Performance
SAFF ® performance at a glance:
Traditional remediation technologies can be challenged by waters that present with high organics, co-contaminants or complex cross chemistries, but SAFF® has been purpose designed to effectively manage all types of challenging source waters and has proven its ability at a variety of complex sites around the world.
SAFF® relies on the surface active nature of many PFAS compounds to allow it to be separated and removed. Depending on the types of compounds that local regulators require to be removed, and the particular PFAS signature encountered at a site, then SAFF® can operate as a standalone technology or we may combine it with proprietary additives or even complementary technologies.
The right configuration at your site can be assessed using the table at the bottom of this page
Three steps to prove if SAFF ® will perform effectively at your site:
SAFF® Predictability Model
SAFF® Bench Scale Testing
SAFF® Full Scale Treatment
SAFF® PREDICTABILITY MODEL
Robust SAFF® is designed to function effectively in all types of PFAS impacted waters and its performance has now been extensively tested in groundwaters, landfill leachates, waste waters and process waters.
This data set has led to the creation of an accurate predictability model, providing you with clarity around how SAFF® is likely to perform at your particular site.
HOW DOES THIS WORK?
Simply fill in your details in the form below and you will be able to input your data to predict the percentage of PFAS removal for your water chemistry

SAFF20
SAFF20 offers a convenient containerised PFAS water treatment plant that suits many lower flow sites. Housed in a 40’ shipping container, the system is the perfect choice for smaller water treatment projects with short to medium term timeframes.
The SAFF20 unit includes an enclosed weatherproof field office for staff to prepare samples and document the day’s activities, along with a control room and equipment storage area.
The SAFF20 is a low maintenance, plug and play system that can be operating within minutes of arriving on site. Its intuitive remote telemetry system means that it requires minimal on-site operator supervision.
- Capable of treating up to 20m3/hr.
- Configured with two primary SAFF vessels and one secondary SAFF vessel.
- Conveniently housed in an easily transportable 40’ shipping container (12.2 x 2.4m footprint).
- Lowest OPEX of any PFAS remediation technology.
- No consumables, such as IX Resin or GAC, are required.
- No solid waste produced. Concentrated PFAS is the only by-product of the process.
- Easily manages cross contamination, high organic and sediment loads, with no reduction in efficiency.
- Includes integrated site office, control room and spare parts storage area.
- Plug and play, self-bunded system which can be operating within minutes of arrival to site.
- Delivered to site using standard container handling vehicles, cranes or forklifts.
- High grade remote telemetry system means minimal operator presence on site.
SAFF40
SAFF40 is the compact workhorse in the SAFF fleet. The containerised solution provides high flow-through capabilities within a portable footprint. The SAFF40 suits the majority of PFAS impacted sites including landfills and source zone contamination areas.
- Capable of treating up to 40m3/hr.
- Configured with four primary SAFF vessels and two secondary SAFF vessels.
- Conveniently housed in an easily transportable 40’ shipping container (12.2 x 2.4m footprint).
- OPEX is many times lower than conventional treatment technologies.
- No consumables required (no IX Resin or GAC).
- No solid waste produced. Highly concentrated PFAS is the only by-product of the process.
- Can manage all contaminated water types from drinking water through to landfill leachates and sewerage.
- Covered workstation for sample preparation and paperwork.
- Highest throughput, lowest treatment cost containerised system available.
- Plug and play, self-bunded system can be operating within minutes of arrival to site.
- Delivered to site using standard container handling vehicles, cranes or forklifts.
- High grade remote telemetry system means minimal operator presence on site.

Using SAFF® only

Using SAFF® + SCRP
* SCRP is a patented method developed by EPOC to micro-dose tiny quantities of a proprietary surfactant based additive at defined intervals within the SAFF process to optimise the removal of short chain PFAS compounds.
* EPOC Enviro’s predictability model historically provides accurate results but we cannot guarantee the results. For greater accuracy please ask us about our Bench Scale testing
SAFF® BENCH SCALE TESTING
Once you have established if SAFF® is suitable for your site’s unique PFAS signature, EPOC can conduct accurate benchtop testing to prove the predictability model. A 25 gallon (100 liter) sample of the PFAS impacted site water is required to conduct these tests. EPOC will use this to conduct both primary and secondary fractionation experiments to test and demonstrate SAFF® performance.
As the Case Studies demonstrate, the results of the bench scale tests show a very high level of correlation with full scale field results and provide our clients with confidence and surety that their investment in a full scale SAFF® system will yield accurate, predictable results.
SAFF® FULL SCALE Treatment
With the confidence of predictive modelling and bench scale results in hand, the client can then either move to full scale implementation or conduct a full scale treatment.
Full scale treatment involves deployment of a SAFF20 system to the client’s site to conduct performance testing on the PFAS impacted waters. The SAFF20 system can process up to 20m3/hr of contaminated waters and categorically establish the performance capabilities of the SAFF® system at scale.
