Technological Innovation

Thermodiffusive separation, a new phenomenon!

Thermodiffusive separation harnesses temperature gradients to transport ions or molecules, offering a highly energy-efficient and precise method for concentrating complex mixtures. Its ability to operate without functional materials, such as membranes, or chemicals, such as solvents, makes it ideal for sustainable and low-maintenance applications. This technique holds amazing potential for advanced desalination, resource recovery, and environmental remediation in challenging industrial settings.

Multichannel arrangement for separation enhancement

Multichannel thermodiffusion for enhanced performance

The multichannel thermodiffusive separation system, known as the Burgers cascade, dramatically enhances desalination by amplifying small ion concentration differences across multiple channels. This design boosts the separation while maintaining high recovery rates compared to single-channel setups, making it highly efficient and scalable. Its energy-efficient, membrane-free, and chemical-free operation marks a major step forward in sustainable water treatment technology.

Composite structure for enhanced efficiency

Thermodiffusive crystallisation for enhanced resource recovery

Our new crystallisation technology uses thermodiffusion to separate and recover solids from brine without evaporation or chemicals, making it exceptionally clean and sustainable. It relies on organic components and operates with minimal energy input, offering a highly efficient alternative to traditional crystallisation methods. This breakthrough enables scalable, low-impact resource recovery from saline waste streams.

Cost benefit of multichannel thermodiffusion technology

Multichannel thermodiffusion offers a revolutionary, evaporation-free method for brine concentration and desalination, using only low-grade heat and no chemicals. Its unique cascade design is easy to manufacture with conventional materials and manufacturing methods, such as additive manufacturing (3D printing), which enhance separation efficiency, especially at high salinities, where traditional methods struggle. Techno-economic analysis shows that, with access to industrial waste heat and high-pressure operation, this technology becomes more cost-effective than evaporation ponds at salinities above 95 parts per thousand (ppt). Compact, scalable, and energy-efficient, it presents a compelling solution for industries seeking sustainable and economical brine management.
