Veterans’ Hospital in the Southwest

Equipment Description:

A point-of-entry High-Capacity Ultrafiltration system installed on the city water feed to the hospital. The system includes duplex bag filter housings in a parallel installation for large particulate removal, Phoenix GT-3 system capable of filtering down to 0.01 microns, removing virtually all sediment and pathogens, two flow-through-style bladder tanks, and a UV lamp assembly.

Problem:

A new hospital facility was being constructed with an engineer who recognized that there are means and methods available to help design a system to virtually eliminate Legionella from growing in or being distributed by the plumbing system. This difficult challenge was accepted by the engineers to help reduce the risk of spreading Legionnaires’ disease to the patients of the facility, who often have compromised immune systems, making them more vulnerable to these harmful pathogens.

Solution:

Installation of a High-Capacity Ultrafiltration system at the point of entry with the initial fill and ongoing water supply run through the HUF system. This approach creates a firewall at the point of entry, protecting the plumbing system from contamination by harmful pathogens and helping to prevent the formation and expansion of biofilm throughout the plumbing system.
