Summary
Product identification
Veolia's Dairy AF Series Reverse Osmosis (RO) membranes are designed for sanitary applications within the Food & Beverage and Dairy Industry. They utilize a high-performance RO membrane to maximize concentration and dewatering processes, offering superior rejection of dissolved solids and low molecular weight organic constituents like lactose.
Key features:
- Durasan Cage outer wrap
- Standard feed spacers
- Polysulfone parts
- Complies with USDA guidelines for sanitary design and fabrication of dairy processing equipment and applicable 3-A sanitary standards.
Applications:
- Lactose concentration
- Whey and milk protein concentration
- Sugar and juice concentration
- Polishing of permeates for enhanced water recovery and biological oxygen demand/chemical oxygen demand (BOD/COD) reduction for water reuse.
Certifications and Compliance:
- US FDA 21 CFR (Subchapter B, Parts 175, 176, 177, 178, and 182)
- EU Framework 1935/2004/EC and 10/2011
- Kosher and Halal certifications
- BSE/TSE guidance EMEA/410/1 - Rev 2; Section 3.1
Product water
- Average stabilized rejection: 99.5% on 2,000 ppm NaCl at 25°C (77°F) and 225 psi operating pressure.
Operating limits
- Typical Operating Pressure: 200 - 500 psi (1,379 - 3,447 kPa)
- Typical Operating Flux: 5 - 20 GFD (8 - 34 LMH)
- Clean Water Flux (CWF): 14 GFD (24 LMH) @ 225 psi. CWF can vary ±25% and is the rate of water permeability through the membrane after cleaning (CIP) at reproducible temperature and pressure.
- Maximum Operating Pressure: 800 psi (5,516 kPa)
- Maximum Permeate Pressure: 60 psi (413 kPa). Permeate pressure should never exceed the concentrate pressure.
- Maximum Temperature: 122°F (50°C)
- pH Range (during continuous operation): 2.0 - 11.0
- Recommended Pressure Drop over an element: 12 psi (83 kPa)
- Maximum Pressure Drop over an element: 15 psi (103 kPa)
- Maximum Pressure Drop per housing: 60 psi (414 kPa)
- Chlorine Tolerance: 1000 ppm-hours (dechlorination recommended)
CIP Limits for RO Elements:
