Zeta Library Collections: FAQ's

What is a Zeta Rod® System for Home Water Conditioning, and is it affordable? The Zeta Rod® green technology offers a highly economical and environmentally sound method of water conditioning that uses the physical and electrochemical effects of electrostatic fields to disperse bacteria and nano-crystals that form biofilm and scale. A Zeta Rod system will normally pay for itself in chemical savings (salts), water conservation (no back-flushing) and maintenance over a period of months rather than years.

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.
