Transform through flow
We built Vorta, the vortex cavitation platform already running in bioenergy and wastewater at industrial scale. Vivarta is the next chapter: nanobubbles and crystallisation for mineral processing.
From the vortex up
Cavitation has long been treated as something to avoid, the enemy of pumps and propellers. Our founders turned it into a tool. By spinning liquid into a tight vortex, the platform generates controlled cavitation throughout the bulk flow, releasing exactly the shear, heat and shockwaves a process needs.
The vortex-cavitation IP comes from CSIR-NCL (patents US 9,422,952 & US 9,725,338). On that base, the founders built Vorta (legal entity Vivira Process Technologies) and proved it commercially in bioenergy and wastewater, with industrial-scale installs and results validated in peer-reviewed publications.
Vivarta is that next chapter. We’re building new IP on top of the licensed reactor: nanobubble generation and crystallisation intensification for mineral streams where ultrasound and orifice devices struggle with slurries and full-flow treatment.
Physics over chemistry
We solve fouling, slow kinetics and low yield with engineered fluid dynamics, not with more dosing.
Retrofit, don’t rebuild
The most sustainable plant is the one already standing. Vivarta makes existing assets do more.
Evidence-led
Every deployment starts from data: feed analysis, bench work and a measured trial before scale-up.
