xbymcWe mentioned that damage to reverse osmosis membranes is directly linked to on-site disinfection operations, which means the issue stems from improper handling by the on-site technical team. However, the technical staff refused to take accountability and shifted blame to the procurement department, claiming the purchased DuPont RO membranes were counterfeit.
As the engineering contractor, we could not accept such accusations against our supplied DuPont membranes. We took the following steps to resolve the dispute:
First, we arranged DuPont’s China-based representatives to visit the site and clarify the facts. They confirmed the membranes were authentic and explained that damage could still occur under improper operating conditions.
Even after this on-site verification, the client remained skeptical and continued to allege the membranes were fake.
With no other recourse, we requested DuPont to issue an official certificate of authenticity referencing the serial numbers of the delivered membrane batch, which finally settled the whole matter.
This incident illustrates a key point: issues can arise with both DuPont branded membranes and domestic alternatives, and such failures are inevitable to some extent. We must view equipment malfunctions rationally. Human beings can fall ill unexpectedly, let alone mechanical equipment.
