Mobile VA Reduction using Nanofiltration (US Patent 7651616)
Advantages:
- 30% VA reduction on a single pass, minimum.
- 475 - 1,000 gal/hour
- One pass means no internal recirculation.
- No heat increase.
- Lower treatment pressure (300 - 600 psi) = lower wine stress
- Friendly and continuous onsite supervision by skilled operators
- On-site, small volume processing (15 - 130 gal) using 'Sweetspotter'
- Cost effective - even for lower quality wines.
