry. The chapters of the theoretical part also summarize the impact of wastewater pollution in relation to humans and the environment. The work also includes a section dedicated to legislation related to industrial wastewater treatment. The conclusion of the theoretical part of the work is devoted to teaching methods suitable for the inclusion of the issue of industrial wastewater in teaching at secondary schools. The practical part is devoted to own research to find out the perception of the population about the issue of wastewater treatment and...

Indirect discharge of industrial wastewater into sewerage
Keprtová, Karolína ; Kolář, Jan
Wastewater discharge is one of the sources of environmental pollution. The main sources of wastewater pollution are industrial wastewaters. After treatment, industrial wastewater can be discharged directly into the recipient or indirectly into a sewerage network terminated by another stage of wastewater treatment. Indirect wastewater discharges are governed by the contractual relationship between the wastewater producer and the sewerage network operator. Limits for indirectly discharged wastewater are not set by legislation. It is only in recent years that the regulation of indirect discharges of wastewater has been promoted in Commission implementing decisions establishing best available techniques (BAT) conclusions, under Directive 2010/75/EU of the European Parliament and of the Council (BAT conclusions).

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.
