SAFF® Applications: Landfill Leachate
Depending on the co-contaminants present, SAFF requires minimal to no pre-treatments beyond gross solids removal to effectively strip PFAS from leachate waters.
The landfill solution
Surface Active Foam Fractionation (SAFF®) is proven as the PFAS heavy lifter at landfill leachate sites, with the naturally elegant SAFF physical separation process harnessing the power of air to effectively remove PFAS from landfill waters.
SAFF is unaffected by high DOC, TOC, TSS or TDS, or the presence of other organic or inorganic compounds or suspended particles. Depending on the co-contaminants present, SAFF requires minimal to no pre-treatments beyond gross solids removal to effectively strip PFAS from leachate waters. This feature enables SAFF to operate in the most extreme and arduous of environments and climates.
With its robust industrial design, and inherent low maintenance characteristics, SAFF is an ideal technology for the complex and highly polluted landfill leachate environment. Its inbuilt remote telemetry capabilities requires minimal operator oversight resulting in labour cost savings. Remote technical supervision by the Global SAFF engineering team means that many problems can be rapidly identified and resolved without site attendance.
Importantly, SAFF creates no secondary waste stream other than small volumes of PFAS hyper concentrate, which, when paired with third party destruction technologies, ensures a closed loop, permanent, on-site destruction technique for PFAS compounds.
Why is PFAS management at landfill sites important?
There is growing global recognition that landfill sites are primary sources of PFAS contamination, as they represent the final resting place for PFAS-containing products. These products typically have waterproof, non-stick and stain resistant properties.
With their high thermal, chemical and biological stability, these forever chemicals can pose long term issues as, if not correctly managed and contained, PFAS has the potential to migrate through soil and water into the surrounding environment.
As the PFAS regulatory environment continues to tighten globally, there is growing pressure on landfill operators to more effectively manage the PFAS contaminants present in their leachate waters.
In the past, landfill leachates have proven challenging for PFAS remediation technologies due to the presence of complex co-contaminants, together with suspended solids, metals and high TOC and DOC. Traditional PFAS remediation technologies, such as those that use GAC or resin, find that the presence of co-contaminants typically causes the media to bind and ultimately block, requiring constant replacement and expensive disposal. In addition to creating a significant secondary waste stream requiring disposal, this approach also incurs high replacement costs for the absorptive media.
