How to identify the authenticity of membranes used for water treatment?
Thread Content
The company recently replaced 500 reverse osmosis membranes and 2 ultrafiltration units, and conducting inspections upon arrival turned out to be a challenge. It seems that more of these items are fake than genuine, and even the documentation is hard to determine as authentic or not. In particular, the reverse osmosis membranes from the same brand (Dow) came in two different types of packaging and with varying labels, while the ultrafiltration units lacked any proper markings. There were all sorts of customs declaration documents and certificates of conformity, which only added to the confusion! ! Let’s talk about how to determine the authenticity of these items What are the differences in usage?
The packaging, labels, and ultrafiltration process all lack proper certification – it’s hard to say
There are too many types of membranes these days; it’s too chaotic.
Yes, we have also encountered the same situation here
If it has no manufacturer information, brand name, or batch number, the likelihood of it being a counterfeit is very high; Dow membrane products come with complete labels of all kinds. For identification, one can directly consult experts from Dow as the manufacturer; it is said that each Dow membrane can be traced back to its production line, with clear records available for verification.
Was the problem solved? Learn* it a bit
No, the path to certification is long and difficult
Check whether the documents are complete, and contact the agent. I don’t know anything else; I’ll learn it* a bit
