Do you need a low cost, effective, and sustainably engineered PFAS remediation? SAFF is a proven and award winning solution, using a natural process to reduce waste and ensure zero harm to the environment.

PFAS Treatment by EPOC Enviro


From landfill sites, airports, and military bases to sewerage treatment plants, water treatment plants, and industrial complexes, SAFF provides the perfect treatment to meet the standards for maximum PFAS levels in water and your requirements to treat PFAS.

What is SAFF®


Surface Active Foam Fractionation, or SAFF®, is a sustainable remediation treatment that rapidly removes harmful target PFAS contaminants from the environment.

If you are looking for a clean, proven and cost effective PFAS remediation solution, consider the many benefits of SAFF.





SAFF® is a sustainable, multi-stage remediation treatment that uses aeration to rapidly remove target PFAS contaminants from water.

The process involves: 

  • Primary stage: use of foam fractionation to rapidly separate detectable target PFAS contaminants from water
  • Secondary and tertiary stage: further use of foam fractionation to concentrate PFAS contaminants and create a PFAS rich hyper-concentrate, ready for destruction
  • Remediation complete: following final analysis, clean water is safely returned to the environment


PFAS molecules are slippery critters. They migrate through soil and water with relative ease, while at other times they hang around layer upon layer on surfaces for way longer than we’d like them to. 

Foam fractionation uses rising columns of bubbles to separate these molecules from a liquid solution. The bubbles then form a foam at the top of the column, which is then removed from the solution. 

EPOC Enviro has refined foam fractionation to enable physical separation of PFAS from water using nothing more than aeration. The technology then concentrates the PFAS hyper-concentrate into a small volume ready for destruction.

We put air in – we pull PFAS out.

The SAFF Difference


SAFF is proven over many years on multiple sites to rapidly remove criteria PFAS compounds from water including 100 per cent of PFOS/PFOA.

Cost effective

SAFF comes with low and predictable CAPEX and OPEX costs and offers the lowest cost per treated litre.

Sustainable Engineering

SAFF contributes zero harm to the environment by using no consumables, minimal energy and labor, and produces no waste other than PFAS hyper-concentrate.

Separation, Concentration and Destruction of PFAS


Foam fractionation is used to separate the PFAS molecules from water.

Foam fractionation continues to de-water the PFAS molecules and creates a PFAS rich hyper-concentrate, achieving concentration rates of up to 3.5M times.

Onsite destruction is achieved by destruction technologies, such as electrochemical oxidation or Annihilator technology.

Key applications

Water – SAFF

EPOC invented the SAFF® process for PFAS removal from all types of impacted waters. It effectively strips surface active PFAS compounds down to extremely low levels. SAFF is an energy efficient, low cost, high-capacity process for treating PFAS impacted waters.

Soil – PFAST

The PFAST (Fractionation Assisted Soil Treatment) Process was developed to treat and clean impacted soils and hardstand at highly contaminated sites. The process is a sustainable, high-volume technique applicable to a wide range of soil types. It can process up to 50 tonnes per day of PFAS impacted soil and can treat and recover 90-99% of contaminated soils for beneficial on-site re-use.

Infrastructure – FAIT

The FAIT (Fractionation Assisted Infrastructure Treatment) system uses powerful PFAS scrubbing chemistries combined with foam fractionation to strip residual PFAS compounds bound to valuable infrastructure, like fire-fighting appliances, storage tanks, and sprinkler systems. You can ensure the cost effective recovery and reutilisation of PFAS impacted assets which would otherwise need to be removed and replaced.
