Ion exchangers

Ion exchangers for selective substance removal from wastewater and water

An ion exchange process is used when water needs to be treated for use in production or when substances, including valuable substances, need to be extracted from wastewater.

The filter material used in ion exchangers, ion exchange resin, is a special synthetic resin-based filter material with different functional groups. The main difference between the various ion exchange resins lies in the type of functional group.

Our water-treatment experts select the most appropriate ion exchange resins for your specific water treatment requirements.

Typical applications for the use of ion exchange resins

• Wastewater treatment with selective removal of dissolved substances (e.g. heavy metals)
• Recovery of valuable substances from wastewater
• Water softening and desalination
• Condensate cleaning (removal of alkalising agents and mineral salts)
• Hydrochloric acid cleaning
• Pickling bath cleaning (acid retardation)
• Cleaning solutions used in the production of sugar substitutes (e.g. sorbitol, xylitol)
