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 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...
