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 more than seven government contracts deploying SAFF to treat PFAS contaminated groundwater across the United States. See the recent announcement discussing details of a two-year contract funded by the Department of Defense’s Environmental Security Technology Certification Program (ESTCP).

The SAFF® process 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 the SAFF process, 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. 

Due to the potential health and environmental concerns, the U.S. EPA is reviewing regulations and is expected to finalize a maximum contaminant level (MCL) and a national primary drinking water regulation (NPDWR) for certain PFAS in 2024. They also plan to finalize their designation as CERCLA hazardous substances by early 2024 according to a timetable published in December. These anticipated new regulations are expected to go into effect by the end of 2026 and include three long chain compounds (PFOS, PFOA, PFNA), and a group of three short chain compounds (PFHxS, GenX, PFBS).

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 100% removal of PFBS from groundwater in the field, 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.

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: Aclarity’s EOx, AECOM’s DE-FLUORO™, Aquagga’s HALT™, Onvector’s Plasma Vortex, and Revive Environmental’s PFAS Annihilator™.

Each SAFF unit has built-in concentrate storage tanks and secondary containment with alarms in the event of a leak. When those tanks are full, the recommended process is to decant storage tanks by gravity using a hose to a closed drum with external secondary containment. This process minimizes operator exposure and risk of leaks during waste management.

SAFF’s flow range capabilities can vary dependent on your treatment objectives and starting concentrations because it is considered a “batch” system. As batch time increases, fractionation time decreases. On average, it can treat approximately 100 GPM for groundwater and up to 70 GPM for higher foaming waters such as leachate or industrial process water.

Routine maintenance cleaning of a SAFF unit will depend on influent water characteristics. We typically see routine maintenance needed 1-2 times per year for cleaner waters. Landfill leachate, or very hard waters, may need routine acid rinses for descaling, or additional cleaning to remove other solid deposits on a biweekly or monthly basis. SAFF units also contain remote telemetry where some issues can be corrected without physical intervention.

The SAFF40 system, created by EPOC Enviro, is very energy efficient. It provides an estimated rate of 2.5 kwh per 1,000 gallons treated.

Please see the SAFF product data sheet for the specifications required for set-up, including power.

Our SAFF40 system is containerized, pre-designed, and pre-manufactured offsite for rapid deployment without site-specific design. Once the SAFF unit arrives on site, it can be set up for operation within days, and about 2-4 weeks for optimization.

We have SAFF units available now in the United States that can be deployed in less than 30 days. Please contact us if you’d like to learn more.

1,4-dioxane is a chemical widely used for industrial chemical processes starting in the 1950s. The U.S. Environmental Protection Agency (EPA) lists it as one of the most prevalent emerging contaminants and a likely human carcinogen. In the U.S. alone, the contaminant can be found in more than 20% of drinking water, impacting over 90 million people. Similar to PFAS, known as the ‘forever chemical’, 1,4-dioxane is slow to degrade, becoming a persistent environmental problem.

While there are no federal regulations governing 1,4-dioxane levels in drinking water, wastewater or other water sources, 18 states have established some degree of regulation or recommended guidelines. Regulatory pressures are also growing on a global scale, with the European Chemicals Agency adding 1,4-dioxane to its Candidate List of Hazardous Chemicals in 2021.

We’ve selected a gram-positive, aerobic, proprietary bacterium that degrades 1,4-dioxane metabolically.

Allonnia 1,4 D-Stroy in situ solution is commercially available and is focused on treating groundwater. Some example sites include chemical manufacturers, industrial facilities, landfills and government sites.

We are also developing an ex situ 1,4 D-Stroy solution and plan to have a prototype in 2024. We’re seeking sites to trial the ex situ solution. If you’re interested, please contact us to learn more.

The Allonnia 1,4 D-Stroy solution is more robust in groundwater compared to other organisms, such as CB1190. Our results have shown lower final 1,4-dioxane concentration in situ compared to other organisms. We believe it will perform better under existing conditions without additional additives. As an example, a field trial with CB1190 demonstrated up to 50% degradation and our first in situ pilot demonstrated up to 99% degradation year-over-year.
