SELPAXT

Designed for the PFAS that are hardest to remove

Conventional adsorption technologies – such as activated carbon or ion exchange – can struggle with shorter PFAS compounds, and gradually lose capacity as their media becomes saturated.

SELPAXT takes a different approach. Selective chemistry binds PFAS before separation by ultrafiltration, and the system regenerates automatically rather than relying on a fixed bed of media that wears out – enabling continuous treatment across a broad range of PFAS chain lengths.

How SELPAXT works

SELPAXT is based on Surfactant-Ligand Assisted Membrane Filtration (SAMF).

Proprietary chemistry selectively interacts with PFAS in the incoming water. The PFAS-containing structures are then separated using optimised ultrafiltration membranes.

Automatic regeneration enables continuous treatment, while remote monitoring helps maintain stable performance over time.

Every water stream is different. Water matrix, flow rate, PFAS profile and treatment requirements all influence the right solution. Share your water data with us, and we'll help determine whether SELPAXT is the right approach.
