Properties of anaerobic sewage sludge from small producers
Pospíšil, Jaroslav ; Kriška-Dunajský, Michal (referee) ; Hyánková, Eva (advisor)
The bachelor thesis deals with today's wastewater treatment from small producers and characteristics of primary sludge. Work is focused on natural ways of wastewater treatment. The main attention is devoted to the primary sludge. In the next section are based on laboratory tests, where samples are tested properties. There is tested the primary sludge from the mechanical pre-treatment, and namely from the sedimentation tank.

Sledování vybraných parametrů čistírenského kalu
Hirschová, Linda
This thesis deals with the evaluation and characterization of sludge parameters relevant to the drying process and subsequent energy recovery. The main parameters monitored are the dry matter of the sludge, the loss on ignition, the calorific value of the primary, thickened and dewatered sludge. Marginally, the paper also deals with the evaluation of pH, conductivity and oxidation-reduction potential. In particular, the characteristic of dewatered sludge entering the drying process is central. The dry matter of the dewatered sludge ranged from 13.5 to 25.7 %. The measured values of the calorific calorific value of the dewatered sludge ranged from 10.2 to 17.9 MJ∙kg-1, an assessment observed a dependency between the loss on ignition and the calorific value of the sludge. The impact of thickening (gravitational, mechanical) and stabilization (aerobic, anaerobic) sludge technology is taken into account in the evaluation. Part of the thesis deals with statistical evaluation of the effects of seasonality on monitored parameters.
