Understanding Cooling System Control Ranges and Critical Parameters

Cooling towers are a critical component in many water systems, providing comfort or process cooling across a broad spectrum of technologies and applications. Cooling towers vary greatly in design and footprint, but all have the main goal: to provide removal of waste heat from processes or building systems. Control parameters are critical to maintaining any cooling system to improve water and energy efficiency, maximize equipment life expectancy, reduce hazards, and minimize downtime.

How Microbiological Filters Work

Understanding the Basics of Microfiltration

How Microbiological Filters Work

Hospitals and healthcare facilities are becoming more aware of the dangers of waterborne pathogens that can exist in their manmade plumbing systems. With growing concern of preventing infections, point-of-use (POU) filtration has been more frequently used in the healthcare market to aid in reducing bacteria counts found in water. However, not all filters are created equally, and it is important to understand the basics of microbiological filtration.

My Building Water System Tested Positive for Legionella: Now What?

My Building Water System Tested Positive for Legionella: Now What?

We detected the presence of Legionella in one or more of our building water systems….. Now what do we do? This is probably the second most commonly asked question, surpassed only by:  “Do I have to test my water systems for Legionella?”  Often the question is posed this way:

“We recently performed Legionella testing on our building water systems and found one or more positive sample results.  What should we do about it?”

Ice Machines and Legionella

A Growing Problem

Ice Machines and Legionella

Each day people all over the world are exposed to ice. Whether it be from their refrigerator ice machine, their favorite restaurant, during their hospital stay, or on an airplane, people sip on their ice cold beverages or suck on ice chips unaware of the microorganisms that could be sitting dormant within the ice.

Legionella: To Sample, or Not To Sample?...That is the Question

What's required and what is my sampling plan?

Legionella: To Sample, or Not To Sample?...That is the Question

The simple answer is no (not directly), and here’s why:  There is no known safe level of Legionella in a building water system.  Therefore, even a non-detect sample result is not necessarily “safe.” The reason why is because the life cycle of this organism, coupled with the stresses put on it via temperature, disinfectants, etc. found within building water systems, may cause it to enter a viable but non-culturable (VBNC) state.
