LEWATIT® MP 62

Lewatit® MP 62 is a weakly basic, macroporous anion exchange resin with tertiary amine groups (monofunctional), hence of particularly low basicity, and of standard bead size distribution. Its high total and operating capacity as well as the outstanding mechanical stability makes it unique for demineralization units, especially in combination with a strongly dissociated anion exchange resin if low silica leakage is required. Due to its macroporous structure Lewatit® MP 62 stands for effective adsorption and desorption of naturally occuring organic substances (high resistance to organic fouling).

Lewatit® MP 62 is especially suitable 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
• The removal of organic matter, especially from surface water
• The deacidification of organic process sreams

Note:
In order to avoid loss of active resin mass during backwash steps (due to the low density of 1.02 g/ml) we recommend to start first backwash step after at least 2-3 service runs which makes the loss of active resin mass less risky. Please make sure, that the linear velocity for the backwash step is at max. 3 m/h (100 % freeboard!).
