Abstract

Removal of particulate COD by bioflocculation in the activated sludge process E. La ~ o t t a ' , J. ~irnknez~, D. ~arke3 & K. McManisl '~epartment of Civil and Environmental Engineering University of New Orleans, New Orleans, LA USA. '~rown and Caldwell, Inc., Walnut Creek, CA USA Abstract Most of the activated sludge models developed for the substrate removal kinetics have commonly assumed that the organic matter is dissolved, and do not include an identification of the fraction of the total COD (TCOD) that is truly dissolved (DCOD), nor the fraction that is particulate COD (PCOD). Recognizing that not all the COD in wastewater is dissolved, recent research efforts have concentrated on modeling the hydrolysis of particulate organic matter once it is trapped in the biological floc particles. However, little effort has been made in identifying how the particulate matter is actually removed form the liquid phase.
