Desalination plants

Water treatment / Desalination

Desalination systems for everything from kitchens to oil rigs

In a water softening system such as Guldagers UniSoft system, lime and magnesium salts are removed from the water. However, there will still be mineral salts left in the water, which can cause problems for dishwashing in a commercial kitchen or for technical installations.

Guldager supplies desalination systems for everything from kitchens to large industrial installations.

Guldager's desalination plant uses reverse osmosis, which is a membrane separation process that allows water molecules to pass through but retains most of the salt content.

The membranes in Guldager reverse osmosis systems retain 95 - 98% of all salts.

The systems are available in several sizes and cover all needs from small laboratories to large desalination plants for large industrial installations.
