Development of a jar testing protocol for chemical phosphorus removal
During the jar tests, the most favourable stirrer shear for ferrous sulphate, aluminium sulphate and both of the VTA chemicals was 237 s −1. This value was slightly higher for ferric chloride, 411 s −1. Although these values are both within the reported range, perhaps a better guide would be comparing the Camp number.
