This analysis was for both a tube and plate settler. Although tube settlers are used in the lab, plate settlers are used in the Honduras plants. Therefore, a model that takes into account the differences between the two apparatuses must be developed. With an accurate way to model floc roll up in a tube or plate settler, we can predict when floc roll up will happen given a set of conditions. This can help us optimize the plate settler spacing in order to prevent floc roll up from occuring.
