Foam fractionation is a technology that can be used to remove PFAS contaminants from water. The technology is effective at removing contaminants below drinking water standards, and is also effective at treating high TDS waters.

00:00:00 The video discusses the potential health risks posed by PFAS chemicals, and details the concerns surrounding existing solutions for PFAS remediation. It then goes on to discuss the development of foam fractionation technology, and the advantages it has over traditional remediation methods. The video concludes with a Q&A session.
00:05:00 The presenter discusses the process of Foam Fractionation, which is a physical separation and concentration process that can remove 85% of bolt detectable PFAS from sources. Fine fractionation provides that we've seen that it can also airlift other things that can be found out of solution.
00:10:00 The presenter discusses the technologies they used to try to remediate PFAS contamination, including foam fractionation. Foam fractionation was found to be the most effective method for long-chain PFAS removal, and it was used in combination with other technologies to achieve 100% removal of the contaminants down to drinking water guidelines.
00:15:00 Foam fractionation is a physical separation process that can be used to remove a variety of co-contaminants from water. The technology is cost-effective and can be integrated into an existing water treatment system.
00:20:00 The video discusses the process of foam fractionation, which is a technique used to remove contaminants from water. The team at Foam Fractionation Technologies developed a number of different test rigs to optimize the process and figure out the best way to restrict the foam to create a hyper concentrate. They then moved on to a commercial scale, constructing a larger scaler system.
00:25:00 In this video, the design and engineering team at a Brisbane office discuss how they could containerize and modularize systems to be ready for field applications. They also discussed the Pretreatment Process of Foam Fractionation and the subsequent Polishing. They showed a video of a full-scale PFS water treatment plant.
00:30:00 Foam fractionation is a technology that can be scaled to manage Co contaminants, such as hydrocarbons, in a water treatment process. This process is advantageous over other technologies, such as GAC and ionized resins, because it can strip contaminants out of solution, which improves the efficacy of the fractionation process.
00:35:00 The video discusses foam fractionation, which is a gross pollutant removal system. The process begins with pretreatment, which removes wet, sloppy foam from the first cut. Hyper concentrate is then drawn to a knockout drum and sent to the next hyper concentrator, which is in rapid mode with a vacuum head. Concentrations step down from 20 parts per billion to 4 or 500 parts per billion as the process moves through the four stages of growth. Vacuum distillation removes about 97% of free water, leaving 3% of the original volume. The final drawing phase removes the remaining liquor and contaminants. Overall, the process leaves a very tiny volume of highly concentrated PFS liquor along with a few other contaminants.
00:40:00 The presenter discusses the various benefits of foam fractionation, including its low power requirements and the ability to treat water to Australian drinking water standards.
00:45:00 The company offers water treatment systems that can be shipped to any location in the world, and can be set up quickly and effectively in an in-situ situation.
00:50:00 The presenter discusses the lab sandbox work and so on to develop zones of influence for foam fractionation, but points out that the technology has immense applications in terms of in-situ treatment. They did some work at a defense site where the initial concentrations in groundwater were 640 parts per billion. They went to the site in 2016 and dropped a vacuum head down an existing groundwater monitoring well, and the highest groundwater monitoring well had 640 micrograms per liter of pee Foss in it after 30 minutes. They removed a hundred and thirty thousand micrograms per liter of pee fussing, and the resultant pee Faust's at the bottom of the groundwater any lessened it was 110. The presenter didn't go down to below drinking water criteria because the groundwater table at that site is quite high about a meter and a half below the groundwater surface.
00:55:00 The presenter provides a brief overview of how foam fractionation technology can be used to remediate PFAS contamination. They note that while the technology is different than traditional soil vapor extraction (SVE), its effectiveness at removing PFAS concentrations below drinking water standards is similar. The presenter also discusses how the technology can be used to remediate high TDS waters.
