We are able to undertake membrane autopsy and provide analytical services in support of clients operations. We can provide simple or advanced autopsy services tailored to the Clients need.
This facility is backed up by the following analytical services:
Removal of anti-telescope devices and fibreglass shroud, appraisal of fouling, digital photography of membrane. Collection of samples for analysis and disposal of membrane.
Feed water analysis from plant to include:
Membrane foulant analysis to include:
SEM will provide high magnification images of the foulant in place on the membrane. This will also allow EDX analysis in which the inorganic composition of foulant can be determined. This method is useful for determining the presence of mineral scale and colloidal fouling
This analytical technique will provide the same information as the EDX analysis carried out as part of SEM work (see above). Full quantitative analysis by XRF requires at least 2 grams of foulant to be available. Semi-quantitative analysis can provide results on 0.02 grams of foulant but can only determine the relative proportions of the elements present (i.e. absolute amounts cannot be determined in this case). XRF is cheaper than SEM-EDX if photographs of the foulant are not required.
