Reverse-osmosis desalination plant of ПРО-0,25 type

Reverse-osmosis desalination plant of ПРО-0,25 type is designed for production of potable water from sea water aboard a ship. Desalination is based on the reverse osmosis principle that is forcing salt water under high pressure through semipermeable membrane.

The plant consists of separately arranged units:

  • desalination unit;
  • pump unit;
  • boron-selective filter;
  • control board.
