TVA Cooling Water Conservation Project

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).

  • 22% less make up water used
  • 65% less waste water sent to the sew­er
  • 5.8 Million gal­lons of water saved dur­ing the first year

City of Tucson Crime Lab: Enhanced Water Conservation, Chemistry Reduction and Re-Use Opportunities for Open Loop HVAC Water Treatment

The appli­ca­tion of a Zeta Rod Water Management pro­gram allowed the Crime Lab to earn the LEED point under Water Efficiency and Innovation in Design. In par­tic­u­lar, a mea­sur­able non-reg­u­lat­ed water use sav­ings that is at least 10% of the total cal­cu­lat­ed base­line design (166,000 gal­lons for the Crime Lab) for reg­u­lat­ed (fix­tures) water use is eli­gi­ble for an exem­plary per­for­mance ID point under WE Credit 3.  This project con­ser­v­a­tive­ly doc­u­ment­ed sav­ings of  674% of the base­line cal­cu­la­tion for an annu­al total of 1.1 mil­lion gal­lons.

Within 60 days, results deliv­ered by the Zeta Rods were sig­nif­i­cant:

• Reduced water con­sump­tion per vehi­cle from 48.75 gal­lons per car (gpc) to 35.51 gpc; a net reduc­tion of 27% per vehi­cle
• 235,000 gal­lons of water saved in 60 days
• 38% drop in the total per vehi­cle wash­ing cost

BP Manufacturing Solutions Reduces Chemical and Filtration Costs at GMPT Flint, Michigan USA

BP Manufacturing Solutions reduces chem­i­cal and fil­tra­tion costs, GMPT Flint, Michigan USA

Highlights: Several pos­i­tive out­comes result­ed from the use of Zeta Rods. Because fun­gal growth in the high-pres­sure tanks was elim­i­nat­ed, pro­duc­tion down­time was min­i­mized. The fun­gal reduc­tion reduced main­te­nance costs and improved oper­a­tional effi­cien­cies. Chemical usage also dropped, most notably in anti-foam due to the change in sur­face ten­sion caused by Zeta RodsTM. This anit-foam reduc­tion alone pro­vid­ed an annu­al cost sav­ings of $120,000.
