CA-NA Bentonite for use with Pall Oenofine XL Crossflow System
UltraBent PORE-TEC UF was specially developed for protein stabilisation in connection with PALL Oenofine XL Crossflow System crossflow microfiltration systems.
Ultrabent is a granulated calcium-sodium bentonite. Due to the fineness of the bentonite and the absence of particles > 100 μm, it does not cause any abrasive wear to crossflow membranes. Owing to the defined particle-size distribution it is excellently suitable, after pre swelling, for direct dosing into hollow fibre membranes. In this way, clarification and stabilisation need only one process step. Purity and high protein adsorbency reduce the dosage as against conventional bentonites.
Bench trials recommended for wine
Stir UltraBent PORE-TEC UF slowly into a 5–10 fold of water, ensuring constant stirring. After a rest period of 30–60 minutes, the suspension is again thoroughly mixed and then allowed to swell for a minimum of 4–8 hours. Pour off supernatant, stir the bentonite suspension once again, then add to the wine or juice. The use of warm water facilitates handling and reduces the swelling time.
