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.

Chlorine and Bromine Testing In Cooling Tower Systems

Chlorine and bromine based biocides are widely used for microbiological control in cooling tower systems. These halogen compounds form strong oxidizing agents in water, which is how they kill bacteria and other microorganisms. Routine testing is important to confirm effective halogen residuals are maintained. Low residuals can result in poor microbiological control. High residuals can cause corrosion and destroy inhibitors.

How Blended Water Supplies Impact Water Treatment

Not All Water Supplies are the Same

The source(s) of water supplied to cooling towers, boilers, and processes may vary greatly daily or even hourly.  The impact this has on water systems must be closely monitored to avoid scale, deposits, corrosion, inefficient water usage, and other negative impacts on operational costs.

How Often Should I Test My Water?

Chem-Aqua representatives are frequently asked, “How often do I need to test my water?”  The answer to this question is as varied as the systems that Chem-Aqua treats.  There are a number of factors that go into determining the “best practice” for each facility.  Typically, these factors are:

How to Keep Your Cooling Tower Clean

Cottonseed and Other Spring Associated Problems:

Every spring we welcome the milder weather, and with it, various plant and animal life. However, not all of nature’s gifts are beneficial to our evaporative cooling systems; especially the outdoor cooling towers that reject heat from our commercial, institutional, and industrial facilities. Late wintry storms can cause ice and snow accumulation. Heavy rain and hail can disrupt the anticipated easing of the harsh environmental conditions of winter.
