Yes. ZwitterCo offers high-pressure, fouling resistant Elevation RO membranes that are specifically engineered to tolerate high concentrations of COD and other challenging contaminants commonly found in landfill leachate. Their robust performance makes them an ideal choice for reliable operation in difficult-to-treat industrial wastewater streams.

ZwitterCo membranes deliver superior value through performance and operational advantages. They offer:

• Reduced chemical cleaning costs
• Faster and easier cleaning cycles
• Increased system uptime
• High reliability in challenging applications
• Easier and safer plant operations
• Best-in-class organic fouling tolerance

These benefits make ZwitterCo membranes ideal for industrial applications where consistent performance, ease of maintenance, and operational efficiency are critical. Consult our sales experts to learn how these benefits can apply to your system.

ZwitterCo Elevation RO membranes are engineered for applications with high organic loading and challenging wastewater conditions.  

They are an excellent fit if you operate in industries such as:

• Landfill Leachate Management
• Food & Beverage
• Chemical Processing & Refineries
• Heavy Industry

They perform reliably with feedwaters like:

• Wastewater or Leachate
• MBR Effluent
• Industrial Process Water
• High-Fouling Surface Waters

If your current system requires alkaline cleaning monthly or more often, or you’re replacing elements every 2 years or less, it may be time to consider ZwitterCo. Contact our team to assess the membrane fit for your specific operation.

ZwitterCo Elevation RO membranes are designed to be cleaned using commodity cleaners (e.g. caustic soda), making maintenance simple, cost-effective, and operator friendly. Elevation membranes respond quickly to cleaning, typically requiring shorter cleaning cycles and less aggressive protocols than conventional RO membranes. This ease of cleaning helps reduce downtime, improve membrane longevity, and lower operating costs. For specific cleaning recommendations, refer to ZwitterCo Elevation RO Cleaning Guide or speak with our technical team.

The following element diameters are currently offered for 40” long brackish water High Rejection and Low Energy elements with 34 mil feed spacers:

• 8.0” (8040)
• 4.0” (4040)
• 2.5” (2540)

The following element diameters are currently offered for 40” long High-Pressure RO elements with 34 mil and 50 mil feed spacers:

• 8.0” (8040)
• 4.0” (4040)

While membrane lifespan depends on system design, feedwater quality, and operating conditions, ZwitterCo Elevation RO is engineered for extended durability in tough applications. The leading cause of membrane failure is frequent chemical cleaning. Thanks to its high resistance to irreversible organic fouling, Elevation RO enables full performance recovery with fewer and simpler CIP steps, reducing membrane stress and extending membrane life. ZwitterCo is confident that Elevation RO membranes last longer than conventional RO membranes, helping reduce lifecycle costs and improve system reliability.
