Summary
Product identification
FilmTec™ Reverse Osmosis (RO) Elements are designed to provide high-quality water for small commercial systems, purifying less than one gallon per minute (0.2 m³/d) of RO water. These membranes are available in various sizes to suit different space requirements.
Key features include:
- FilmTec™ XLE extra low energy elements operate at reduced pressure, contributing to lower energy costs and allowing for the use of lower-cost system components.
- Delivers long-lasting and reliable performance.

General Information
- Proper start-up of RO systems is essential to prevent membrane damage.
- Avoid abrupt pressure or cross-flow variations during start-up, shutdown, or cleaning.
- Gradual changes during start-up are recommended:
- Feed pressure increased gradually over 30-60 seconds.
- Cross-flow velocity achieved gradually over 15-20 seconds.
- Keep elements moist at all times after initial wetting.
- Operating limits and guidelines must be strictly followed to maintain warranty.
- For prolonged system shutdowns, immerse membrane elements in a preservative solution to prevent biological growth.
- Customers are responsible for the effects of incompatible chemicals and lubricants.
- Avoid static permeate-side backpressure at all times.
- The use of this product does not inherently guarantee the removal of cysts and pathogens; effective reduction depends on complete system design, operation, and maintenance.
- Permeate obtained from the first hour of operation should be discarded.
