Abstract
A portable digital optical camera-based system and method can be used to test water and coagulant samples in a chamber. The chamber has a substantially square shaped horizontal cross section and a least one see-through wall. The system and method can comprise a light source and a contrast plate that are configured to be manually placed, at least partially, into the water and coagulant samples through an aperture at the top of the chamber. The camera is configured to be located outside the chamber and to view an illuminated region in the chamber though the see-through wall. The system and method further comprise a mixing paddle that can be programmed to operate at different speeds during different time segments. The system and method can measure, store, and display time-series data of floc particle count, floc volume concentration, equivalent average spherical floc particle diameter, and computed average floc particle volume of the water and coagulant samples.
