Fortunately, reducing and controlling Legionella is relatively easy to do with an effective, continuous water treatment program that is regularly evaluated and maintained. The recently published ASHRAE Standard 188-2015 for managing Legionella risk outlines water treatment program guidelines for monitoring and reducing the bacteria in building water systems. It’s an excellent starting point for establishing or updating a water treatment program for your facility.
A central component of the standard is control measures to inactivate or kill pathogens as well as reduce scaling, corrosion, and biofilm in cooling towers and evaporative condensers. Control measures are also required for potable water systems, whirlpool spas, ornamental fountains, and aerosol generating misters, atomizers, air washers, and humidifiers.
There’s no single solution that is best for every application, but our filtration products can be valuable components of your water treatment program for managing Legionella risk in many new and retrofit situations.
Aqua-Stream™ High-Efficiency Side-Stream Filter
The Aqua-Stream filtration system has been proven to kill and control waterborne bacteria while removing suspended particles as small as 0.5 micrometers (microns). It provides continuous filtration and uses a small footprint, so it’s ideal as a water treatment product in retrofit and critical facility applications .
Pathex® Filter Media
Pathex antimicrobial filter media is the key to successful particle removal and controlling waterborne bacteria without the use of chemicals. (See our Technical Report, Breakthrough Filter Media Technology Kills Bacteria on Contact). Pathex is included in the Aqua-Stream filtration system and can also be used as a drop-in replacement for most sand and multi-media filters. Unlike plain sand filters that may harbor bacteria, Pathex kills waterborne bacteria on contact. Pathex is EPA registered as a pesticide and is NSF/ANSI Standard 61 certified for drinking water system components.
