Abstract

Jar test is an essential procedure for the characterization of supply waters. The experimental conditions of a drinking-water treatment plant, as type and concentration of coagulant agent, rapid mixing time, slow mixing time, and decantation time are simulated in static reactors. About 90 results are necessary for the construction of the coagulation diagram which contains the iso-value curves. The aim of this work is to promote the optimization of the Jar Test procedure, reducing the quantity of assays by using the chemometric tool of experimental design, besides of the response surface methodology. The results expected are the reduction of time consumed and minimization of chemical waste generation.
