Concept
Ion exchange is a separation process for the removal of dissolved impurities by using gel type or macroporous resins. Typically strong acidic cation exchange and weak or strong basic anion exchange resins are used.
Ion exchange
Applications
In bioprocessing it is employed upstream to treat raw materials for biological processing requirements, and downstream to purify and de-colorize the final product to comply with commercial specifications.
Vogelbusch know-how covers the embedding of ion exchange into the overall process in fixed bed reactors with co- or counter-current regeneration, including the selection of cation and anion exchange resins and automation for continuous operation. Eco-friendly design of regeneration procedures minimizes fresh water and chemical consumption and product losses.
Application in Technologies
„Based on the reconstruction according to the consulting by Vogelbusch, the rectification plant now shows fully satisfactory fine alcohol quality yield and performance."Dr. Wilkening, KWST, Rectification Unit, Hannover, Germany
