PURPOSE

Reverse-osmosis desalination plant ПРО is designed for production of potable water from sea water aboard ships. Desalination is based on the reverse osmosis principle that is forcing salt water under high pressure through semipermeable membrane.

DESIGN

The plant consists of the following units:

  • desalination unit;
  • pump unit;
  • control board.
