IONTEC is an ion exchange system for water treatment, used for applications such as heating, cooling, and cleaning. Water hardness can cause limescale deposits in piping systems and process plants – IONTEC reduces this hardness through ion exchange .
 

 
 Application
 
 The IONTEC ion exchange system softens water used for purposes such as heating, cooling, and cleaning. Hard water causes limescale deposits in piping systems and process plants.
 

 
 How does ion exchange work?
 
 The system contains ion exchange resins :
 
 
 
 Insoluble, granular polymers – suitable for the respective application
 
 
 The resin contains positively ( cations ) or negatively ( anions ) bound ions.
 
 
 These ions are exchanged for ions from the water as the water flows through the system.
 
 

 
 Water softening (cation resin with Na⁺)
 
 A cation resin containing Na+ is used for water softening:
 
 
 
 Ca²⁺ and Mg²⁺ ions (hardness-causing minerals) are exchanged for Na+ ions from the resin.
 
 
 When the resin is "exhausted", a regeneration cycle is started.
 
 
 Regeneration is carried out with brine , during which Ca²⁺ and Mg²⁺ are removed from the resin.
 
 

 
 Demineralization (removal of dissolved ions)
 
 Demineralization essentially involves removing all dissolved ions from the water:
 
 
 
 Water flows through a cation resin with H+ (exchange of all cations)
 
 
 then an anion resin with OH- (exchange of all anions)
 
 
 H+ and OH- combine to form pure water.
 
 
 Regeneration:
 
 
 
 Cation resin: Regeneration with acid
 
 
 Anion resin: Regeneration with strong alkali. Resin type (depending on the version):
 
 
 in separate containers
 
 
 or together in one container ( mixed bed design ; on request)
 
 

 
 Typical role in the water treatment concept
 
 Ion exchange systems are often used as the first step in a more complex water treatment system.
