Reduce Legionella Risk With Quality Water Treatment

Reduce Legionella Risk with Quality Water Treatment


A Water Quality Products article of March 2013 details out the risk of hard water scale and bio film in Cooling Towers as well as other equipment.  How these can contribute to the presence of Legionella bacterium and lead to Legionnaires’ disease via the inhalation of contaminated water.

Watch the following video to learn more:


Anywhere water runs, it can deposit calcium as limescale…even a dripping sink! The article rightly states:

“Scale, or limescale, is a hard, rock-like deposit of calcium or magnesium salts that forms in heat exchangers, cooling tower packing and other water-fed equipment as a result of heat and increased concentration factor. Scale formation impairs heat transfer, interferes with flow and cooling, and can be a breeding ground for Legionella.

The scaling tendency of a water supply depends on the hardness of the water; still, if not adequately treated, even relatively soft waters can become highly scaling when concentrated by evaporation. Poor scale control not only puts the cooling process at risk, but also can squander thousands of dollars in wasted energy, chemical and water charges.

Scale is a problem in both hot- and cold-water systems. Dripping taps can deposit scale in and around the tap, and with high ambient room temperatures provide an ideal growth medium for L. pneumophila. In hot water systems, scale can trap Legionella and biofilm, providing a perfect growth medium that disinfectants cannot penetrate.

Scale deposits colonized by Legionella can continuously re-contaminate a system even after disinfection.”

Making large changes like Cooling Tower treatment can take months or years to get approved.  Plus, how do you know the technology you are switching to is going to work with your water?  Here’s one answer you might like…We have hundreds of units in Healthcare Facilities across the USA.  Some applications include, but are not limited to:

  • Mercy Healthcare – ice machines – Missouri
  • Unity Point Healthcare – ice machines
  • Merck – ice machines – Missouri
  • Wesley Medical – ice machines – Kansas
  • Port Huron Medical – ice machines, dishwashers, humidifiers, water heaters – Port Huron, Michigan
  • Hays Medical – ice machines – Hays, Kansas
  • Trego Medical – ice machines, water main main, hot water re-circ – Wakeeney, Kansas
  • Brookdale – water mains, hot water re-circ – Brentwood, Tennessee and other states
  • Lake Regional – cooling tower, ice machines, steamers, humidifiers – Osage Beach, Missouri
  • Sharp Memorial – large heat exchanger – San Diego, California

So why not try out a proven Non Chemical Water Treatment in an Ice Machine?  Lots of other Healthcare Facilities are already enjoying the benefits of reduced maintenance and safer equipment, so should you.


It’s time to show you what we can do for your facility.  Most commercial Ice Machines can be protected from scale with just one of our 3/8″ Scaletron units.  Our units are simple to install and dramatic results are typically seen in just a few weeks.

We are so confident that we can help solve your scale problems, we would like to send you a unit for one of YOUR Ice Machines at NO COST today!

Click and Submit your Request for a No Cost Demo and we will have it on the way within 24 hours.

To date we are the only Non Chemical Water Treatment that the U.S. General Services Administration (GSA) has studied and proved out as part of the Green Proving Ground (GPG) program.
