Ion exchanger resins
New perspectives for water treatment
Ion exchanger resins are one of the most important tools for the treatment of aqueous solutions. Ever-increasing demands on the quality of water to be treated require ever more powerful ion exchangers and more efficient water treatment technologies. For 30 years BAYER/LANXESS has played a leading role in this regard.
The offering:
Powerful ion exchangers in combination with BAYER counterflow technologies such as fluidised-bed, lift-bed, rinse-bed and multistep.
