UV-LED Antifouling lights
AML Oceanographic - Canada
What is UV Biofouling Control?
When instrumentation is deployed underwater in a stationary position for long periods of time, biofouling will occur.  This unwanted marine growth causes sensor drift, requiring preventative measures to ensure accurate data. Previously, the two most common methods to manage biofouling were mechanical wipers and chemical dosing. Neither is ideal, with the first being unsuitable for sensitive lenses and complex geometries, and the second being harmful to the environment.

AML’s biofouling control technology uses ultraviolet light to provide a non-toxic, non-contact solution to prevent marine growth.

A biofouling solution unlike any other method currently on the market, Streetlamp UV and Cabled UV prevent biofouling during long-term, in-situ deployments. The LED modules bathe critical surfaces in ultraviolet (UV) light, killing early growth to prevent biofouling, and thus eliminating environmental drift in CTDs and multi-parameter instruments, and keeping critical surfaces of subsea devices clean.
