The EcoGuardian system consists of filtration with electrolysis treatment at uptake and neutralisation during discharge. The approval covers models with maximum treatment rated capacities between 130 m3/h and 4,000 m3/h. it can operate in all salinities and in water temperatures between 0 and 40°C. When necessary the Electrolyte Feed Salinity must be greater than 10PSU and temperature above 10°C.

The system may not be installed on a US flag vessel but may be installed in hazardous locations to which it is certified on a foreign flag vessel subject to approval of the foreign administration.
