Lewatit® IN 42 is of lighter specific gravity than water and therefore it floats on the surface of ion exchange
resin bed.

as well as other packed bed systems.


Lewatit® IN 42 is of lighter specific gravity than water and therefore it floats on the surface of ion exchange
resin bed.


During service the upward flow (exception: Reverse WS-system) of the fluid to be treated forces the resin
bed against this layer. Thus, an uniformly distributed fluid passage through the resin bed is ensured. During
the regeneration phase the regenerant is evenly distributed by the downward flow. Besides, Lewatit® IN 42
protects the strainers of the discharge system from being clogged.
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,
