I have also seen several studies on PVA removal. I do not have any experience in this particular application of waste water treatment, but it seems given the low volume one might consider adding some additional compound that could react with the PVA so that it will be caught by the RO but not clogging it? I have not seen this particular avenue discussed on the net.
