Recovery of phenolic compounds from orange press liquor by nanofiltration

► Recovery of phenols from orange press liquor by nanofiltration was studied. ► Four different nanofiltration membranes were investigated. ► Average rejections towards anthocyanins, flavonoids and sugars were measured. ► Permeate fluxes and antifouling performance were also evaluated. ► A suitable NF membrane was identified to separate phenolic compounds from sugars.
