Sample calculation of the final chamber filling
A mixed plate pack consisting of membrane filter elements KME bloc PP and chamber
filter elements KXE has a resulting chamber depth of 50 mm.
The final cake thickness after squeezing is to be at least 60 %:
60 % of 50 mm = 30 mm
Note
If the minimum cake thickness is not achieved, please contact LENSER.
The recommended limits of the final cake thickness after squeezing are based on the
experience of the industrial users of our membrane filter elements. In special cases it
may be advisable to change these limits.
