Demineralisation

BWT ion exchange - designed and developed to improve your water quality

 

Demineralisation is a process by which inorganic salts, often referred to as Total Dissolved Solids (TDS), are removed from source water using a similar ion exchange process to the one found in water softeners. Total demineralisation of water can be obtained by mixing several types of ion exchange resin together - hence the name Mixed Bed. The vessel contains cation resin, which is strongly acidic, and anion resin, which is strongly alkaline.

 

When the water passes through the resin bed, the content of cation and anion in the water are exchanged for H+ and OH- respectively, which combined gives the result H20. Demineralised water contains hardly any cations and anions, therefore, the conductivity is very low, < 0.2 µS/cm. The content of silicic acid and free carbon dioxide are also significantly reduced, meaning minimal corrosion and scale deposits.
