PFAS removal from groundwaters using Surface‐Active Foam Fractionation
Results from a field trial commissioned for the Australian Department of Defence at the Army Aviation Centre Oakey evaluated the effectiveness of the Surface‐Active Foam Fractionation (SAFF) process at removing per‐ and polyfluoroalkyl substances (PFAS) in groundwater.
Commercial-scale remediation of per-and polyfluoroalkyl substances from landfill leachate catchment using Surface-Active Foam Fractionation (SAFF®)
This article presents the results from a commercial-scale field trial of the Surface-Active Foam Fractionation (SAFF) process for the removal of per-and polyfluoroalkyl substances (PFAS) from a landfill leachate catchment at the Telge Recycling plant, Sweden.
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.
