ZwitterCo

We founded ZwitterCo in 2018 to develop membrane solutions for difficult separations in industrial, agricultural, and food processing applications. Our membranes use zwitterionic chemistry to attract water molecules instead of organic compounds, preventing permanent organic fouling. This allows us to treat industrial wastewater and process streams beyond the capabilities of traditional filtration.

Our products — Evolution, Elevation, and Expedition membranes — are used to treat complex wastewater for discharge, purify effluents for reuse, and improve efficiency in food processing. We serve industries in over 20 countries, including food and beverage (dairy, protein, beverage), agriculture, industrial, bioprocessing, and grain processing.

For example:

• Evolution anti-fouling membranes reduce costs and increase productivity in dairy processing. They allow for shorter cleaning cycles and use less chemicals, water, and energy.
• Elevation membranes have cut cleaning and chemical costs by 50% in landfill leachate treatment.
• In bioprocessing, Evolution anti-fouling membranes provide reliable operations and higher concentration factors, reducing expenses.
• In food and beverage, our Elevation and Evolution products handle high-fouling applications for process water reuse, ingredient concentration/recovery, and byproduct management.
• Our Expedition membrane solutions purify products and treat wastewater in complex grain processing and biorefining.

All our membranes are built with ZwitterShield™ technology. They are fully chlorine-intolerant, run at low pressure without removing salts or small molecules, and can replace biological systems or coagulation/flocculation processes for organic removal.

We founded ZwitterCo in 2018 to address industrial and agricultural water scarcity through better water treatment and reuse. Our goal is to make it practical for industries to recycle water and recover products using advanced filtration. We offer solutions that reduce chemical demands, maintain steady performance, and last.

We are committed to engineering excellence and continuous innovation. We envision a world that produces billions of gallons of clean water daily from unconventional resources, preserving freshwater reserves.

Our team has over 60 water and membrane technology experts. We foster a culture where creativity and engagement contribute to public health and environmental sustainability. We encourage employees to innovate and implement solutions for water and wastewater challenges.

Our work environment is fast-paced, with employees taking ownership of projects and engaging in hands-on prototyping. We support a flexible hybrid work-from-home/on-site model.

We provide a benefits package, company equity, and a flexible hybrid work-from-home/on-site model.
