Lewatit® MonoPlus SP 112

Lewatit® MonoPlus SP 112 is a strongly acidic, macroporous cation exchange resin based on a styrene-divinylbenzene copolymer, in fully regenerated form (min.99% H +), designed for all demineralization applications. The resin is monodispersive and its 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 to standard resins.


Lewatit® MonoPlus SP 112 is especially suitable for:

  • Demineralization of water for industrial steam generation operated with co-current or modern counter-current systems like 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 MP 800 or Lewatit® MonoPlus MP 800 OH.
  • Condensate polishing in combination with Lewatit® MonoPlus MP 800 or Lewatit® MonoPlus MP 800 OH

Area of application

  • Demineralization of industrial water
  • Industrial Water Treatment
  • Mixed-bed
  • Condensate Polishing

Advantages of Lewatit® MonoPlus SP 112:

  • 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

CAS Number 

  • 69011 – 20 -7


  • Macroporous type Strongly Acid Cation exchange resin.
