The layer of bacteria (biofilm) that forms on surfaces in contact with water and other liquids is a major problem in many industrial applications. Indeed, it causes several issues:
- microbial corrosion (MIC);
- decreased efficiency of heat exchangers (loss of 30% and more);
- proliferation of pathogens (90% of bacteria live in biofilms);
ALVIM Biofilm Sensor detects bacterial settlement since its first phases and, based on these data, to manually or automatically adjust and optimize biocide / sanitation treatments allowing to check, at the same time, the efficacy of the cleaning.

Benefits

• Detects bacterial growth on surfaces (not general deposit) inside pipelines and tanks
• Real time monitoring
• Allows to optimize cleaning/sanitation treatments, with a proactive approach
• Long lifetime (5 years and more)
• No calibration needed

Temperature: from -10 ° C to + 120 ° C (for monitoring microbiota growth, a temperature of + 2 ° C to + 40 ° C is required);
Oxygen: 1 ppm (0.0001%) or more;
Electrical conductivity:> 10 μS / cm;
Constant current source: 12V ± 20%, 150mA;
Data transmission: via MODBUS RTU protocol, RS485 standard, current 4-20 mA;
Required Wiring: Standard six-core cable (FROR 6x0.5 preferred);
Operating system: Windows XP or higher
