Chemistry
Chemical Tolerance
- Chlorine: Intentional exposure of TFC®-HR membrane to free chlorine or other oxidizing agents (e.g., permanganate, ozone, bromine, iodine) is not recommended.
- Free chlorine tolerance is approximately 1,000 ppm-hours based on testing at 77°F (25°C), pH 8. This tolerance may be significantly reduced if catalyzing metals (e.g., iron) are present or if pH and/or temperature are different.
- Sodium metabisulfite (without catalysts such as cobalt) is the preferred reducing agent.
- Chloramine tolerance is approximately 60,000 ppm-hours in the absence of free chlorine, based on testing at 77°F (25°C), pH 8.
- Cationic (Positively Charged) Polymers and Surfactants: Exposure to these chemicals during operation or cleaning is not recommended, as TFC®-HR membrane may be irreversibly fouled.
Lubricants
For element loading, use only the recommended silicone lubricant (or approved equivalent), water, or glycerin to lubricate O-rings and brine seals. The use of petroleum-based lubricants or vegetable-based oils may damage the element and void the warranty.
