General Details

Real-time, online, continuous biofilm monitoring

Bacteria can colonize in structures in contact with water, like pipelines, tanks, machinery, etc., in a very short time if appropriate countermeasures are not applied.

The ALVIM sensor is able to detect bacterial settlement from the moment microbial attachment starts (down to 1% of surface covered by microorganisms). Real-time data is used to make decisions on when to apply biofilm removal enzymes, and to manually or automatically adjust and optimize cleaning treatments or biocide treatments.

Advantages of this technology

  • Early warning detection of bacterial biofilm development
  • While fouling sensors detect “generic deposit”, ALVIM probes detect bacterial biofilm
  • Optimization of cleaning and sanitation treatments
  • Easy to install, easy to operate
  • Virtually maintenance-free probe
  • Real-time, continuous biofilm monitoring
  • High sensitivity
  • Modular, scalable system

Did you miss the Biofilm Summit 2020? Here’s a recap…

Biofilms form the largest activity center on the planet. Contamination, fouling and energy loss from biofilms is costing the food industry billions in world GDP, while claiming the lives of millions worldwide. Recently we had the pleasure of attending the Barcelona Biofilm Summit 2020 held online. It was extremely interesting and informative, and for those […]

Zero tolerance for Listeria means zero tolerance for biofilms!

Anyone working in the food processing industry will know how a biofilm left undetected and untreated can cause havoc. Outbreaks of large scale contamination start with biofilm-forming bacteria. Listeria are amongst the most enthusiastic of these biofilm formers. Listeria monocytogenes, is a foodborne pathogen responsible for the Listeriosis illness. It is able to rapidly adhere […]

How to fight biofilms in pipes and tanks

Did you know that most bacteria in pipes and tanks live in biofilms and not free in the water? And, while free floating bacteria is easy to remove, biofilms are not. Unfortunately pipes and tanks make an ideal environment for pathogenic and spoilage bacteria to thrive in biofilm. This is where you may find some […]
