Bentonite for use during crossflow filtration
Blancobent UF is a highly purified and particularly effective powdered sodium-calcium bentonite formulated for use in conjunction with crossflow filtration. Due to the preparation of the bentonite and the absence of particles >100 μm, Blancobent UF does not cause excessive abrasion to crossflow membranes. Owing to its defined particle size distribution, it is compatible with direct dosing into hollow fiber membrane crossflow systems. In this way, filtration and stabilization happen in one step! Blancobent UF has fine particles and is free of crossflow-damaging grit and sand.
Add Blancobent UF slowly to approximately 10 times its weight of warm water under constant stirring. Allow a rest period of 30-60 minutes, then stir again thoroughly. Let the mixture swell for 6–12 hours. Dispose of supernatant and add remaining bentonite slurry to the wine while thoroughly mixing.
Dated expiration. Store in a dry, odor-free and well-ventilated environment below 25°C (77°F). Reseal opened packaging immediately.
