Save Money on Cleaning and Give Time Back to Production

Evolution SF membranes feature an anti-fouling zwitterionic chemistry that enables faster and simpler cleaning programs, saving money and creating more uptime for production. FDA-compliant full-fit spiral Evolution SF membranes are now available for whey and milk processing.

More time for producing

Evolution SF can reduce cleaning time by one hour or more per day—freeing operators to focus on critical tasks and increasing system uptime.

Save 50% on cleaning costs

The simplified cleaning program enabled by Evolution SF membranes eliminates cleaning steps, saving money on chemicals, water use, and utilities.

Support sustainability goals

By minimizing water, chemical, and energy use, Evolution SF membranes offer more sustainable operations.

No system changes required

Evolution SF membranes are direct replacements for conventional products so that no system modifications are necessary.

FAQs for
Evolution SF

Here you’ll find clear answers to the questions we get most often from customers in the field.

  • Overall cleaning costs can be reduced by over 50%. The total will depend on the current cleaning program in use with conventional membranes.
  • Each step removed from the program will save about an hour of time and reduce water demand by about 25%. A simplified cleaning program also translates to less wastewater to treat.
  • Removing only the enzyme step from the program can lower chemical costs by about 50%.
  • Customers have experienced a decrease in cleaning-related water usage of up to 40%.

A variety of feed spacers are available:

  • 30 mil
  • 46 mil
  • 65 mil
  • 80 mil

The following element diameters are currently offered for 38” long elements:

  • 8.0” (8038)
  • 7.8” (7838)
  • 6.4” (6438)
  • 6.3” (6338)
  • 3.8” (3838)

Sanitary-stye 1812 test elements are also available

ZwitterCo is willing to make element sizes not listed on the data sheets. Please contact ZwitterCo to discuss your specific opportunity further.

No. Evolution SF membranes are compatible with new and existing membrane systems and designs. Special system designs or modifications are not required.

These elements look and feel like traditional sanitary spiral elements with a polypropylene outerwrap and no ATDs. They are available in industry-standard dimensions and feed spacers.

FDA compliance:

  • Evolution SF elements are FDA-compliant for whey and milk processing. Other applications are evaluated on a use-case basis.

Regulation (EC) No 1935/2004

  • ZwitterCo is pursuing certification for 2026.

ZwitterCo is pursuing a number of other certifications requested by our clients with a target for late 2025 or early 2026, depending on the specific product. These include:

  • Halal
  • Kosher
  • 3A Sanitary Standard 45-03
  • USDA

Maximum operating temperature is currently 55°C; maximum cleaning temperature is 50°C. 

The primary cause of membrane failure is from frequent chemical cleanings – daily multi-step programs in the case of most food processing streams.

ZwitterCo anti-fouling membranes fully recover performance with fewer chemical steps, resulting in longer operating life.

While there is no single answer for how long Evolution SF membranes will last, ZwitterCo is so confident that Evolution SF membranes will last longer than conventional membranes that we guarantee it through two different sales models. Please contact ZwitterCo to discuss purchasing options.
