Wine, polymeric membrane

Polymeric membrane extraction PME Aq/polymer/aq, Org/polymer/aq, Aq/polymer/org lonizable and neutral e.g triazines, carbamates and organophosphorus pesticides in egg (29), vitamin E in butter (39), organophosphorus pesticides in wine and fruit juice (25). 

Membrane processes in must and wine treatment separation techniques involved in wine technology include membrane processes. Pressure-driven membranes (ultrafiltra-tion, reverse osmosis) play an important role in must and wine treatment and have solved some of the problems in traditional wine making technology. Various polymeric mon-branes of different configurations have been used in must stabilization. 

Poly(vinylidene fluoride) (PVDF) is one of the promising polymeric materials that has prominently emerged in membrane research and development (R D) due to its excellent chemical and physical properties such as highly hydrophobic nature, robust mechanical strength, good thermal stability, and superior chemical resistance. To date, PVDF hollow-fiber membranes have dominated the production of modem microfiltration (MF) ultrafiltration (UF) membrane bioreactor (MBR) membranes for municipal water and wastewater treatment and separation in food, beverage, dairy, and wine industries. In the last two decades, increasing effort has been made in the development of PVDF hollow fibers in other separation applications such as membrane contractors [6,7], membrane distillation (MD) [8-11], and pervaporation [12,13].
