Alternative Water Treatment Technologies for Cooling Tower Applications

The current state of water treatment in GSA buildings is to use conventional chemical maintenance for water quality and contract out this specialized service, for a fixed fee, to a third-party company specializing in such service. Traditional water treatment approaches rely on chemicals to extend the ability of the water to hold scaling minerals in suspension and kill off biological growth. This project assesses the effectiveness of three different technologies provided by three different manufacturers. Each system uses some sort of proprietary device, technology, or chemical. This report addresses both water and cost savings associated with Alternative Water Treatment (AWT) technologies, and the water quality provided by the AWT technologies.
