Lewatit® MonoPlus MP 500 is a strongly basic, macroporous anion exchange resin (type I) with beads of uniform    size    (monodisperse)    based    on    a    styrene-divinylbenzene copolymer, designed for all demineralization applications.

The monodisperse beads have high chemical and osmotic stability. The extremely high monodispersity (uniformity coefficient: max. 1.1) and very low fines content of max. 0.1 % (< 0.315 mm) result in particularly low pressure losses compared with standard resins. Due to its special macroporous structure

Lewatit®MonoPlus MP 500 stands for effective adsorption and desorption of naturally occuring organic substances.

Properties and benefits
Lewatit® MonoPlus MP 500 is especially applicable for:

  • emineralization of water for industrial steam generation, e.g. Lewatit® WS System, Lewatit® Liftbed
  • System or Lewatit® Rinsebed System
  • polishing using the Lewatit® Multistep System or a conventional mixed bed arrangement in combination with  Lewatit® MonoPlus SP 112 or Lewatit® MonoPlus SP 112 H
  • condensate polishing in combination with Lewatit® MonoPlus SP 112 H

Lewatit® MonoPlus MP 500 adds special features to the resin bed:


  • high flow rates during regeneration and loading
  • good utilization of the total capacity
  • low rinse water requirement
  • homogeneous throughput of regenerants, water and solutions, resulting in a homogeneous operating zone
  • virtually linear pressure drop gradient across the entire bed depth, allowing operation with higher bed depths
  • good separation of the components in mixed bed applications
