Additional Physical Dimensions:
- For male elements, Dimension "D" (protruding permeate tube) is:
- 30.5 mm (1.2 in) for modules 4014-XL and 4021-XL
- 26.7 mm (1.05 in) for module 4040-XL
Test Conditions for Permeate Flow Rating: The permeate flow values listed above are based on the following test conditions:
- 1,500 ppm NaCl
- 10.3 bar (150 psi) applied pressure
- 25°C (77°F)
- 15% recovery
- pH 6.5 - 7
- 30 minutes operation Flow rates will be no more than 15% below the values shown.
Important Notes:
- Pretreatment is recommended for the removal of free chlorine and other oxidizing agents to prevent damage to membranes. Oxidizing agents, such as free chlorine, in contact with polyamide membranes may result in shortened operating life or membrane failure. Such oxidation damage is excluded from warranty.
- Refer to the manufacturer's guides for detailed information on cleaning (TSG-C-001), operation (TSG-O-012), element start-up (TSG-O-005), and storage (TSG-O-009 & TSG-O-01).
