The Gigamem vessel is available in stainless steel and polyamide to suit a variety of applications.

THE GIGAMEM UF240 MODULE

World’s Highest Capacity, Most Compact Hollow Fiber Ultrafiltration Membrane Module

The Gigamem UF240 module, like both of the modules in the Gigamem family, is operated in dead-end, outside-in filtration mode. Each self-supporting 24" UF240 module contains 52 individual fiber bundles, which can be independently installed, inspected, repaired, and replaced. Because of the unmatched compactness of its internal design, each module offers a filtration surface of 5,800 ft2 (540 m2).

  • Gigamem UF240 540 m2 membrane module

  • Close-up of the 52 removable membrane elements (each in excess of 10 m2) that are contained within the UF240 membrane vessel

  • Gigamem UF240 540 m2 membrane modules with individual membrane elements that can be easily accessed and maintained

Applications

Gigamem modules have unmatched versatility due to their high capacity, ease of maintenance access, small footprint, and durable, chemical-resistant Neophil PVDF membranes. Applications include:

Due to their compactness, Gigamem modules are uniquely well-suited for applications in which a small system footprint, design flexibility, or containerization is desirable.

Benefits

  • Cost Savings on Frame and Components: Direct connection to headers
  • Easy Handling and Maintenance: The Gigamem vessel remains in place; individual bundles can be tested and replaced as needed
  • Cost Savings on Membrane Replacement: Easy end of life bundle replacement, significant savings on membrane replacement costs
  • Cross-section of Gigamem module illustrating central feed tube, filtration bundle mounting plate and bundle configuration
