Biofilm Monitoring System
Early Detection of Bacterial Growth on Surfaces
Page last modified
August 4 2023
The ALVIM real-time, online, Biofilm Monitoring System is able to detect bacterial settlement since its first phases (down to 1% of surface covered by microorganisms). Basing on ALVIM data it is possible to adjust and optimize water treatments / biocide treatments, verifying, at the same time, the efficacy of the sanitation. ALVIM Biofilm Sensors are used worldwide in many different fields, ranging from industrial cooling waters to Food and Beverage, Pulp and Paper, Oil and Gas and others, including many Fortune 500 Companies.
Pro/con
Early warning detection of bacterial biofilm growing on pipelines, tanks, heat exchangers and RO membranes
While fouling sensors detect "generic deposit", ALVIM probes detect bacterial biofilm
Optimisation of cleaning and sanitation treatments (biocides, disinfectants)
Easy to install and operate, virtually maintenance-free probe
Real-time, continuous biofilm monitoring system with high sensitivity, modularity and scalability
Cannot work at low concentrations of oxygen (<1 ppm) and low conductivity (<10 microS/cm)
