A Patent-Pending Membrane Fabrication Method 

FiBrane membrane

At the core of FiBrane’s technology is a unique membrane fabrication method that constructs membranes from the molecular level up. This approach enables unprecedented control over surface functionality and pore size, allowing each membrane to be precisely tailored to the specific requirements of diverse purification processes.

FiBrane Advantages

Wide range of pore-size tunability 

The pore size range of FiBrane membranes spans from 10 nm to 1,000 nm, covering the range of microfiltration and ultrafiltration applications. This wide tunability enables precise separation of particles, macromolecules, and biomolecules.

Tunable surface functionalities 

With our membrane technology, we can precisely control surface functionality, ranging from hydrophilic to hydrophobic, while remaining PFAS-free, supporting both high performance and environmental sustainability.

Excellent chemical stability 

We offer membranes with excellent chemical stability, capable of withstanding extreme conditions, including wide pH ranges, high temperatures, and high concentrations of oxidizing agents. This durability enables reliable operation under harsh cleaning and disinfection regimes, extending membrane lifetime and reducing operational costs.

Simple fabrication process 

Our patent-pending membrane fabrication method is simple, scalable, and cost-efficient, enabling seamless scale-up from laboratory to industrial production. This approach ensures low manufacturing costs while maintaining consistent membrane quality and performance.

Applications

FiBrane Ultrapure Water Solution

For Green Hydrogen and Power-to-X Applications

FiBrane introduces an innovative membrane-based solution to address the challenges of ultrapure water production, a critical requirement for the rapidly growing green hydrogen industry. We have developed a specialized desalination approach that fills a key technology gap, offering a cost-efficient, energy-saving and reliable alternative to conventional technologies such as reverse osmosis and multiple-effect distillation.

Our solution streamlines green hydrogen production by enabling reliable UPW supply, thereby supporting the global transition toward sustainable energy systems.

FiBrane Filtration Solution

For Biorefinery Separation Processes

Our membrane solutions are applied in plant-based protein production and biorefineries, where challenging feedstocks often lead to severe fouling and high membrane replacement costs. FiBrane membranes address these challenges by enabling efficient separation of target components with lower operating costs and extended service lifetimes.

By unlocking difficult separations from plant-based sources in a cost-effective manner, FiBrane enables customers to improve product yields, process economics, and overall operational sustainability.
