SAFF® has been proven to be highly versatile, successfully treating hundreds of millions of gallons of PFAS-contaminated water across varied applications including landfill leachate, groundwater, drinking water, process water, and reverse osmosis (RO) reject water – often without pretreatment. View the map of SAFF’s global installations and case studies across applications.
You can also quantify the effectiveness of SAFF® for your site conditions with our free calculator.
We have been awarded eight government contracts deploying SAFF® to treat PFAS contaminated groundwater across the United States. See the announcement discussing details of a two-year contract funded by the Department of Defense’s Environmental Security Technology Certification Program (ESTCP).
SAFF® is a portable, containerized water treatment system which utilizes the natural physiochemical properties of PFAS compounds to adhere to fine air bubbles rising through a narrow water column. As the bubbles rise, they are exceptionally effective in collecting PFAS compounds which are loosely bound to the water molecules. Unlike other PFAS removal technologies such as granular activated carbon or ion exchange resins, no solid adsorbent media is used in SAFF®, so no costly pretreatment, media change-outs and disposal, or breakthrough evaluations are required.
Per- and polyfluoroalkyl substances (PFAS) are a group of synthetic chemicals used in various industrial and consumer products for their water- and grease-resistant properties. They are characterized by a carbon-fluorine (C-F) bond, which is one of the strongest chemical bonds and makes PFAS highly resistant to degradation in the environment.
PFAS can be categorized into two main groups based on the length of their carbon chain: short-chain PFAS and long-chain PFAS. Short chain PFAS are not as hydrophobic and have a shorter carbon backbone compared to long chains, typically consisting of fewer than 8 carbon atoms, such as PFBA and PFPeA.
EPOC Enviro’s Surface Active Foam Fractionation (SAFF®) is effective across a full spectrum of short-chain PFAS compounds and can separate and concentrate both short chain and long chain PFAS through a naturally elegant and sustainable process. The process relies on PFAS’ amphiphilic characteristics to remove the contaminants and can be further enhanced with a dose of an Allonnia booster, which facilitates increased aggregation and subsequent separation. Requiring only a low dosage, the booster pairs seamlessly with SAFF® and is ready to use upon deployment – no additional hardware required.
For example, Allonnia has demonstrated removal of PFBS from groundwater in the field to concentrations below laboratory detection limits, meeting proposed EPA MCLs at three different groundwater sites. If your site has short chain PFAS, reach out to us and we can find the right combination of technologies to meet your needs.
You can use our free calculator to quantify the effectiveness of SAFF® for your specific water type and application.
If you’re not ready to jump into a pilot but want to see SAFF’s capabilities for your site, we can also conduct a bench scale SAFF® test in Allonnia’s lab. The study includes primary and secondary fractionation to estimate PFAS removal and concentration factor, providing a good correlation with full-scale field results.
The test includes analytical and waste management and requires sending 40 gallons of sample contaminated water in five-gallon HDPE carboys. A summary report with analytical results will be provided in 4-6 weeks after receipt of the water sample.
We also offer SAFF10®, a compact and mobile version of SAFF® for pilot studies.

SAFF® concentrate is well-suited for downstream disposal and destruction technologies. Current customers use on or offsite commercial PFAS destruction (i.e., mineralization) technologies, or solidification and solid waste disposal strategies. Other common solutions for disposing of liquid PFAS concentrate include deep well disposal or incineration.
There are several destruction technologies available on the market today, which include electrochemical oxidation, supercritical water oxidation, hydrothermal alkaline treatment, photochemical, plasma, UV-sulfite, thermal oxidizer, photo-activated reductive defluorination, and sonochemical. So far, Allonnia has paired SAFF with the following: AECOM’s DE-FLUORO™, Aquagga’s HALT, Haley & Aldrich’s EradiFluor™, Onvector’s Plasma Vortex, and Revive Environmental’s PFAS Annihilator™.
Please see the SAFF product data sheet for the specifications required for set-up, including power.
The SAFF®40 is containerized, pre-designed, and pre-manufactured offsite for rapid deployment without site-specific design. Once the SAFF® arrives on site, it can be set up for operation within days, and about 2-4 weeks for optimization.
We offer several financial options including straight purchase, monthly lease, or equipment as a service, depending on your need. Contact us to learn more.

Allonnia deploys the SAFF®10 pilot unit on a mobile trailer which can typically be deployed within days, depending on availability and site readiness. It comes fully assembled, minimizing onsite set-up time.
Allonnia deploys the SAFF®10 on a mobile trailer for pilot trials. However, if purchased, the SAFF®10 unit is skid-mounted and can be lifted by forklift and placed on a flat, level surface in a building.
Pretreatment is not typically required for any SAFF®. All SAFFs can handle high TSS, TDS and TOCs with the included bag filters.
The SAFF®10 does not include a heated enclosure. So, in extreme climates, it will need to be placed in a building or heated enclosure.
All SAFFs are designed for autonomous operation with 24/7 remote telemetry available. Ongoing operation requires preventative maintenance and occasional cleaning.
The SAFF®10 uses the same telemetry system as SAFF®40, enabling full remote operation, performance monitoring, and data reporting.
Yes, SAFF®10 includes a dosing system compatible with Allonnia’s foam fractionation boosters. Our boosters improve short-chain PFAS removal and foam quality in low-foaming waters.
All SAFFs can treat any contaminated water type, including landfill leachate, groundwater, surface water, drinking water, industrial process water, and RO reject water.
Yes, all SAFFs produce a PFAS concentrate compatible with any PFAS destruction and disposal technology available today.
