Lewatit® MonoPlus MP 500 OH is a strongly basic, macroporous anion exchange resin (type I) with beads of uniform size (monodisperse) based on a styrene-divinylbenzene copolymer, in highly regenerated form (min. 80% OH-), designed for all polishing 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.  Lewatit® MonoPlus MP 500 OH stands for effective adsorption and desorption of naturally occuring organic substances.

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

»    polishing using the Lewatit® Multistep System or a conventional mixed bed arrangement in combination with  Lewatit® MonoPlus SP 112 H or Lewatit® MonoPlus S 100 H
»    condensate polishing in combination with Lewatit® MonoPlus SP 112 H or Lewatit® MonoPlus S 200 KR
»    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

Lewatit® MonoPlus MP 500 OH 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
