BlueBarrier™ water treatment for PFAS and micropollutant removal brings together the industry's leading technology that can be reconfigured over time as regulations tighten and emerging contaminants come into focus.
The treatment train combines ozone, filtration systems, and UV disinfection to tackle the water contaminants, provided by the BlueBarrier Alliance partners Atlas Copco, Veolia, Statiflo, Nereus, Desotec and UV Guard.
Testing & Scaling
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.
STAGE 1
Advanced Ozonation
In the first stage, ozone is injected to initiate powerful oxidation reactions that break down a broad spectrum of micropollutants.
BlueBarrier™ uses 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.
STAGE 2
Ultrafiltration
As a second step, the Nereus Ultrafiltration System is used to provide a robust physical barrier, removing suspended solids, bacteria, and colloids from the water.
STAGE 3 & 4
BAC & GAC adsorption phase
In the third and fourth stages, biological activated carbon (BAC) works as a high-performance adsorptive and bio-catalytic barrier with granular activated carbon (GAC) 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.
STAGE 5
UV 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.
