High-shear and pressure activated sludge treatment : solid-liquid separation

Creator:: Coddington, Charles William
Abstract:: Since the development of the activated sludge process in 1913 many attempts have been made to improve it. One approach has been to increase the oxygen available to the bio-mass. This study combined the use of elevated pressure and high-shear mixing to increase the oxygen transfer. The conventional method of...

The effect of elevated pressure on the activated sludge process

Creator:: Godsil, Patrick James
Abstract:: A study of the effect of elevated pressure on the activated sludge waste treatment process is presented. The method of study involved a comparison of two laboratory, batch type, activated sludge units. One unit was operated at atmospheric pressure as a base control and the other operated at elevated pressures...

The effect of elevated pressure and high shear on oxygen uptake rates in activated sludge

Creator:: Streebin, Leale E.
Abstract:: The purification capacity of an activated sludge process is highly dependent of the rate of oxygen transfer from the air to the microorganisms. This rate can be increased in an air diffusion system by subjecting the culture to high shear and high pressure. A study of the effects of high...

Determination of equilibrium partial pressure of ammonia gas above anaerobically digested sewage sludge

Creator:: English, Charles Joseph
Abstract:: A laboratory study of anaerobically digested sewage sludge was performed to measure equilibrium constants for ammonia in the sludge. Measured constants describing the solution and dissociation of ammonia in sludge were compared to theoretical constants obtained from thermodynamic data. No significant difference was found between these two sets of constants....
