Mixed-Oxidant Electrolytic Disinfectant Generators (MEDGs)
Mixed-oxidant disinfectants are the preferred means of disinfecting ship’s potable water:
- Effective removal of biofilm in the distribution system.
- Treated water has no unpleasant taste.
- No bromine or other HazMat is used or produced. No operator exposure to HazMat. No bromine canisters to dispose of.
- Five-year typical cell life.
