Gigamem® Ultrafiltration Membrane Modules
This unique family of Gigamem membrane modules, manufactured by Polymem S.A., combines efficiency and accessibility for a new, innovative approach to ultrafiltration. The Gigamem modules feature industry-leading, fouling-resistant Neophil™ PVDF membrane fibers, which improve filtration performance and lower operating costs. The unique Gigamem module design provides for a permanent membrane housing with replaceable membrane bundles. The Gigamem modules are easily accessed for maintenance, and the membrane bundles can be easily removed and replaced at the end of their operating lives. Gigamem’s approach to module replacement is less expensive, more environmentally friendly, and easier to accomplish than any other commercial membrane product.
Gigamem Family
UF240 and UF80G module sizes are available to accommodate a wide range of capacities.
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 5,813 ft2 (540 m2).

Due to their compactness, Gigamem UF240 modules are uniquely well-suited for applications in which a small system footprint, design flexibility, or containerization is desirable.
THE GIGAMEM UF80G MODULE
The Gigamem UF80G module with 7 individual fiber bundles and 782 ft2 of filtration surface competes effectively with traditional rack-mounted ultrafiltration systems, including universal racks, while bringing all of the advantages of the innovative Gigamem design.

The high capacity UF80G membrane module is well-suited to treatment systems with a capacity of less than 100 gpm. Systems incorporating the UF80G benefit from low membrane replacement cost, easy maintenance, and low cost of operation
Application
The Gigamem UF240 and UF80G ultrafiltration modules have unmatched versatility due to their high capacity, ease of maintenance access, small footprint, and low cost of ownership. In addition to the applications listed below for stand-alone and integrated water treatment systems, the UF80G has been designed with universal skid applications in mind, where it brings unprecedented Gigamem value to new systems and as an after-market replacement for other commercial modules.
- Industrial process water
- Pretreatment to RO and desalination
- Drinking water production
- Wastewater reuse – generation of Class A reclaimed water
- And more
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
