Simulation of plant flocculators can be accomplished by using jar testing equipment. Similar conditions should be maintained between laboratory and full‐scale work. In this article several G curves for jar testing are presented that allow different small‐scale geometries to be used. Power curves were also developed and correlated to power numbers available in the literature for large impellers. Subsequently, a procedure is presented for determining the full‐scale G values.
