Membrane Filter Elements
Status: 06/2001/01 Operating Manual 47
The following maintenance work is required for exchangeable membrane filter element
types:
• Seals are wearing parts. Depending on their conditions of use, they must therefore be
checked at regular intervals, especially if leakage occurs.
Contamination must be removed during this inspection, and the seals may need to be
replaced.
• Screw connections can become loose. The tightening torque of the screws should be
checked regularly as part of general maintenance work and corrected as necessary in
order to avoid leakage.
• For the different types of membrane filter elements with exchangeable membranes, the
respective assembly manual can be obtained from LENSER.
• Check that all the functions of the filtering system are in order at regular intervals. You
must pay particular attention to checking those functions which indirectly ensure
operational reliability.
Consult the operating specifications of the filter press manufacturer for additional
information.
Monitoring operation
To achieve the longest possible service life of the filter elements and maximum operating
safety, we recommend continuously monitoring the main process parameters and
operating events and documenting them with the operating recorder or in system journals.
This is the only way to make sure that negative changes can be detected and rectified
immediately, particularly in periods of reduced supervision.
