Nanofiltration can be used to separate succinic acid (SA) from other organic acids in a fermentation broth. However, commercial nanofiltration membranes insufficiently selective since some produced have similar molecular weights. SA production biomass entails separation of the concomitantly such as acetic acid, formic pyruvic etc. In this study, five were tested for rejection and selectivity un...

Abstract In this work, pilot-scale nanofiltration was used to obtain aqueous solutions rich in hydroxytyrosol and tyrosol from olive oil by-products. A large-scale simple process involving mill standard machinery (blender decanter) for the pomace pre-treatment with water. The extract then directly fed a unit concentrated by reverse osmosis. Final concentration factors ranged between 7 9 4 tyros...
