CORROSION BIOCORROSION BIOFOULING TESTS

Accelerated corrosion A unique know-how After many years of in-house research & development projects, Corrodys is now able to recreate in the laboratory accelerated MIC (Microbiologically Influenced Corrosion)

Formation of pathogenic biofilms just after 4 weeks (in a marine environment) Quick answers guaranteed Observation of samples from accelerated biocorrosion test after 15 days

Without biocide

With biocide


CORROSION BIOCORROSION BIOFOULING TESTS

Test loop in renewed environment OBJECTIVES Evaluate biocides effectiveness (antimicrobial, inhibitors…) on biofilms Assess the safety of those products on the materials

Help development of innovative environmentally friendly solutions
