Název v původním jazyce

The effect of operational temperature on dewatering characteristics of digested sludge

Popis výsledku v původním jazyce

Dewatering properties and sludge structure of anaerobically digested sludge were studied in relation to an increasing operational temperature. Sludge samples were taken from 5 pilot-scale CSTR reactors treating municipal sewage sludge with working volumeof 20 L and operating at 33, 35, 37, 39 and 55°C, respectively. The main parameters of interest were capillary suction time (CST), concentration of extracellular polymeric substances (EPS), charge density of the extracted EPS, filterability (dry solidscontent after vacuum filtration), compressibility (dry solids content after pressing) and concentration of fine particles in the liquid phase (turbidity).##Sludge from the reactor working at 55°C (thermophilic) contained the most fine particles in the liquid phase, which remarkably deteriorate d filterability of the sample, however when subjected to an external pressure, the sludge reached the highest dry matter content of the sludge cake. Sludge originating from the reactor working at 3
