A.3 Graphs
Diagram 1 Closing force for membrane filter elements size 470
Information
The following graphs (1 to 10) illustrate how to determine the closing force for 16 bar
standard membrane filter elements. The permissible, temperature-dependent operating
pressure is generally based on the squeezing pressure of the membranes. Only in
exceptional cases is the filtration pressure higher than the membrane squeezing
pressure.
The permissible pressures for filtration and washing the filter cakes can be found in
Graph 11 and 12.
The permissible squeezing pressure rise is shown in Graph 13 and 15.
Graphs 14 and 16 are used to determine the permissible squeezing pressure.
Operating pressure: p (bar)
Closing force: F (kN)
Temperature: T (°C)
