Controlling aerobic biological floc size using Couette-Taylor Bioreactors

Water Research, 147, 177–183.

By: J. Weaver* , H. Hong, J. Ducoste*  & F. de los Reyes* 

Contributors: J. Weaver* , H. Hong, J. Ducoste*  & F. Reyes* 

author keywords: Aerobic sludge; Floc size; Shear rate; Couette-taylor bioreactor
