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.
