Lewatit® MonoPlus MP 600 is a strongly basic, macroporous anion exchange resin (type II) with beads of uniform size (monodisperse) based 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 % (<0.350 mm) result in particularly low pressure losses compared with standard resins. Due to its special macroporous structure   

Lewatit®MonoPlus MP 600 stands for effective adsorption and desorption of naturally occuring organic substances. Due to the excellent regeneration efficiency and high operating capacity   

Lewatit®MonoPlus MP 600 is generally used for waters in which silica and carbon dioxide concentrations are moderate. For higher silica feeds, a type I anion exchange resin such as Lewatit® MonoPlus MP 800 is recommended.

Properties and benefits
Lewatit® MonoPlus MP 600 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 SP 112 or Lewatit® MonoPlus SP 112 (H)
»    working mixed bed in combination with Lewatit® MonoPlus SP 112 (H)

Lewatit® MonoPlus MP 600 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

During the application of type II anion exchange resins in the regenerated form the strongly basic groups are gradually converted to weakly basic ones. This process is an inherent property of the functional groups and enhanced by:

»    elevated oxygen concentrations ( e.g. downstream from a degassifier )
»    the presence of iron, maganese, copper, etc.
»    regeneration temperatures >25°C
»    operating temperatures >30°C
