Lewatit® MonoPlus M 500 OH is a strongly basic, gelular anion exchange resin (type I) with beads of uniform size (monodisperse) base 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. Lewatit MonoPlus M 500 OH is especially applicable for:- the 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 conventional mixed bed arrangement in combination with Lewatit MonoPlus S 108 H or Lewatit MonoPlus S 200 KR.
Lewatit MonoPlus M 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 homogenous 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
