LEWATIT® MonoPlus S 108 H
Lewatit® MonoPlus S 108 H is a strongly acidic, gelular cation exchange resin with beads of uniform size (monodisperse) based an a styrene-divinylbenzene copolymer, in fully regenerated form. Due to a special manufacturing process this resin type is extremely resistant to chemical, osmotic and mechanical stress. That leads to very low leachables even under critical conditions like higher temperatures, presence of oxidants (02,
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 and very low fines content results in particularly low pressure losses paired with an efficient and cost optimized operation of demineralization plants.
Lewatit® MonoPlus S 108 H 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 H adds special features to the resin bed:
» 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 operating zone
» a virtually linear pressure drop gradient across the entire bed depth, allowing operation with higher bed depths
» a low TOC emission and high resistance to oxidative stress
» good separation of the components in mixed bed applications.
The special properties of this product can only be fully utilized if the technology and process used correspond to the current state-of-the-art. Further advice in this matter can be obtained from Lanxess Corporation.
