Microbiological growth within a cooling water system if not controlled can result in the formation of biological fouling layers (biofilm) on all surfaces in contact with the water.
Biofilms pose serious risks, reduced operating efficiency, equipment failure via microbiologically influenced corrosion (MIC), and human health risks such as Legionnaire’s.
Modern Water’s ATP test is the first step in determining the effectiveness of a biocide treatment program and is an indicator of the extent and size of the biofilm. Microtox ATP analysis provides reliable test results in less than 15 minutes.
Anaerobic sulphate reducing bacteria (SRB) are ubiquitous in the environment and are commonly found in cooling waters. During their growth they are responsible for corrosion and pitting of metals/ concrete, fouling and the production of hydrogen sulphide.
Modern Water’s QuickChek SRB test kit is designed for both onsite and laboratory use and employs antibodies to specifically detect the enzyme adenosine-5’-phosphosulfonate (APS) reductase unique to all strains of SRB. Detects all viable and non-viable SRB in less than 10 minutes with the option of running two to three samples simultaneously. There are no interferences from chemicals or salinity.
Field-testing for SRB should be performed routinely. If results from the testing indicate SRB are present, corrective action, such as cleaning and disinfection, should be strongly considered. After cleaning and disinfection, the system must be monitored closely to determine if the cleaning measures were effective and to ensure SRB do not re-colonise the system.
The Modern Water ATP and SRB test kits used alone or in combination provide operators with economical, timely and trusted results, significantly reducing operational risks and operating costs.
