Development of a Laboratory Clarifier Test to Predict Full Scale Primary Clarifier Performance
Peric, M.; Riffat, R.; Murthy, S.; Neupane, D. R. & Cassel, A.
Abstract
The objective of this research was to develop a laboratory test procedure to predict
full-scale primary clarifier performance using Chemically Enhanced primary Treatment (CEPT). A
method was developed that simulated actual primary clarifier performance, with chemical
enhancements, based on simulating full-scale surface overflow rate (SOR) and flocculation time in
the laboratory. The method used for this test was adapted from a procedure used for sizing of
Lamella Separators. Validation of the developed method was done by comparison of laboratory data,
with stress test data from two full-scale clarifiers, at the Blue Plains Advanced Wastewater Treatment
Plant in Washington, DC, USA. The results indicated that the laboratory SOR test method could be
calibrated to predict and optimize full-scale primary clarifier performance.
