Abstract:  Zeta Rod® Water Management Systems were select­ed to be uti­lized as the water treat­ment sys­tem of choice for the recir­cu­lat­ing open-loop chillers, heat exchang­ers and cool­ing tow­ers for the two HVAC Central Plants at a U.S. Government Data Facility in the Southeastern United States. The pur­pose of the sys­tem was to deliv­er sig­nif­i­cant water con­ser­va­tion while pro­tect­ing crit­i­cal cool­ing equip­ment in a man­ner con­sis­tent with a well man­aged tra­di­tion­al chem­i­cal water treat­ment pro­gram. The Zeta Rod sys­tem was includ­ed as part of an Energy & Water Conservation Project imple­ment­ed by the Tennessee Valley Authority (TVA).
