Why Organic Residue Increases Biofilm Formation
ALVIM Biofilm Sensor
$90 $75
An early warning monitoring system for detecting bacterial biofilm growing in pipelines, tanks, machinery, etc.
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
