AvPURE™

AvPURE is designed for waters where conventional media-based treatment can struggle, including high-organic and mixed waste streams. This added pretreatment step helps address matrix complexity before downstream adsorption and polishing.

By breaking down organics and transforming some PFAS precursors, AvPURE helps maximize the effectiveness of carbon and resin treatment. Case study findings show improved treatment outcomes and lower changeout demand when AvPURE is included in the treatment train.

In airport AFFF transition testing, AvPURE with granular activated carbon (GAC) and ion exchange achieved total PFAS below 15 ng/L in a single pass. Without AvPURE, conventional GAC and ion exchange left significant residual PFOS and 6:2 fluorotelomer sulfonate (6:2 FtS).

Skid-mounted and containerized AvPURE systems support rapid deployment where space, schedule and throughput all matter. This modular approach helps treatment move forward on sites with limited footprints and demanding operating conditions.

AvPURE can support treatment of spent cleaning solution, rinse water and other PFAS-impacted waters generated during aqueous film-forming foam (AFFF) transition. It also supports broader remediation needs where high PFAS concentrations and complex chemistry require adaptive treatment design.

Onterris pairs laboratory optimization with treatment design, permitting and analytical verification to reduce uncertainty before mobilization. This approach helps clients move from feasibility to field performance with greater confidence in treatment outcomes.
