ZwitterCo Superfiltration Membrane Spec Sheets

ZwitterCo Superfiltration

A Paradigm Shift in Membranes

Superfiltration membranes are a new separation class between ultrafiltration and nanofiltration. ZwitterCo 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 SF membranes are engineered tightly enough to remove fats, oils, grease (FOG), and high-strength organics, providing ideal pre-treatment for reverse osmosis in wastewater.

SEE THE TECHNOLOGY

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 dairy wastewater or poultry 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 SF membranes to historically unfilterable streams.

Hauling

Trucking is the most expensive and least sustainable means of managing wastewater. ZwitterCo’s superfiltration technology drastically reduces wastewater hauling volumes by helping recover water you can use.

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.

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.

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.

Let's Get Started

Remove Bulk Organics

Remove tough to fight organics, such as fats, oils, grease, and protein.

Fully Chlorine-Intolerant

Can endure aggressive cleaning without wear and tear

Runs at Low Pressure

Runs at low pressure by not removing salt, sugar, alcohol’s or other small molecules.

Replaces Biological Systems

Replace biological systems or coagulation/flocculation processes commonly used to treat organics.

REGULAR MEMBRANES
