Program description:
Chromate is a potent carcinogen found in many potable water supplies at concentrations sufficient to require treatment. Options for treatment include both precipitation and ion exchange methods. In this workshop we will review the options and chemistry of both treatment methods including chemistry and chemical feed requirements, sizing, equipment footprints, labor, and changes in water composition resulting from treatment.

The workshop will also review several case histories for chromate treatment systems that are in operation that have switched from one form of treatment to another and the rationale behind changing methods.
