Hello Fawad,
Nice to be in touch again. As you may know, we have assessed over 20 large textile industries in Bangladesh in-depth on behalf of the IFC (World Bank Group) with focus on wastewater. The polymer used in textile finishing/sizing is most likely PVA (poly-vinyl alcohol) which can be recovered at the source and reused. Alternatively the PVA can be captured and fully biodegraded by advanced activated sludge (AAS) biological wastewater treatment. PVA is barely removed by classic activated sludge (CAS) as indicated by Mr. Scheurman 2 days ago which explains the clogging of the downstream UF membranes.

Well, that certainly changes the complexion of the issue. PVA will not react with anionic or with cationic treatments. The question is how exactly is this recovered for reuse?
