ABSTRACT
INTRODUCTION

  • Calculating the minimum effective dosage.

  • Calculating the dissociation profile for an inhibitor and its impact upon scale inhibitor active species.

  • Determining the upper driving force limit for the inhibitor, beyond which even very high dosages do not provide scale control.

  • Determining if an upper limits exists for cations, such as the solubility of calcium phosphonates.

  • Determining if the inhibitor ”salts out” at high ionic strength.

  • Determining if separate mechanisms are operative for low and high saturation environments, requiring separate models.
