Aggregates Settling Velocity‐Direct In Situ Measurement

Abstract

Settling velocity and size of aggregates were observed by the method where the aggregates were illuminated by light sheet (plane) and their movement and size were evaluated from image analyses of obtained images. The main aim was to measure settling velocities of aggregates in situ. The used model system was an agitated vessel where the aggregation process took place. Such determined settling velocity could advantageously serve as a complex parameter for scale up of separation equipment.
