used in the module.

SOLVENT STABILITY PuraMem® membranes are stable in mild and nonpolar solvents2:- e.g. Alcohols (e.g. Methanol, Ethanol, 2Propanol)- Aliphatic hydrocarbons (e.g. Hexane,Heptane)- Aromatic hydrocarbons (e.g. Toluene,Xylene)- Butyl Acetate, Ethyl Acetate- Methyl-Ethyl-Ketone- Methyl-tert-Butyl-Ether PuraMem® membranes are not recommended foruse in aqueous/water mixtures. For
aqueous/organic solvent mixtures, please contact
us for membrane recommendations.
 Female type of spiral-wound module

MODULE POSITION IN HOUSINGTYPICAL MODULE INSTALLATION PROCEDURES

Spiral-wound membrane modules can be installed
either individually or in series in a pressurizedhousing.
1. Membrane module should be installed inside ahousing in a way that the (white) PTFE seal isfacing the feed inlet.
2. Block one side of the module permeate tube,
using an end cap (type and size?).
3. Connect a permeate tube adaptor into the otherside of the module permeate tube (30.15±0.05
mm inside diameter)
4. Hold the module assembly horizontally andinsert it inside the housing slowly. Please keep
the module assembly straight and do not bend
the module or tube, and do not force the module
into the housing (The PTFE seal should be facing
the feed inlet (Side A)).
5. Install the flange with permeate tube into thehousing (Side B) by connecting the permeate
tube adaptor to the permeate tube of the flange
by gently pushing the module assembly fromSides A to B. Make sure the permeate tube
adaptor is aligned with the permeate tube before
pushing, and do not apply excess force onto thetube while pushing.
6. Install the blank flange to close the housing (SideA).

PRECONDITIONING OF MEMBRANE MODULES

PuraMem® Selective, Performance and Flux membranes do

not require preconditioning. Stable membrane performanceis achieved after 3-4 hours filtration.

STORAGE OF USED MODULES

Once installed and preconditioned (wetted), themembrane module should not be removed from themodule housing. If the module will not be used for
prolonged periods, the module housing should befilled with an appropriate organic solvent and themodule stored in situ. The preconditioning
procedure should be carried out prior to re-use.
Please contact us if you have any questions.
