Advancing PFAS and micropollutant removal with an alliance of water technology specialists
BlueBarrier is Curio Water’s new treatment train for micropollutants and PFAS: a compact, containerised solution that lets utilities and industrial users trial and then scale up a tailored treatment process that combines ozone, filtration systems, and UV to tackle the contaminants of today and tomorrow.
For the first time, with our technology partners, BlueBarrier water treatment brings together the industry's leading micropollutant and PFAS removal technology that can be reconfigured over time as regulations tighten and emerging contaminants come into focus.
Testing & Scaling
How does it work?
Curio’s treatment trains start with rigorous feasibility testing using pilot plants, through our engagement with Cranfield University, to characterise the local water matrix in detail.
This continuous, on‑site monitoring builds a real‑world profile of micropollutants and PFAS, capturing fluctuations over time rather than relying on snapshot samples.
The resulting data is then used to engineer the right sequence and “titration” of the treatment train. The first stage is the oxidisation process, followed by biological activated carbon (BAC), granulated activated carbon (GAC), and finally UV for disinfection. This ensures the final train offers a long term and comprehensive solution that can meet existing and future regulations.
Advanced Ozonation
STAGE 1
In the first stage, ozone is injected to initiate powerful oxidation reactions that break down a broad spectrum of micropollutants.
BlueBarrier uses RoturiⓇ ozonation technology from up2e!, an advanced gas transfer system that dissolves ozone efficiently through nano bubbles directly into the main pipeline, creating a large reaction surface.
This compact, energy‑efficient design maximises ozone contact and reduces gas consumption and footprint.
STAGES 2 & 3
BAC & GAC Adsorption Phase
Filtration
In the second and third stages, biological activated carbon (BAC) works as a high-performance adsorptive and bio-catalytic barrier with granular activated carbon (GAC) works as the polishing step.
BAC adds an extra dimension by supporting microbial communities that biodegrade organic co‑contaminants and helps maintain the adsorption capacity.
GAC provides a deep “sponge” of carbon surface area that captures oxidised organics and long‑chain PFAS, delivering critical polishing and helping to prevent contaminant breakthroughs.
UV Disinfection
STAGE 4
Disinfection
The final stage uses high‑efficiency UV systems from UV Guard to inactivate remaining microorganisms and degrade residual organic contaminants without adding chemicals or by‑products.
UV Guard’s systems bring a proven track record across drinking water, industrial and wastewater reuse applications, offering low‑maintenance operation, compact footprints and straightforward integration into containerised treatment units.
