Summary
Product identification
DuPont Dairy RO Membranes are reverse osmosis elements specifically designed for dairy processing applications, offering state-of-the-art dewatering and protein concentration solutions. These elements utilize sanitary, high-rejection FT30 reverse osmosis membrane suitable for various 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 bypass
- 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, featuring more active area than competitive elements to maximize performance and reduce capital cost.
Compared to mesh wrap elements, FilmTec™ Hypershell™ elements have less exterior bypassing and require approximately 30% less flow for an equivalent pressure drop (at 4 psi delta P), which can lead to energy savings.
