Description
This class addresses the complex challenges of managing corrosion, scale, and bacterial growth in drinking water systems. With increasing regulatory demands, utilities often face trade-offs between water quality, chemical usage, and compliance. We will explore innovative approaches to corrosion control that reduce reliance on phosphorus-based treatments, helping utilities meet evolving standards without compromising water quality or increasing phosphorus loads in wastewater influent.

Participants will learn about a novel equilibrium-blended phosphate solution that maintains water chemistry balance, optimizes corrosion control, and minimizes the formation of disinfection byproducts, all while lowering chemical costs. Through a live demonstration, we’ll examine corrosion processes, showcase how distribution system conditions affect treatment decisions, and discuss integrated strategies for improving chlorine stability, reducing lead and copper release, and meeting stringent regulatory limits. This session is ideal for water operators and professionals looking to enhance water quality management with sustainable, effective practices.
