Summary
Product identification
DuPont reverse osmosis (RO) membrane elements, specifically the FilmTec™ Hypershell™ RO series, are designed for dairy processing applications, including dewatering and protein concentration. They contain sanitary, high-rejection FT30 reverse osmosis membranes suitable for a wide range of food, beverage, and dairy streams.
The FilmTec™ Hypershell™ RO-8038-FF, RO-8038/48-FF, and RO-390-FF are constructed with a polypropylene outer shell designed to:
- Minimize channeling & fluid by-pass
- Help prevent premature element failures throughout product lifetime
- Improve hydrodynamics of the element
- Comply with FDA Indirect Food Contact standards
The FilmTec™ Hypershell™ RO-390-FF product is highlighted as an industry premier membrane for permeate polishing, offering more active area than competitive elements to maximize performance and potentially reduce capital costs.
Hypershell™ elements require approximately 30% less flow than mesh wrap for an equivalent pressure drop (at 4 psi delta P), indicating potential energy savings.
