Efficacy of combined dosing of coagulant and flocculant on wastewater sludge dewatering
Pániková, Kristína ; Novotná, Věra (referee) ; Hrich, Karel (advisor)
Sludge treatment and disposal are one of the most important parts of sewage treatment. These are economically challenging parts, and therefore emphasis is placed on effective dosing. The dose should be as small as possible but also the highest dry matter output. The main target of this diploma thesis is therefore to show that it is possible to achieve the same or better degree of drainage of the sludge if different flocculant/coagulant ratio is applied to the sludge. Diploma thesis deals with determination of the optimal combination of chemical doses during sludge dewatering. The thesis contains two parts, practical and theoretical. The theoretical part consists of research, overview of processed research and works in the area of sludge dewatering. The second part is a description of laboratory measurements and evaluation of results.

Optimization of Fe2(SO4)3 dosage at selected branched WWTPs in Prague
Kadlecová, Petra ; Tesařová, Eva (advisor) ; Kalíková, Květa (referee)
This bachelor thesis focuses on the optimization of the dosage of the precipitant Fe2(SO4)3 in selected wastewater treatment plant branches. Three such branches, connected to the integrated sewerage system and equipped for stormwater management practices, were observed. The goal of this thesis was to limit the dosage of iron sulfate during periods of heavy rainfall. Restriction in the dosing was implemented by deactivating the iron sulfate pump at times when the hydrodynamic vortex separator was in use. Annual savings for the individual wastewater treatment plants amount to the range of 1,48, 3,68 and 4,01%.
