High NWP in Millipore Sigma Water Filtration Systems can be caused by damage to the membrane or cassette, requiring an integrity test of the cassette. It may also be due to the system and cassette being over-pressurized, in which case you should reduce the system pressure. Another reason could be a worn cassette, which would necessitate its replacement.
What to do if there are tube fitting leaks in Millipore Sigma Pellicon 3 Cassettes?
If you notice tube fitting leaks in your Millipore Sigma Water Filtration Systems, several factors could be responsible. The tube or fitting might be cracked, necessitating inspection and replacement of the part. An NPT fitting might not be properly wrapped; in this case, remove the old tape and re-tape adequately with PTFE tape. The end of the tubing might not be cut squarely, requiring you to cut the tube square and reinstall it. A missing O-ring or ferrule on the fittings or a defective sanitary gasket could also be the cause, so replace the missing component, gasket, or the entire fitting. A loose clamp simply needs tightening, while an oversized clamp should be replaced with a smaller diameter clamp.
Why is there a leak between the holder and filters in my Millipore Sigma Pellicon 3 Cassettes?
If you observe a leak between the holder and filters in your Millipore Sigma Water Filtration Systems, it could be due to dirt or debris in the filter. To resolve this, disassemble the stack and check for any debris. Another potential cause is compression force being too low, in which case you should check the torque and compressive force.
