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.

Zeta Rod® Systems Receive IAPMO Certification

Uniform Plumbing Code NSF61 Logo

February 8, 2006

Tucson, Arizona — Zeta Corporation is pleased to announce that its patent­ed Zeta Rod® Systems have received IAPMO Research &Testing cer­ti­fi­ca­tion and will now bear the UPCNSF/ ANSI 61 mark, indi­cat­ing that they con­form to the stan­dards for Drinking Water Systems Components – Health Effects, as well as to the plumb­ing and elec­tri­cal require­ments set forth in the Uniform Plumbing CodeTM Interim Guide Criteria 91–2005a. Although the prod­ucts had pre­vi­ous­ly been ETL list­ed to NSF-61, the asso­ci­a­tion with IAPMO broad­ens the scope of the cer­ti­fi­ca­tion to include addi­tion­al plumb­ing and elec­tri­cal safe­ty stan­dards devel­oped specif­i­cal­ly for the patent­ed Zeta tech­nol­o­gy.

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, 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.
