It is an ultrasonic equipment designed to prevent the formation of marine biofouling. Prevents or reduces the growth of algae and other colonizing organisms in the hull and propellers of boats.
DUMO Marine ACM is a revolution in boat maintenance, as it is easy to install and easy to maintain. It is highly efficient against organisms that colonize the submerged part of vessels.
The pressure variations produced by the acoustic cavitation generated by ultrasound, create a stressful environment that prevents or reduces the settlement of colonizing organisms.
It is a preventive rather than reactive treatment. In general, ultrasound does not remove the specimens that have already been established but prevents them from settling.

There are more than 4,000 species that cause marine biofouling. Most of them live in shallow water areas on the coast, as well as in commercial ports and marinas, as these areas are rich in nutrients.
In general we differentiate between two main categories of marine biofouling: Microfouling (bacteria, diatoms,…) and Macrofouling (algae, barnacles, polychaete worms, bryozoans, hydrozoans, sponges,…).
There is a general pattern regarding the distribution of algae in the submerged part of a boat’s hull, determined by the different responses of the algae to the intensity and spectral composition of the light:
Under the algae, and also among them, there are diverse animals: hydroids, sedentary polychaetes, barnacles, molluscs and bryozoans. The bottom of the hulls is colonized by bryozoans, hydroids and barnacles.
