Fiberglassed Large Commercial Elements for Challenging Water Conditions

Keep elements moist at all times after initial wetting
For successful operation of Reverse Osmosis (RO) and Nanofiltration (NF) membrane systems, the operation must follow the guidelines provided in the FilmTec™ Reverse Osmosis / Nanofiltration Elements Operation Excellence and Limiting Conditions Tech Fact.

To prevent biological growth during prolonged system shutdowns, it is recommended that membrane elements be immersed in a preservative solution
The customer is fully responsible for the effects of incompatible chemicals and lubricants on elements
