AWT and Conventional Mixed Liquor Settling Velocities
Publication: Environmental and Pipeline Engineering 2000
Abstract
Settling column analyses were performed on mixed liquor from seven AWT and two conventional wastewater treatment facilities. An algorithm was developed relating initial MLSS concentration and unstirred SVI (uSVI) of the mixed liquor to the zone settling velocity (Vs). Statistical analysis of the data using two-tailed paired comparison student-t tests indicated there was no significant difference between uSVI and stirred sludge volume index (sSVI). Examples are presented to illustrate how engineers and operators may utilize a secondary clarifier-operating diagram.
