Harvesting of materials from wastewater and sludge
Boubínová, Marie ; Chorazy, Tomáš (referee) ; Hlavínek, Petr (advisor)
This bachelor thesis is focused on the issue of recycling raw materials from wastewater and sewage sludge with emphasis on phosphorus. The first part of the thesis deals with the problems associated with resources of phosphorus, the use of the legislative and recycling of phosphorus. Then, physico-chemical and biological methods of phosphorus recycling from wastewater and products of their further processing at WWTPs are discussed. Phosphorus recycling is also described in terms of the circular economy, which is explained at the end of the first part of this thesis. The second part of this thesis is a technical-economic research for a specific WWTP over 50 thousand. PE in the Czech Republic. The available technologies for recycling phosphorus from wastewater, sewage sludge and sewage sludge ash are described alsonhere. Then, the technologies are compared and evaluated.

Acquiring of phosphorus from sewage sludge
Boubínová, Marie ; Chorazy, Tomáš (referee) ; Hlavínek, Petr (advisor)
The diploma thesis is focused on phosphorus recovery from sewage sludge. In the first part of the thesis, research of phosphorus recovery from sewage sludge is explained. Reusing of phosphorus, a critical material of mankind, is expressed with the principles of the circular economy. The second part of the thesis defines the potential of phosphorus extraction from sewage sludge from medium-sized (Trutnov WWTP) and large (Modřice WWTP) wastewater treatment plant and a technical and economic study of the proposed phosphorus recycling system at these wastewater treatment plants is described.

The use of a dissolved air flotation for tertiary stage of wastewater treatment
Čmaradová, Miroslava ; Chládková, Helena (referee) ; Houdková, Lucie (advisor)
The thesis is focused on the area of wastewater treatment. There is a solution possibility of using flotation for the removal of phosphorus precipitates formed during the tertiary treatment of wastewater. The first part is devoted to a general description of wastewater treatment, there is also described as a flotation separation technology and precipitation of phosphorus. The second part is practically oriented. It describes the experimental equipment used for the precipitation of phosphorus and subsequent removal of the precipitate flotation, during the experiment and the results obtained.
