Your Process is Possible with Evolution Membranes.
These novel anti-fouling membranes enable affordable and predictable operations for downstream processing separations that were not possible with conventional membranes. With their stable performance and cleanability, Evolution membranes allow users to achieve high-yield separations despite the presence of foulants.
Zwitterionic Technology Unlocks Anti-Fouling Membranes for Downstream Processing.
Evolution membranes feature a patented zwitterionic chemistry that serves as a permanent barrier to irreversible organic fouling, making them ideal for separations in downstream processing. This proprietary anti-fouling chemistry is extremely hydrophilic while actively displacing or repelling organic compounds so they cannot adhere to and foul the membrane.
These membranes offer the highest resistance to organic fouling with stable membrane flux, enabling users to benefit from simpler cleaning programs and reliable operations. Food processors, biotech users, industrial enzyme manufacturers, and other companies utilizing downstream processing can achieve higher product concentrations and increase achievable purity while supporting sustainability targets.

What Challenges Can ZwitterCo Solve for You?
Enzyme production
Achieve stable and scalable enzyme manufacturing.
With novel anti-fouling technology, Evolution membranes allow enzyme manufacturers to reliably purify and concentrate streams where conventional membranes might have failed. By minimizing gel layer formation at the membrane surface, Evolution membranes increase productivity with higher and more sustainable average flux.



“Without ZwitterCo membranes, our process would not be possible or profitable.”
– Dr. Konrad Miller, VP, Manufacturing, Science, & Technology, Solugen
Industrial biotechnology manufacturing
Increase plant efficiency.
Evolution membranes operate at a more stable flux than conventional membranes, resulting in a higher average flux, allowing users to benefit from greater productivity and longer runs before cleaning. This allows for producing more from existing equipment with stable and predictable performance, increasing overall plant efficiency.

Organic acid purification
Longer production runs and stable flux.
Evolution membranes offer the highest resistance to organic fouling, which results in stable membrane flux and less frequent cleanings.
Downstream processing to produce organic acids becomes more predictable and profitable by utilizing these anti-fouling membranes. In addition, users reduce water, chemical, and energy use with Evolution membranes, allowing them to make sustainability gains.


Alternative protein concentration
Easier and less frequent cleanings.
Experience the simplest membrane cleaning program possible for protein processing while achieving full permeance recovery, thanks to Evolution membranes’ high resistance to organic fouling.
By cleaning less frequently while recovering performance, users achieve longer production runs, higher product yield, and lower operating expenses.
