Importance of Biofilm Monitoring

What Standard Microbiological Tests Don’t Show

Importance of Biofilm Monitoring

Uncontrolled microbiological growth in cooling and process water systems is a multi-billion dollar problem for businesses each year. The primary cause of this expensive problem is biofilm. Biofilms form when bacteria and other microorganisms found in the bulk water attach to exposed surfaces and begin to produce a mass of biopolymers known as extracellular polymeric substance (EPS). The EPS provides a sticky, protective barrier that allows complex communities of bacteria to thrive and exponentially grow. Bulky, biofouling deposits can quickly form as the EPS traps dirt, corrosion byproducts, and other debris suspended in the water, leading to blockages.

Don't Let Biofilms Take Control of Your Cooling Tower System!

Biofilm deposits are one of the most difficult challenges your cooling water systems face. They tend to start in areas not accessible to biocide treatments, and can quickly grow to form biofouling deposits that can cause corrosion damage, blockages, reduced heat transfer, and amplify the growth of Legionella bacteria. Once they become established, biofilms are incredibly tenacious and difficult to remove.

Biofilm, Amoeba, and Legionella

Biofilms are the root cause of serious problems in building potable and industrial water systems including clogged piping, reduced heat transfer efficiency, microbiologically-influenced corrosion, and Legionella transmission. Biofilms are dynamic, complex structures optimized for microbial growth and survival, which make them difficult to remove and control.

Learning the Language of Microbiological Control

Water treatment specialists can forget that their clients may not understand the technical terms used in our industry. The language of microbiological control can be particularly confusing. To help establish a common working vocabulary, it’s important to define some key terms. Let’s get started!

Dead Legs, Biofilm, and Legionnaires Disease

Dead legs in building water systems can cause severe problems, including persistent positive Legionella test results and an increased incidence of Legionnaires’ disease. A basic understanding of dead legs, how to recognize them, and how to manage the problems they cause can help building owners reduce the risks associated with Legionella and other pathogens in their water systems.
