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.
Chemical dosing optimalisation during by wastewater sludge dewatering
Pániková, Kristína ; Novotná, Věra (referee) ; Hrich, Karel (advisor)
Bachelor thesis deals with chemical dosing optimisation during by wastewater sludge dewatering. The thesis has two parts, practical and theoretical. Theoretical part contains basic information about thickening, destabilization and stabilization, flocculants, methods of measurement and final sludge treatment. The evaluation of laboratory measurements and presentation of the results are in the practical part.

Compounds for reduction of cyanobacterial blooms
Jančula, Daniel ; Maršálek, Blahoslav ; Drábková, Michaela
This work focus on possibilities how to reduce cyanobacterial blooms by ecological compounds with emphases on biodegradable algicides, natural products, coagulants and biological preparations for reduction of nutrients in sediment. Their ecological implications and utilisation for water bodies is discussed too.
