Polyethersulfone membranes were prepared from quaternary systems containing N,N-dimethylacetamide （DMAc） as solvent, polyvinylpyrrolidone （PVP） as constant additive and acetic acid, acetone and water as variable additives. Phase inversion via immersion precipitation was employed for manufacturing of membranes. The prepared films were immersed in the mixture of pure water and 2-propanol （30/70 vol%） as the non-solvent. Acetic acid caused an increment in the flux at high polymer concentration （16 wt%） and a decline in the flux at low polymer concentrations （10 wt% and 13 wt%）. Acetone and water as the solvent in the casting solution declined the flux at any polymer concentration tested. The morphology and performance of the prepared membranes were investigated by scanning electron microscopy and separation experiments using milk.as the feed.

In this paper, an analysis of the possibilities of development of milk.processing activity was made, using as financing source the public funds provided by the Common Agricultural Policy and the distribution of the investments in Romania. All the EU member states gain 99.6 billion through the European Agricultural Fund for Rural Development, the period 2014-2020, of which Romania has received the total of 8.128 billion euros. Through the 2014-2020 National Rural Development Program （NRDP 2014-2020）, sub-measure 4.2 ＂Support for investment in processing/marketing of agricultural products＂（2014）, Romania is falling Regulation （EC） 1305/2013 in measure 4 ＂Investments in physical assets＂（2013） and contributes to increasing the value added of products on local markets and inter-professional organizations, the establishment and development of small businesses and job creation. Until now, in the milk.processing sector, investments of 93,918,043 euros were made, about 50% （47,667.41 euros） of which from public funds.
