Reduced Cleaning Costs. More Uptime.
ZwitterCo’s next evolution of membrane products is PCM: a sanitary UF membrane designed to replace conventional 5-30 kDa UF membranes in a variety of food and dairy protein concentration applications. With their anti-fouling zwitterionic chemistry, Evolution PCM spiral elements can enable the simplest membrane cleaning program ever for protein concentration.
Minimize cleaning time
Evolution PCM can reduce cleaning time by an hour or more per day—giving operators precious time back to focus on other critical tasks and producing more.
Decrease cleaning costs by 50% or more
Evolution PCM elements can eliminate multiple steps from a cleaning program, saving money on chemicals, water use, and utilities.
Produce more sustainably
Evolution PCM elements support more sustainable operations and help lower carbon intensity scores by reducing chemical, water, and utility usage.
Simple implementation
Evolution PCM elements are direct replacements for industry-standard products—no system modifications or new CAPEX required.

- 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 PCM 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 PCM is expected to be offered in FDA-compliant elements by the end of 2025.
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 PCM membranes will last, ZwitterCo is so confident that Evolution PCM membranes will last longer than conventional membranes that we guarantee it through two different sales models. Please contact ZwitterCo to discuss purchasing options.
