Treating the Toughest Industrial Wastewater

Membrane solutions built to handle organic-heavy waste streams. We make it easy to manage the logistics, compliance, or reuse of challenging wastewater.



Our membranes are built from a breakthrough zwitterionic copolymer that can solve organic separation challenges that would be infeasible for other technologies. Our innovation is not a modification of an existing chemistry, but rather a new material that maintains remarkable fouling resistance and precision separation - all at low cost. 

Our mission is to upend the traditional wastewater calculus and help operators implement more sustainable methods of wastewater management.

 Meet the ZwitterCo team here.




Reduce organic-heavy (high BOD, COD, TOC, O&G) wastewater volumes, creating clean permeate that is safe for discharge or onsite reuse.



Remove common organic foulants to protect post-treatment equipment. Improves downstream performance and reduces maintenance and downtime.

Selective Separation


True, size-based separation without charge-interference. Retain valuable nanoscale constituents with consistency and confidence.
