Multiple Options in Downstream Processing

From proteins, amino acids, enzymes, and final products, Evolution membranes can help in a variety of ways.  

What Challenges Can ZwitterCo Solve for You? 

Enzyme production

Evolution anti-fouling membranes increase productivity and enable stable operations in enzyme separation, purification, and concentration.

Industrial biotech manufacturing

Achieve longer production runs, more stable flux, and lower operating costs with membranes that provide the highest resistance to organic fouling.

Organic acid purification

Processing organic acids post-fermentation is efficient and highly productive with Evolution anti-fouling membranes.

Alternative protein concentration

Experience less frequent and easier cleanings with Evolution anti-fouling membranes in the production of alternative proteins.

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.
