PFAS removal technologies

Advanced Selective Water Treatment

SELPAXT is an advanced water treatment technology designed to effectively remove PFAS contamination from various water streams, including landfill leachates, industrial process water, firefighting training grounds water, and more.

Utilizing the innovative surfactant-ligand assisted membrane filtration (SAMF), SELPAXT combines proprietary surfactant chemistry and optimized membranes to achieve high removal rates for both long and short-chain PFAS, ensuring consistent performance and minimal waste.

With scalable solutions housed in ISO-certified containers or custom-built installations, SELPAXT offers flexible deployment options tailored to specific site needs. The system features automatic regeneration and remote monitoring to maintain optimal operation, making it a reliable and efficient choice for addressing PFAS pollution.

The final waste concentrate primarily consists of water, with PFAS and surfactant chemicals comprising the remainder. The total volume of waste varies between 0.1% and 1%, depending on the condition of the influent stream. The concentrate is a liquid solution that is most suitable for destruction using the supercritical water oxidation methodology.

SELPAXT Benefits

Effective reduction of short PFAS

Unique capability to reduce both long and short PFAS. Sustainable reduction, typically more than 90%.

Low energy consumption

Low-pressure technology using ultrafiltration. Power required for system less than 1 kWh/cubic meter.

Low residual waste ratio

1,000 times concentration of PFAS waste in relation to treated volume means a PFAS waste ratio of 0.1%.

Low overall TOC sensitivity

The effect of the SELPAXT chemistry is not sensitive to overall TOC levels even though individual substances need monitoring.
