Summary
Product identification
The Dairy Ultra UF Series consists of ultrafiltration (UF) membranes designed for superior flux in food-related processes requiring stringent sanitary procedures.
Typical applications include whey and milk fractionation, where these membranes offer exceptional process flux and protein retention due to a specific durable membrane structure, while also being easily cleanable.
- Membrane Material: Polyethersulfone
- Molecular Weight Cut-Off (MWCO): 10,000 Da
- Performance: Great performance in acid and sweet whey applications.
- Element Features: Patented Durasan* Cage outer wrap, polysulfone parts, standard feed spacers.
- Certifications: Halal & Kosher certification

Operating Limits
- Typical Operating Pressure: 80 - 135 psi (555 – 931 kPa)
- Typical Operating Flux: 5-20 GFD (8–34 LMH)
- Clean Water Flux (CWF) (1): 45-55 GFD (76 - 93 LMH) @ 20 psi & 50°C (1) Clean water flux (CWF) is the rate of water permeability through the membrane after cleaning (CIP) at reproducible temperature and pressure. It is important to monitor CWF after each cleaning cycle to determine if the system is being cleaned effectively. CWF can vary ±25%.
- Maximum Operating Pressure: 150 psi (1,034 kPa)
- Maximum Temperature: 122°F (50°C)
- pH range: 2.0-10.0
- Maximum Pressure Drop:
- Over an element: 15 psi (103 kPa)
- Per housing: 60 psi (414 kPa)
- Chlorine Tolerance: 5,000+ ppm-days
CIP and Disinfection Parameters
The following pH ranges are permissible depending on the cleaning temperature:
- Temperature:
- < 50°C (122°F): pH 1.5 - 11.5
- < 45°C (113°F): pH 1.5 - 11.5
- < 35°C (95°F): pH 1 - 11.5
- < 25°C (77°F): pH 1 - 12
Chlorine Disinfection:
- Recommended Concentration: 180 ppm for 20 minutes maximum during chlorine caustic cycle.
- Maximum Temperature (during chlorination): 50°C (120°F)
- Pre-chlorination pH adjustment: pH must be stabilized at 10.5 - 11.0 before chlorine addition.
- Catalyzers: The membrane element surface must be free of catalyzer presence such as iron or other metals. Oxidizers like chlorine or hydrogen peroxide can accelerate membrane degradation in their presence.
