U.S. Government Releases Zeta Rod Cooling Water Conservation Study

Link to USACE ERDC SiteThe U.S. Army Corps of Engineers Construction Engineering Research Lab has published findings of a two-year Demonstration Validation Study that successfully compared Zeta Rod® Water Management Systems in side-by-side cooling tower installations against standard chemical water treatment programs.

The study, entitled “Demonstration of Electronic Capacitor-Based Water Treatment System for Application at Military Installations” presents the data and results of the study.

Abstract: The United States Department of Defense (DoD) has a specific legislative mandate to increase its conservation of water and energy. It also is interested in improving the effectiveness of open-loop, cooling water treatment processes at its installations worldwide, for purposes of extending the useful life of evaporative cooling equipment and reducing energy use/costs. A Cooperative Research and Development Agreement (CRADA) was approved to demonstrate that, without using chemical additives, a capacitor-based water treatment system is capable of (1) providing equivalent protection to a chemical treatment program in preventing scale, corrosion, and bio-fouling; (2) allowing cooling systems to be operated in an enhanced water conservation mode; (3) delivering measurable reductions in water usage over conventional methods; and (4) providing control, monitoring, and wireless data transfer via the Internet. Results documented in the subsequent demonstration and evaluation project showed the technology was able to meet every objective and also was able to deliver a 20% reduction in cooling water use over standard chemical treatment methods. Application of this technology would allow the DoD to (1) reduce chemical usage, exposure, and disposal expenses; (2) conserve water and energy; (3) facilitate water re-use; and (4) meet new goals for conservation of resources.

In making the announcement, Zeta President M. Michael Pitts, Jr, Ph.D. said that the City of Los Angeles Quality and Productivity Commission, after an eight-month evaluation process, singled out 20 city departments out of 114 applicants for honors in the categories of Customer Service, Environmental, Entrepreneurship, E-Business and Innovation and Creativity.

The Los Angeles Convention Center facilities staff won the Environmental Award for “the elimination of scale and corrosion cleaning, increased employee safety, reduced water consumption, longer equipment life and an annual savings of $50,000” in the operation of the huge building’s chillers and cooling towers.

Feasibility Study for EDR Wastewater Treatment & Recovery

“The Zeta Rod improved operability of the conventional RO treatment (relative to no pretreatment) although the mechanism responsible for the observed reduction in membrane fouling is not well understood. Feed pressures and WTC were more stable during Zeta Rod use at 50% recovery than without its use at 15% recovery.”

CH2M HILL

CH2M HILL, a global leader in full service engineering, construction and operations, was tasked to find a way to treat the concentrate stream from a water treatment plant located in Sherman, Texas USA. The City wanted to be able to treat this wastewater in order to reduce sewer and wastewater plant loadings, and to recover a portion of the wastewater as high quality water than could be used to increase plant finished water capacity.
