Zeta Nanocera strategic alliance announced

Nanocera & Zeta logosJune 10, 2016
Tucson, Arizona —  Zeta Corporation and Nanocera are pleased to announce the formation of a strategic alliance co-marketing sustainable products and technical services to industry.  The two companies will combine development efforts in key industrial markets where customer productivity and sustainability interests overlap.  Principals at both companies have been interested in a collaboration for several years and look forward to promoting the alliance.

Nanocera offers leading edge, environmentally advantaged conversion coating technologies, which provide superior corrosion resistance and paint adhesion, eliminate damaging phosphates and regulated heavy metals, and significantly reduce total operating costs, including lower energy and water usage.

Zeta Corporation manufactures and markets Zeta Rod® systems, which significantly improve water and energy conservation, optimize the performance of industrial fluids, reduce water treatment chemical usage, and control scale and biological fouling in water systems.

DoD Corrosion Prevention and Control Program demonstrates 20% make-up water reduction and 50% reduction in blow-down utilizing Zeta Rod Water Management Systems

Link to USACE ERDC ReportThe U.S. Army Corps of Engineers Research Lab (USACE ERDC/CERL) has published data collected during a 24-month demonstration/validation project in which the  Zeta Rod® Water Management System was evaluated for its ability to deliver documented water conservation results while providing corrosion, scaling, and biofouling protection in open-loop evaporative cooling systems. The report, titled “Demonstration of Non-Corrosive, Capacitance-Based Water-Treatment Technology for Chilled Water Cooling Systems” evaluated sites at four military installations in Arizona, California, and Georgia.  The study included systems where the technology was previously installed as part of a 2010 evaluation (ERDC/CERL TR-09-20) and added systems that broadened the range of water qualities and operating conditions evaluated.

Results and observations indicated that the technology delivered an average 20% reduction in makeup water usage and 50% reduction in blow-down, while meeting or exceeding criteria for protection of equipment from scale, corrosion, and biofouling. Reductions in make-up water represent a major water savings for an installation, while reductions of blow-down water represent a significant lessening of load on installation’s wastewater treatment system. (The direct use of the blow-down water for grey-water purposes appears feasible, but was not demonstrated.)

The technology was effective in water treatment and deposit control for a wide range of water conditions, from very soft, corrosion-promoting water to very hard, scale-promoting water. The validated applications are recommended for consideration by decision makers to reduce military installation chemical utilization and support Department of Defense Net Zero Water goals.

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.

Cooling water conservation: What does 5.8 million gallons of water look like?

TVA Cooling Water Conservation Project: Zeta Rod Case Study

Imagine a swimming pool, roughly the size of a football field, five stories deep.  This is the volume of water (5.8 million gallons of water to be exact) that one U.S. Government Data Facility in the Southeastern United States has saved in one year by employing Zeta Rod® Water Management systems technology for its open loop water treatment and cooling water conservation program.  Most people are amazed to learn that a cooling tower system requires so much water to operate and that cooling water use generally eclipses all other facility water requirements.

The Tennessee Valley Authority (TVA) included a Zeta Rod Water Management system as part of an Energy Project for one of its major clients in the Southeastern United States. Results documented a 22% decrease in make up water, 65% decrease in wastewater, elimination of chemicals and an annual water savings of 5.8 million gallons.

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
