TheWay UF Hollow Fiber Module Technical Datasheet

The TheWay UF Hollow Fiber Module is a pressurized ultrafiltration membrane designed for potable water treatment, industrial process water purification, and pre-treatment ahead of RO systems. Unlike our submerged MBR modules, this UF module operates in a pressurized housing with inside-out or outside-in flow configurations, making it ideal for standalone water clarification without biological treatment.

Key Specifications

Operating Parameters

Performance Description

The UF Hollow Fiber Module operates in dead-end or cross-flow mode depending on feed water quality. For low-turbidity surface water or groundwater (< 20 NTU), dead-end filtration at 80–120 LMH provides the most economical operation with backwash intervals of 30–60 minutes. For higher-turbidity feeds, cross-flow mode maintains stable flux with continuous concentrate bleed. The module achieves > 4 log virus removal and > 6 log bacteria removal, meeting USEPA and WHO drinking water guidelines. SDI of permeate consistently remains below 3, making it an excellent RO pre-treatment solution.

Chemical Compatibility

Storage and Handling

Modules ship wet in preservative solution (0.5% sodium bisulfite). Store at 5–35°C, never allow freezing. Flush preservative with clean water before commissioning. Perform an air integrity test at 1 bar before first use. For shutdown periods exceeding 48 hours, re-fill with preservative solution. Replace preservative every 30 days during extended storage. Always transport modules horizontally in original crating.

FAQ

Q: What is the difference between UF Hollow Fiber and MBR modules?

A: MBR modules are submerged in activated sludge for biological treatment. UF Hollow Fiber modules are pressurized units for physical filtration of water without biological processes. UF modules offer higher flux rates and are used for drinking water, process water, and RO pre-treatment.

Q: Can this module be used as RO pre-treatment?

A: Yes. The UF permeate achieves SDI < 3, meeting the feed water requirements for virtually all RO membrane manufacturers. This extends RO membrane life and reduces cleaning frequency.

Q: What is the expected lifespan?

A: 5–7 years with proper operation and maintenance. Lifespan depends on feed water quality, backwash frequency, and CIP protocol adherence.
