PFAS concentration with SELPAXT

Reverse osmosis (RO) is a common method for removing PFAS in drinking water treatment. This process uses a synthetic thin film polymeric membrane to filter out PFAS, achieving up to 99% removal efficiency according to the EPA.

However, RO treatment generates a residual PFAS waste in the form of reject brine, constituting 20-30% of the treated water. SELPAXT technology can concentrate this residual waste to less than 0.1%.

SELPAXT is ideal for PFAS removal 
SELPAXT, our unique and patent-pending technology that delivers efficient removal of more than 90% of both long and short PFAS chains from water. Ideal for high-concentration PFAS water streams, SELPAXT ensures consistent, cost-efficient removal over extended periods of time.

If you want to reduce your residual PFAS waste, contact us and let us analyze your water.
