FIGHT MACRO FOULING
COPRON is an anti-fouling system based on dosing of cuprous ions produced through ionisation of copper anodes [MGPS].
Copper is considered to be one of the three most toxic heavy metals for marine invertebrates. Copper limits reproduction, rapid growth and alteration of the composition of the organisms present in sea mud.
A COPRON system is usually formed of one or more copper anodes (for anti-fouling protection inside pipes), coupled with one or more aluminium anodes (to control corrosion of the pipes) or iron/stainless steel anodes (to control corrosion of the pipes and acting as cathodes), which are installed inside the sea water intakes or in the filters.
The anodes are connected to a direct current power supply that can be varied to allow controlled release of the copper ions (and aluminium or iron ones) and obtain the concentrations necessary for the biocidal action.
It is important to emphasise that use of copper as a biocide has been subject to international control for several years, as a potential marine pollutant, and its use in the waters of the European Union is governed through the ECHA, which authorises just a few companies to sell this type of system. ACG is listed in Art. 95 of the suppliers authorised to market biocides in accordance with Regulation (EU) no. 528/2012.
