1. Introduction

The construction of a pH-ζ curve for wastewater, cationic PE, and anionic PE is the first step previous to selecting PE type and dose in a coagulation-flocculation process as those used in the semiconductor industry. This type of plot allows identifying the isoelectric point for each polyelectrolyte and wastewater.
