WHAT IS A MEMBRANE AUTOPSY?
Autopsy is a well-proven means of determining the condition of the membrane at the salt separating surface.
The term autopsy is used to describe a series of observations and scientific tests made on a used membrane element.
Highly trained and specialised technicians carry out membrane autopsies at a dedicated Membrane Service Centre.
Our experience has shown that the technician’s experience and expertise is far
more important to gaining meaningful information from the autopsy than the plant’s proximity to the laboratory.
A basic autopsy will take 20–30 man-hours for an experienced technician to complete.
The membrane end-covers and casing are removed and the leaves are unwound. Deposit samples are collected for analysis from the surface.
Small sections of membrane sheet are taken and used to determine flux and rejection properties. Autopsy studies may be quite basic, as is the case with calcium carbonate scaling, or far more complex, as is the case with an apparently clean surface that has suffered severe performance loss.
