Arizona, one of the hottest states in the country and home to the Sonoran Desert has been known for its desert climate, with hot summers and mild winters. Like other deserts, availability of water is scarce. The largest city in Arizona, Phoenix sits atop a large water aquifer and have no water issues but, the rest of the state has a different story to tell. The Colorado River is half-full, Lake Powell is half-empty, Lake Mead has shrunk to its lowest level and the reservoirs of Roosevelt Lake and the Salt and Verde rivers are dwindling. To compound to this issue, if the Colorado River is declared in a shortage, Arizona could face its first water-supply cut.

The possible silver lining in these dense water issues is that the per capita demand for water in major cities have decreased. Still, households in some areas use far more water than the average Arizona resident, at 100 gallons per day. Much of this reduction in water usage has been attributed to conservation efforts started by the state in as early as 1980. Since then, four Management Plans have been designed and executed. The discussion about water conservation is prominent in each one of them and the Second Management Plan defines water use limits for cooling towers with a load above 250 nominal tons. During the third plan, the limits were extended to any cooling facility with a total cooling capacity of at least 1,000 tons. It was recommended to manage and maintain operating efficiency while minimizing wastewater for disposal.

The make-up water conductivity in most cities in Arizona range drastically between 500 µS and 1,100 µS.Most chemical water treatment companies are left baffled with this huge swing in incoming conductivity and struggle to maintain high cycles of concentration. Cycles of concentration is measure of the amount of salts in your basin to that in the make-up water. The greater this ratio, the greater are your water savings. Companies that add chemicals to water tend to fight against the nature of water at higher pH to precipitate the salts as scale. Chemical treatment tries to restrict this tendency of water to remove excess salts by lowering the pH closer to neutral. While, this is effective to some extent, the limitations far outweigh the advantages. Most traditional chemical treatment systems do not treat water above 2,500 µS. What this means to customers in states like Arizona is: you cannot maintain over 2.5 cycles at a make-up conductivity of 1,100 µS.

Trying to fight nature is an uphill climb that is sure to fail. We at Dynamic Water Technologies partner with innovative non-chemical water treatment technologies like Universal Environmental Technologies (UET) and Powell Water to provide Arizona with the best water treatment systems. The UET cooling tower system ensures that the salts that tend to scale in your cooling tower do so within our reactor. It does so by the process of partial electrolysis. The reactor through electrolysis accelerates scaling within the reactor and generates a potent biocide. This ensures minimal scaling and reduced biologics in your towers.

Please contact us should you have a more questions on the process and how it can be employed for your system. We guarantee that we can design a system to meet any requirement.
