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.

  • Model 9130 MEDG

    $0.00
    • Designed to be capable of disinfecting two sources of water simultaneously using an injection process, with minimal operator attention.
    • Electrically operated, package-type (bulkhead-mounted) unit ready for operation (turn-key system) with a footprint of 48 inches wide x 12 inches deep x 48 inches high.
    • Uses granular or pellet salt (sodium chloride) and potable water as inputs to produce a concentrated disinfectant solution in an electrolytic cell. The disinfectant solution is metered into the discharge from the ship’s desalination plants as an initial disinfectant and/or metered into recirculated water from the ship’s potable water tanks to replenish the level of disinfectant in the tanks.
