Lewatit® MonoPlus S 108 is a strongly acidic, gel-type cation exchange resin in the Na-form with beads of a uniform size (monodisperse) based on a styrene-divinylbenzene copolymer. This resin type is extremely resistant to chemical, osmotic and mechanical stress. That leads to very low leachables even under critical conditions like high temperatures, presence of oxidants (O2, Fe-oxides) and external regeneration processes. Even at very short cycle times (one cycle = service + regeneration) the special ion exchange resin matrix leads to long life cycles in demineralization processes. The high total capacity results in high operating capacities with a very low ionic leakage and a very high regenerant utilization. The extremely high monodispersity [uniformity coefficient: 1.05 (+/- 0.05)] and very low fines content of max 0.1% (<0.4 mm) results in particularly low pressure losses paired with an efficient and cost optimized operation of demineralization plants. Lewatit MonoPlus S 108 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 the following anion components: Lewatit MonoPlus M 500 MB, Lewatit MonoPlus M 800, Lewatit MonoPlus M 600, Lewatit MonoPlus MP 500, Lewatit MonoPlus MP 800 and Lewatit MonoPlus MP 600.
Lewatit MonoPlus S 108 adds special features to the resin bed:- high flow rates during regeneration and loading
- a high operating capacity at low regenerant consumption
- a low demand for rinse water
- a homogeneous throughput of regenerants, water and solutions, resulting in a homogeneous operation zone
- a virtually linear pressure drop gradient across the entire bed depth, allowing operation ith higher bed depths
- a low TOC emission and high resistance to oxidative stress
- a good separation of the components in mixed bed applications.
