Stop PFAS Before It Leaves the System

NanoSORB helps wastewater operators capture PFAS earlier in the treatment process, using existing biological treatment infrastructure more effectively. Designed to work within activated sludge systems, it supports stronger PFAS removal, reduces contaminant carrythrough and helps turn a complex treatment challenge into a more manageable operational outcome. It is especially relevant where conventional treatment, including biological systems alone or traditional media approaches, struggles to deliver reliable PFAS performance.

why it matters

Make PFAS control simpler and more effective

Improve PFAS capture in existing treatment trains
Reduce waste spread and downstream risk
Support compliance with lower lifecycle burden

Treat PFAS where conventional systems fall short

Conventional wastewater treatment facilities are not designed to remove PFAS effectively. Biological treatment alone offers limited benefit, and traditional media such as granular activated carbon can lose adsorption capacity quickly in challenging wastewater environments. That can leave operators with PFAS in treated water, added pressure on downstream systems and contaminated residuals that require specialized handling.

NanoSORB addresses this challenge by attracting PFAS in treatment tanks and helping it bind into solids for easier filtration or settling. The result is a more contained PFAS stream, reduced environmental spread and a treatment approach that fits more naturally into existing plant operations. Broader Onterris water capabilities strengthen this by combining treatment integration with scientific testing, risk insight and implementation support.

Integrate with existing biological treatment

Improve capture and separation

Lower operational burden

NanoSORB is built to simplify treatment where conventional PFAS approaches can become expensive, inefficient or difficult to scale.

Longer-lasting performance than traditional media in wastewater applications
Reduced waste generation compared with more complex treatment trains
Lower overall treatment cost potential
Faster treatment kinetics can reduce footprint demands

Support future-ready implementation

How NanoSORB works

NanoSORB introduces a specialized additive into the biological treatment process, where it becomes enmeshed with biological floc and captures PFAS within the solids phase. This helps keep the treatment media in the active process rather than separating out in tankage, while concentrating PFAS into a single residual stream that is easier to manage. The approach can also support removal of other contaminants of concern and improve overall process performance in complex wastewaters.
