What ZwitterCo does
ZwitterCo is a privately held membrane technology company founded in 2018 and headquartered in Woburn, Massachusetts, with an additional research presence in Boston. The company develops and manufactures filtration membranes built on proprietary zwitterionic polymer chemistry that attracts water molecules rather than organic compounds, preventing irreversible organic fouling in industrial and food-processing water streams. Its product portfolio is organized into three families aligned to application severity: Evolution membranes (sanitary, FDA-compliant, for dairy and biotech processing including protein concentration, whey and lactose processing, and permeate polishing), Elevation membranes (industrial water and wastewater treatment using ZwitterShield additive chemistry, including brackish and high-pressure RO), and Expedition membranes (high-strength industrial wastewater using ZwitterCore standalone polymer chemistry, handling extreme FOG, BOD, and COD loads). Underlying technology platforms are trademarked ZwitterShield (additive coating applied to conventional membrane chemistries) and ZwitterCore (next-generation water-permeable zwitterionic copolymer membranes).
ZwitterCo monetizes through direct enterprise sales of membrane elements via outright purchase, subscription with process guarantee (for Evolution), and engineered systems plus rental equipment (5-80 GPM, 3-36 month terms). Revenue is also generated through engineering and field services including startup, commissioning, training, and operating support. Distribution combines direct field sales with engineering, procurement, and construction (EPC) channel partners such as ESMIL Process Systems in Europe and Fluid Quip Technologies in grain processing and biorefining. Customer outcomes documented in case studies include 50-96% reductions in cleaning costs, 80% reductions in cleaning frequency, 40% reductions in cleaning-related water use, and payback periods measured in months across landfill leachate (Serpol, AST), bioprocessing (Solugen), dairy processing, power generation, and refining applications.
The company has raised $99 million in total funding across six disclosed rounds including a $33 million Series A led by DCVC in September 2022 and a $58.4 million Series B led by Evok Innovations in July 2024, with participation from strategic investors BHP, Munich Re Ventures, and MANN+HUMMEL alongside financial investors. Regulatory milestones include FDA compliance for food and dairy membranes achieved in 2025 and NSF/ANSI/CAN 61 certification for industrial water membranes, with EU Regulation 1935/2004, Halal, Kosher, 3A Sanitary, and USDA certifications pending. The company has been recognized through Global Water Awards (2023 Breakthrough Technology Company of the Year), Fast Company Most Innovative Companies (2024), and the Edison Innovation Award (2024).

Product overview
ZwitterCo offers a multi-brand membrane product portfolio organized into three distinct product lines: Evolution membranes (Evolution SF, PCM, and RO) for sanitary food and dairy processing applications; Elevation membranes (High Rejection BWRO, Low Energy BWRO, and High Pressure RO) for industrial water and wastewater treatment using ZwitterShield technology; and Expedition membranes (Superfiltration) for high-strength industrial wastewater using ZwitterCore technology. The company also provides complete systems and rental solutions. All membranes feature proprietary zwitterionic chemistry that prevents irreversible organic fouling, enabling simplified cleaning programs, reduced chemical costs, and extended membrane life compared to conventional membranes.

ZwitterCo competitors and assessment
Company assessmentBroad incumbents
- DuPont Water Solutions: DuPont (formerly Dow FilmTec) is the largest RO/NF membrane incumbent globally, offering FilmTec elements that compete directly with ZwitterCo's Elevation and Expedition lines in industrial water and wastewater applications. ZwitterCo positions as a higher-fouling-resistance drop-in replacement for FilmTec installations.
- Toray Industries (Membrane Division): Toray is a leading global RO/NF/UF membrane producer used widely in industrial water and dairy processing, overlapping directly with ZwitterCo's Elevation and Evolution product lines. Its broad portfolio and established EPC relationships set the incumbent benchmark ZwitterCo must displace for greater organic-fouling tolerance.
- Hydranautics (Nitto Group): Hydranautics is one of the top three RO membrane manufacturers worldwide, with deep presence in industrial wastewater and dairy/food applications. Its high-rejection and low-fouling elements compete head-to-head with ZwitterCo's Elevation BWRO products.
- SUEZ Water Technologies & Solutions: SUEZ supplies membrane-based water and wastewater treatment systems plus service contracts to the same industrial buyers (dairy, food, landfill leachate, refining) that ZwitterCo targets. It competes as a full-stack systems provider rather than pure membrane seller, against ZwitterCo's Systems & Rentals offering.
- Veolia Water Technologies: Veolia operates the largest installed base of industrial UF/RO/MBR systems globally across dairy, food & beverage, and waste-to-energy clients, competing with ZwitterCo on tenders for new membrane skids and consumables replacement cycles.
- LG Chem (NanoH2O / Water Solutions): LG Chem's NanoH2O thin-film nanocomposite RO membranes are positioned on high-rejection brackish and seawater applications, an adjacent competitive set to ZwitterCo's Elevation BWRO. Both target industrial and municipal buyers seeking durability in fouling-prone streams.
- Pall Corporation (Cytiva): Pall supplies tangential-flow filtration and single-use membranes widely used in bioprocessing — a primary ZwitterCo Evolution bioprocessing segment. Customers evaluate Pall alongside ZwitterCo for downstream processing separations, enzyme production, and bioprocessing protein concentration.
Direct peers
- Koch Separation Solutions: Koch (KSS) is a mid-sized specialty membrane and systems manufacturer competing directly with ZwitterCo in industrial UF/RO for food, dairy, and wastewater applications, including with anti-fouling element lines that overlap with Evolution and Elevation.
- Pentair X-Flow: Pentair X-Flow supplies UF/MBR hollow-fiber and capillary membranes used in industrial wastewater and food processing, overlapping with ZwitterCo's Expedition and Elevation lines on high-fouling streams and offering similar EPC integration.
Emerging players
- 3M Liqui-Cel: 3M has membrane contactor and hollow-fiber filtration products targeting industrial water and process gas/liquid separation, with partial overlap to ZwitterCo's high-purity industrial water and bioprocessing use cases.
