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
Bacteria prefer to live in biofilms, which start out microscopic in size, but can grow into visible biofouling deposits in just a matter of DAYS. The biofilm structure protects bacteria from biocide additions, allowing them to form highly sophisticated communities that constantly adapt to become resistant to chemical treatments and mechanical removal.
Biofilms tend to form in hard to reach places. When conditions become unfavourable, they propagate by releasing bacteria into the bulk water to inhabit other surfaces. Multiple survival mechanisms make biofilms incredibly tenacious and difficult to control.
Should this be a concern? Yes!
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 4 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.
Biofilms promote the spread of Legionella pathogens
Biofilms also play a key role in the transmission of Legionnaires’ disease by providing a protective environment for Legionella bacteria to grow and multiply.

Addressing the biofilm problem
Biofilms are extraordinarily tenacious and difficult to remove. Effective control requires specialised expertise and technologies that address the unique challenges associated with biofilm control.
bioeXile works with biocide additions to remove biofilm far more effectively than using biocides alone or with conventional biodispersants.
Recognising the importance of good biofilm control, Chem-Aqua's New Science and Technology Group has developed new, patented, cutting edge technologies to help address key challenges for biofilm remediation and control.
bioDART Biofouling Monitor provides a sensitive, predictive indicator of the potential to form biofilm that can be used to gauge microbial control and provide an early warning of problems
Understanding the cause of problems in water systems is the first step to solving them. Chem-Aqua provides custom designed water treatment programmes for your water systems to ensure you don’t lose control of your water treatment.
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.
