ZwitterCo Superfiltration Membrane Spec Sheets
ZwitterCo Superfiltration
A Paradigm Shift in Membranes
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.

What is Superfiltration?
Membranes in this class may be described as “tight UF”, “open NF”, and “thin-film UF”.
High Organic / Low Salt Rejection
Superfiltration membranes demonstrate high NF-like organic rejection and low UF-like salt rejection.
Molecular Weight Cut-Off
Commonly have a molecular weight cut-off (MWCO) between 500 – 3,500 Daltons and low monovalent ion rejection (< 15%).
Removal of FOG, TSS, and Turbidity
Complete removal of FOG, TSS, and turbidity from wastewater. It will remove larger dissolved organic compounds like proteins, polysaccharides, and humic acids.
What Makes ZwitterCo Superfiltration Unique?
Organic Fouling Resistant
Unique organic fouling resistance with zwitterionic membrane technology.
Designed for Extremes
Designed for extreme concentrations (e.g. >500,000 ppm-hours) of chemicals like chlorine, peracetic acid, and aqueous ammonia, as well as a wide range of pH.
Suspended Solids Removal
Removes dissolved and suspended compounds larger than 1 nanometer/1 kDa molecular weight, providing ideal feedwater to reverse osmosis.
Reimagine your Wastewater
The status quo for high-strength wastewater treatment is expensive and unsustainable. Superfiltration brings the precision and reliability of membranes to historically unfilterable streams.

Hauling
Trucking is the most expensive and least sustainable means of managing wastewater. ZwitterCo’s superfiltration technology drastically reduces hauling volumes by helping recover water you can use.
SuperfiltrationReplaces or Supplements
Biology
Biological processes take up a lot of land area and have frequent upsets, especially when treating hard-to-break-down waste compounds. Superfiltration systems need only a fraction of the floor space and will handle complex organic streams.
SuperfiltrationReplaces or Supplements
DAF
On top of the daily in-line chemical dosing and expensive sludge hauling, DAF processes notoriously yield inconsistent or insufficient treatment results. Superfiltration can reduce or eliminate the use of DAF chemicals, opening the door to waste-to-revenue opportunities, and delivering precise, high-quality effluent.
SuperfiltrationReplaces or Supplements
Tubular
Tubular and other open-channel membrane configurations require high recirculation energy and can still incur severe operating costs from fouling. Superfiltration membranes use 5-10x lower energy and have the fastest and least expensive cleaning methods in the industry.
