Originální abstrakt

The paper presents results of laboratory measurements of viscosity and density of activated and return activated sludge. The solubility of oxygen in sludge liquor was measured and results were compared with solubility of oxygen in pure water. Results of viscosity measurement show, that sludge containing up to 1% of dry solids can be considered as a Bingham fluid, while sludge with dry solids content above 1% should be described by Herschel-Buckley model. Sludge density is only slightly higher than density of water, with increasing dry solids content the density increases negligibly. The amount of air dissolved in sludge liquor can be calculated using Henry s law constants for water, because solubility of oxygen in water and sludge liquor differs only minimally.
