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 occurring 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 deacidificaiton of organic process streams
Note: In order to avoid loss of active resin mass during backwash steps (due to the low density of 1.02 g/ml) Lanxess recommends to start first backwash step after at least 2-3 service runs which makes the loss of active resin mass less risky. Ensure that the linear velocity for the backwash step is at max. 3 m/h (100% freeboard!)Information provided by Lanxess. |
