dcterms:description
Results are presented from laboratory measurements of viscosity and density of activated and return activated sludge. Solubility of oxygen in sludge liquor was measured and results were compared to solubility of oxygen in pure water. Viscosity measurements show that sludge containing up to 1% dry solids can be considered a Bingham fluid and sludge with dry solids content above 1% should be described using the Herschley-Buckley model. Sludge density is only slightly higher than water density and with increasing dry solids content increases negligibly. The amount of air dissolved in sludge liquor can be calculated using Henry's Law constants for water because the solubility of oxygen in water and sludge liquor differs minimally.
