Fumasep FAS-PET-75 is a PET reinforced AnionExchange Membrane (AEM) with low resistance, high selectivity, highmechanical stability, and high stability in pH neutral and acidicenvironments. The polymer backbone for this AEM is based on a hydrocarbonpolymer material.
Fumasep FAS-PET-75 membrane comes in either a 10cm x 10cmor 20cm x 30cm size sheet that is delivered in a dry brown-foil form.
Fumatech membranes are highly sensitive to differences inhumidity and moisture content. Therefore the membranes can vary +/- 0.5cm fromthe original cut sizes. Also due to this sensitivity the manufacturer expectswrinkles to form, however soaking the membranes in deionized water will returnthe membranes to the full size planar state according to the manufacturer.
Applications:Electrodialysis for demineralisation, desalination, acid recovery applicationsand others.
Anion Exchange Membrane
Stability Rang (pH) at 25C: 0 - 8
Thickness: 70 - 80 micrometers (2.76 - 3.15 mil)
Sizes: 10cm x 10cm, 20cm x 30cm
Keep membrane package closed / sealed when unused. Store,handle and process the membrane in a clean and dust-free area. Use only new andsharp knives or blades, when cutting the membrane. Always wear protectivegloves when handling the membrane. Handle with care, be sure not to puncture,crease or scratch the membrane, otherwise leaks will occur. All surfaces incontact with the membrane during handling, inspection, storage and mountingmust be smooth and free of sharp projections.
Dry Form: The membrane can be stored dry foran unlimited amount of time. However, the membrane has to be conditioned(washed and rinsed) prior to use.
Wet Form: Storage for short and medium timescale (hours up to several weeks) may be done in unsealed containers in 0.5 -1.5 wt% NaCl solution or comparable neutral pH electrolytes. For storageover a longer time period a sealed container is recommended using afore saidelectrolyte with ca. 100 ppm biocide (NaN3) to avoid biologicalfouling.
Pre-Treatment and Conditioning:
The membrane is delivered in bromide formand dry form. Depending on application and cell design, assembling is possiblein dry form (without pretreatment) or wet form. For optimum performance it isrecommended to rinse the membrane in NaCl solution (e.g. 0.5 M NaCl solution at25C for 24 hrs) to remove any additive from the membrane. Place the membranesample between stabilizing meshes / spacers in order to avoid curling. Do notlet the membrane dry out since micro-cracks may likely occur during shrinkage.
