Breakthrough Filtration Technology Heralds New Era in PFAS Removal
A groundbreaking new filtration technology developed by researchers at Rice University has the potential to revolutionize the removal of per- and polyfluoroalkyl substances (PFAS), also known as "forever chemicals." The innovation, which utilizes a layered double hydroxide material made from copper and aluminum, can absorb long-chain PFAS up to 100 times faster than existing filtration systems.
The technology works by attracting and concentrating the chemicals at high levels, making it possible to destroy them without high temperatures. This non-thermal process involves soaking up and concentrating PFAS at high levels, which renders them useless for disposal in hazardous waste facilities or destruction through thermal processes.
According to Michael Wong, director of Rice's Water Institute, a leading Pfas research center, the new material is a significant advancement in the field of PFAS research. "This material is going to be important for the direction of research on Pfas destruction in general," he said.
The LDH material is positively charged and attracts negatively charged long-chain PFAS, which are then trapped by calcium ions within the material. The resulting calcium-fluorine compound is safe and can be disposed of in a landfill, rendering the original PFAS harmless.
Wong notes that this technology has several advantages over existing methods, including its high absorption rate, recyclability, and compatibility with existing filtration infrastructure. This could significantly reduce costs associated with implementing new PFAS removal systems.
However, experts caution that while this breakthrough is promising, further research and testing are needed to ensure the technology's scalability and effectiveness in real-world conditions. Laura Orlando, a Pfas researcher at Just Zero, notes that "the processes are so complex in real-world conditions" and that occupational safety, regulations, and permitting will need to be carefully considered.
Despite these challenges, Wong remains optimistic about the potential of this technology to address the PFAS crisis. As he puts it, "we're going to need as many technologies as we can possibly find to deal with Pfas in drinking water."

! I mean, 100 times faster than existing tech is a HUGE win 
. And the fact that it's non-thermal and doesn't require high temps is super important – we need all the help we can get in destroying these chemicals safely 
. I'm curious to see how this will play out in real-world conditions, but if it can reduce costs and make existing filtration systems more compatible, that's a major win for the environment 
!
This is a step in the right direction for removing those toxic chemicals from our water supply 
At least now they've found something that can get rid of PFAS without having to heat it up, which is a major plus 
️ It's good to see researchers working on this and not just talking about it 
! I mean, think about it - no more 'forever chemicals' ruining our water supply 
. And it's not just fast, but also recyclable & cost-effective 
. Of course, we gotta test it in real-world conditions to make sure it works, but this gives me hope that one day our water will be pure and safe for our kids 
.
OMG I cant believe its finally happening!! This new filtration tech is literally the game changer for PFAS removal I mean think about it if this tech can absorb 100 times faster than existing ones just imagine the impact on our drinking water 
and environment Its like a dream come true that we might finally be able to eradicate these toxic chemicals from our lives 
Plus recyclability and compatibility with existing filtration infrastructure is a total win points for this tech If it can make PFAS removal more efficient and cost-effective then we should definitely be excited about this 
. It's crazy to me how much more efficient this technology is compared to what we've been using before. And the fact that it's recyclable and compatible with existing infrastructure? That's a major win 
. Of course, there are still some hurdles to overcome, but I'm hoping that this tech can be scaled up and used to make a real difference in the fight against PFAS. We're going to need all the help we can get, especially when it comes to drinking water safety 
. That's like a total game-changer because it makes the destruction process way safer and more effective.
. But overall, I think this is a major step forward in tackling the PFAS crisis 
the fact that it can destroy them without high temps is major 
. but Laura Orlando's caution is valid too... gotta test it in real-world conditions before we start implementing on a massive scale 
.
. But I think this tech has a lot of potential to make a real difference in our water infrastructure 
. If this tech can help make our drinking water safer, that's a huge win in my book 
. I just wish more people were celebrating this breakthrough instead of throwing shade 
. Anyway, keep an eye on this one - it could be big 
️!
.
.
️. We need to make sure we're prioritizing those aspects or this whole thing could blow up in our faces 
.
and then someone comes up with a magic filter that can just absorb them super fast 
like copper and aluminum are the ultimate superhero duo
