ZwitterCo developed the industry’s first brackish water reverse osmosis membranes to use zwitterionic technology to deliver unprecedented fouling resistance. Our reverse osmosis elements offer the most stable performance on high-fouling streams and can be fully restored with either a water flush or a mild cleaning, resulting in at least twice the membrane life.

ZwitterCo RO is designed to replace traditional reverse osmosis membranes that are struggling with biofouling or organic fouling from surface water or wastewater feed sources. A simple drop-in replacement can lower operating costs and cleaning frequency by up to 90% and allow systems to operate at maximum capacity with minimal downtime.

Superfiltration membranes are a new separation class between ultrafiltration and nanofiltration. ZwitterCo superfiltration membranes deliver unprecedented fouling resistance, low energy requirements, wide pH tolerance, and the ability to be cleaned with chlorine.

Superfiltration membranes are designed for fractionating dissolved components, like capturing protein while passing inorganic molecules. Our membranes are engineered tightly enough to remove fats, oils, grease (FOG), and high-strength organics, providing ideal pre-treatment for reverse osmosis in wastewater.
