Chem-Aqua has invested in state-of-the-art research to develop chemical treatments capable of disrupting biofilms; contact us today to find out how to protect your facility from biofilm harm.
The most difficult challenge your cooling water system faces
Specifically in industrial water systems, biofilms are complex communities of surface attached bacteria growing inside a protective microbial secretion, often called slime. Recent research shows that biofilms are very difficult to remove from a system, as the bacteria underneath live in highly sophisticated communities that are capable of constantly adapting to become resistant to mechanical or chemical treatment.
Although biofilms start out microscopic in size, when the conditions become favourable, like process contaminations, they can grow into visible biofouling deposits in just a matter of DAYS!!!
Biofilms and their impact on cooling systems’ performances
Biofilms are much more insulating than calcium carbonate scale or iron oxide, which are traditionally recognised as problematic. For example, a mere 0.1mm layer of biofilm is four times more insulating than an equivalent coating of scale or iron oxide build-up, affecting heat transfer and significantly increasing operational and production costs. A 0.3mm biofilm layer (equivalent to the thickness of 3 A4 copy paper) is more than 5 times more isolating than scale!
System pipework and mission critical equipment in cooling systems like heat exchangers, chillers, etc. can be seriously damaged by the bacteria growing underneath and within the biofilm layer. The deterioration, called microbiological influenced corrosion (MIC), is up to 1,000 times more aggressive than normal corrosion decay and is accountable for up to 50 per cent of the total costs of corrosion prevention and treatment to the worldwide economy.
Chem-Aqua recognise that good results require a comprehensive programme of products, equipment and services that address the unique mechanical, operational and chemical requirements of your system.
The spread of Legionella pathogens
Biofilms are also the perfect safe hold for pathogens, like deadly Legionella.
Legionella pathogens breed under biofilm then travel and disperse, being released through water droplets into the atmosphere. They are protected by the biofilm and thrive within.
Chem-Aqua is registered with the Legionella Control Association (LCA); arrange a survey with us today to ensure you’re compliant with the latest legislation to keep your facility and staff protected.
Addressing the biofilm problem
Our New Science and Technology Group, working in close partnership with leading universities, have designed a new formulation able to unlock the complex matrix shield that gives the biofilm its incredible resistance. bioeXile® is up to 1250 times more efficient against biofilms than biocide alone and 278 times more efficient than biodispersants plus biocide.
Learning the Language of Microbiological Control
- Microorganisms are living organisms that require high magnification to see because they are so small.
- Bacteria are single cell microorganisms that require water, but not light, for normal grow.
- Aerobic bacteria require oxygen for growth. Many types of aerobic bacteria can form thick, sticky biofouling deposits that can block water flow, reduce heat transfer, increase pumping costs, cause corrosion and increase the potential for disease.
- Anaerobic bacteria require an absence of oxygen for growth. They can often be found growing underneath biofilms and biofouling deposits. Anaerobic bacteria, including Sulfate Reducing Bacteria (SRB), are a major cause of microbiologically influenced corrosion (MIC) in water systems.
- Protozoa are single cell microorganisms that can move independently and feed on biofilm associated bacteria and waste products. Amoebae are a type of protozoa. The presence of protozoa in a water system indicates advanced microbiological growth associated with biofilms.
- Legionella is a common waterborne bacteria that can cause a serious, sometimes fatal, illness called Legionnaires’ disease in exposed individuals. It is caused by inhaling aerosolised droplets of water containing an infectious amount of Legionella bacteria. It is characterised by fever, chills, lung congestion and severe pneumonia.
Understanding the cause of problems in water systems is the first step to solving them.Chem-Aqua provide custom designed water treatment programmes for your boiler, cooling and process water systems to ensure you don’t lose control of your water treatment.
