Hello Mansoor,
Several studies have been done and are freely accessible on the Internet. One of them is: "An efficient biotreatment process for polyvinyl alcohol containing textile wastewater" - link for this study is http://www.iwaponline.com/wpt/008/0049/0080049.pdf (2013). For your convenience, i attached the downloaded pdf.

Dear Isabelle,
Thank you for the detailed research paper you have shared. I have gone through it, though I heard about all the three process Biological Degradation, UF and Evaporation but was looking something which someone practical or commercial application of such PVA enriched (small quantity) wastewater before going to main biological treatment section.
Dear Ingavar,Your idea is right if we might be able to coagulate PVA with some compound to make floccs and removed by settling or flotation.
I found Biological or Chemical Coagulation could be a better way to treat, lets have some practical.

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.
