Summary
Product Identification
The DairyNF™ Series consists of highly selective nanofiltration composite sanitary membranes. They are designed for the separation of divalent anions and/or organic molecules greater than 200 Daltons from monovalent salts and lower molecular weight organics.
Key features and applications:
- Designed for applications such as whey and milk concentration, de-salting (mineralizing) of whey and other streams, DP1 / DP2 sugar fractionation, and BOD / COD reduction.
- Suitable where low pressure operation and high salt passage are desired.
- All products are USDA-accepted.
- Components conform to FDA regulation CFR Title 21 and "3A Sanitary Standards for Cross flow Membrane Modules, Number 45-01, Section C".
Membrane Specifications:
- Configuration: Sanitary (Full-Fit)
- Outerwrap: Polypropylene net wrap
- Membrane Polymer: Composite Polyamide
- Molecular Weight Cut-off: 150-250 daltons
- Nomenclature: DAIRYNF + Size + Feed Spacer
