NRG Phoenix operates a large chilled water plant in downtown Phoenix serving multiple customers through a large chilled water system. Chilled water is produced at three separate facilities with a common chilled water loop. The facility switched from a traditional biocide program using stabilized bromine to a mixed oxidant solution (MOS) generated on-site using salt, water and electricity. Results from the program will be discussed (bacteria, algae, costs, safety) along with water chemistry.
