PHYSICAL ASPECT OF FLOCCULATION PROCESS .1. FUNDAMENTAL TREATISE

A dimensionless equation for the floc growth operation was developed and simulation of the floc growth operation was carried out to obtain the numerical solutions of the floc growth equation. A comparison of the simulation results with the experimental results suggested that it was necessary to introduce a collision-agglomeration function into the original floc growth equation. The floc growth equation with the collision-agglomeration function gave simulation results which almost coincided with the experimental results. The self-preserving nature of floc size distribution was found by using the results of both simulation and experiment. The results of simulation and experiment were shown in the normalized floc size distribution and the normalized removal rate in an ideal sedimentation basin. © 1979.
