Hey, we can do that too...

As WCTI begins to capture more and more of the cooling tower treatment Market, with its innovative, patented sustainable natural green chemistry process in water conservation, the major's (left up to your own determination) are coming out with a "me too" approach. Where were the majors before WCTI began to eat into their market? Of course, some majors have had zero bleed approaches to water treatment, but frankly they were too expensive for most institutional markets (very low ROI) and still did not address the total discharge of solids from the process. Many still have to use sustained chemical feed to achieve this before, during or after the towers bleed. I call this their "designer" make-up and sewer treatment process. Oh, by the way, the revenue that they might lose on the lower water use, is made up in the equipment sold or chemicals used in their designer process.

Their process employs expensive "pretreatment" and "post bleed" equipment such as, HERO, lime softening, evaporation ponds etc... just to name a few, to achieve zero tower bleed conditions. Many have come out with questions and concerns to combat WCTI and its success that would make their own scientists blush and nervous. Most of these concerns that are designed to scare their own customers and prospects about WCTI's proven technology have been answered and or debunked in some cases by asking them to refer back to their own water handbooks for reference.

When I worked for one of these majors, I fought off the NCD (magnet) people for years on a regular basis and in just about every situation, won the argument by proving that NCD's (now pulsed power & hydrodynamic systems), have the same issues to deal with that chemical applications do. Usually, there was only limited success in one department or the other (i.e. corrosion, scale or microbio) and not all together without some addition of chemical to offset these concerns. At least chemical treatment allowed for addressing all concerns without the large expense that most NCD's warranted. Neither the NCD's nor the existing chemical programs could get the tower blowdown to less than 15% on a good day without a tremendous increase of OPEX and capital investment.

WCTI has now earned its stripes as the leader in water conservation for regular sources of municipal drinking water supply and well water. However, one argument that cannot be matched, is the ability of WCTI to take on "re-use"/"reclaim" water as a viable source for cooling tower make-up at a very high ROI.

WCTI’s Green Tech Conserves Water used in Large-scale Cooling Systems

by Robin Yeager on 10/17/2009 in Water

You gotta admire an entrepreneur who believes so keenly in the environmental benefits of his technology that he isn’t interested in selling out and risking the burial of his inventions and innovations by a corporate competitor.

Dan Duke, president of Water Conservation Technology International (WCTI), has patented a technology that eliminates “blowdown” (wastewater discharge) from cooling towers, which reduces the water required to run large-scale air conditioning systems by roughly 30%. This alone is enough to merit a Green Star award to WCTI. Another bonus of Duke’s system is that it doesn’t require toxic chemicals. Instead, key components are rock salt and recycled water.

If you aren’t familiar with cooling towers, you can find an explanation here. Also, a Boeing article explains Boeing’s success and savings with the WCTI process. See the “Boeing Frontiers” article near the bottom of the page.

WCTI licenses its patented cooling water scale and corrosion control technology, which typically reduces “20-50% of cooling tower blow down water wastage” resulting in tremendous amounts of water conserved, which benefits of all of us, and it reduces the cost of water and chemicals to the end user. The technology also utilizes “green” chemistry and controls corrosion, scale and biological performance. For more information, check out these papers, starting with the 2009 presentation on “Sustainable Natural Green Chemistry (NGC) for Cooling Towers”.

After the City of LA asked Jim Hardick, Craft Head for Steam Fitting & Refrigeration, to look into ways that the city can conserve water, Jim found out about WCTI’s technology. My thanks to Jim, whom I met at Southern California Edison’s 2009 Water Management Conference (see next post), as he invited me to join a small group who got to see the system up close and personal at a Honda North America building in Torrance. We also had the benefit of Dan Duke’s explanation of how his technology works and its benefits.

Honda is using its re-vamped cooling system as one of the elements in its goal of attaining LEED Platinum status for its Torrance facility. Let’s hope LA and other cities will consider WCTI’s green technology.
