The Zeta Library is organized as a digital post catalog; each post containing a specific piece of content. The Collections area located in the sidebar (or below on mobile devices) will allow you to filter the content for the information you are seeking. You may also search our entire site content by Applications, Markets, Benefits and other categories listed. Library Posts will post a short description and link to the corresponding document or media file. The Zeta Library is in the building stage and more documents are added daily. Can’t find what you’re looking for? Give us a call at 888−785−9660 or contact us via email and we will be glad to help!
20% reductions in cooling tower make-up water and 50% reduction in blow-down were achieved at four U.S. Military Bases over a 24 month study period.
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.
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

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.
