Salt-Based and Chemical Inhibition for Cooling Towers

Three different alternative water treatments (AWTs) were evaluated at the Denver Federal Center by the National Renewable Energy Laboratory (NREL). Two out of the three were found to:

• Maintain adequate water quality.

• Lower water and sewer costs.

• Improve chiller operations.
