Organic membrane for a high outpout

Filters are equipped with an organic, hydrophilic membrane provided with an asymmetrical structure specifically adapted to wine. The hydrophilic characteristic has been proved as playing a positive and efficient role for controlling the adsorption phenomena of polyphenols and polysaccharides. The asymmetrical structure greatly contributes to keep a steady filtration flow rate, especially with clogging wines.
