How BioLargo’s Aqueous Electrostatic Concentration Solves PFAS Contamination
In this episode of Engineers for Communities, we spoke with Tanya Chandler and Sally Gutierrez from BioLargo about tackling one of today’s most critical environmental challenges: PFAS contamination. Known as “forever chemicals,” PFAS are widespread in U.S. water systems, posing serious risks to health and the environment. Tanya and Sally shared insights into the issue and groundbreaking solutions that can make a difference.
What Are PFAS and Why Do They Matter?
PFAS, or per- and polyfluoroalkyl substances, are chemical compounds found in everyday products and industrial processes. They don’t break down easily, contaminating water, soil, and even the human body. Sally noted that PFAS was detected in human blood over 15 years ago, with research confirming their harmful effects on health.
The EPA has set drinking water limits for six PFAS compounds—a necessary step—but dozens more are under study, meaning regulations will only tighten in the coming years.
BioLargo has developed a game-changing tool for tackling those nasty “forever chemicals” in our water. Their Aqueous Electrostatic Concentrator (AEC) isn’t just another filtration system – it’s a completely different approach to pulling PFAS out of water.
How It Works
So what makes this thing special? The AEC uses electrical fields to grab onto PFAS molecules floating in water. Think of it like a magnet that only attracts these specific chemicals. Once the system has a hold on them, it forces them through BioLargo’s special membrane. The clean water flows out one way, and all those harmful chemicals get concentrated separately.
I’ve seen plenty of water treatment systems, but this one’s actually pretty clever. Instead of just trying to filter everything or using tons of carbon to absorb contaminants, they’re specifically targeting PFAS with electricity. Their membrane is the secret sauce that keeps it all working.
Real-World Performance
The numbers look impressive – the AEC knocks out more than 99% of PFAS while water flows continuously through the system. For water utilities scrambling to meet tougher regulations, that’s huge.
What caught my attention was the operating cost – about 30 cents to treat 1,000 gallons. That’s a fraction of what most systems cost to run. For cash-strapped municipal water departments, this could be a lifesaver. They’re all facing PFAS cleanup with tight budgets, and traditional methods are breaking the bank.
Why It’s Better Than Current Options
The BioLargo system has some clear advantages:
It uses way less electricity than other methods. That’s not just good for the environment – it means lower monthly bills for whoever’s running it.
The biggest headache with most PFAS treatments is dealing with the concentrated waste afterward. This system produces much less toxic leftovers, which means fewer hazardous waste disposal headaches and costs.
It also uses less activated carbon overall. If you’ve priced carbon systems lately, you know why that matters.
The system is surprisingly compact too. I’ve seen treatment facilities where space is at a premium, and this could easily fit where other systems wouldn’t.
Getting to Market
The EPA has thrown some money behind this through their Small Business Innovation Research grants. That’s a good sign – the agency doesn’t fund technologies unless they show real promise.
As more communities discover their water contains PFAS and regulations get stricter, we’re going to need practical solutions. Traditional treatment methods cost too much and create disposal nightmares. If BioLargo can deliver on what this AEC system promises, they might have a real winner on their hands. The water treatment industry isn’t known for innovation, but this approach feels genuinely different from the usual options.
Conclusion
PFAS contamination is a complex challenge, but solutions like BioLargo’s AEC technology are making a real difference. By breaking the contamination cycle and addressing both drinking water and wastewater, communities can take meaningful steps toward cleaner, safer water systems.
