The resultant pH after addition of the coagulant is the main criteria.
With aluminum sulfate, optimum coagulation efficiency and minimum floc solubility normally occur at pH 6.0 to 7.0. Iron coagulants can be used successfully over the much broader pH range of 5.0 to 11.0.
Jar test shall be used for selection and optimization of coagulant/poly-electrolyte.
