Watermaker for Offshore Applications


Our standard seawater RO systems for offshore applications are fully self-contained with production capacities from 8,000 to 26,500 GPD. Features of our standard systems are:

  • A membrane flux rate below 10 GFD to extend membrane life and minimize fouling.
  • Reciprocating pumps with nickel aluminum bronze fluid end; sized at no more than 65% of the maximum rated RPM.
  • Suction and discharge pulsation dampeners (non-corrosive) or a non-pulsating type pump (depending on capacity).
  • Dual or triplex multi-media filtration sized for manual backwash of one while continuing system operation.
  • Cartridge filtration
  • Automatic inlet feed valve
  • Automatic feed water flush on startup
  • Automatic product water flush on shutdown.
  • Conductivity monitor/controller driven product diverter valve to dump unacceptable water.
  • Permanently piped membrane cleaning system.
  • PLC driven control panel
  • Non-cavitating type reject choke valve, 316L S.S. w/TC
  • Passivation treatment of all welded 316L S.S. piping
