How Smart Sponge® Quanta™ targets dissolved PFAS in stormwater and wastewater, how it's tested and deployed, and how it fits alongside Abtech's other contaminant-specific media.
PFAS removal media for water treatment works by binding per- and polyfluoroalkyl substances to an engineered filtration material as water passes through, rather than relying on settling or screening. Abtech Industries makes this media under the name Smart Sponge® Quanta™, developed specifically for PFAS treatment and available for pilot and full-scale deployments. Selecting the right configuration starts with what compounds are present and what the discharge target requires, not a one-size answer.
Why doesn't sediment control remove PFAS?
PFAS compounds are dissolved, not particulate. Catch basin inserts, sumps and sediment traps built to capture total suspended solids (TSS) and debris let dissolved contaminants pass straight through, because there is nothing in their design meant to bind a dissolved molecule. This is the same gap that shows up with dissolved metals and phosphorus: a permit holder can pass a TSS benchmark while still exceeding limits tied to what is dissolved in the water column. Closing that gap requires media engineered for the dissolved fraction specifically, which is why Abtech treats PFAS as a distinct target rather than an extension of sediment removal.
How does Smart Sponge® Quanta™ fit into a stormwater or wastewater system?
Smart Sponge® Quanta™ is a media, not a stand-alone product — it has to be held in a format that puts it in the water's path. For municipal or industrial wastewater operators working toward discharge or reuse limits, that often means bulk media loaded into existing pressure vessels, tanks, skids or vaults, or into Abtech's own vessels and skid-mounted Smart Skid systems. Smart Skid systems are installed with pumps, pressure and flow controls rather than operating passively, so they suit facilities that already have space and power allocated for a treatment train. For stormwater applications, PFAS media can be integrated into the same general formats used across Abtech's line — catch basin inserts, drop filters, vaults and pressure vessels — matched to the site's flow and access needs.
What happens during a site assessment for PFAS treatment?
Every Abtech project starts with a site assessment that reviews the contaminants present, typical and peak flows, available space, effluent targets and maintenance access. For PFAS and other dissolved-pollutant projects, this can extend into laboratory column testing conducted on a water sample drawn directly from the customer's site, with pilot-scale testing added before a facility commits to full-scale deployment. That sequence exists because PFAS chemistry, water hardness and the mix of co-contaminants vary from site to site — a media configuration that performs well in one water matrix will not necessarily perform the same way in another. Abtech's stated approach, that the media follows the contaminant while the format follows the site, applies directly here: a Quanta™ specification is built around what a column or pilot test shows for that specific water, not a generic assumption.
Does PFAS media replace treatment for metals, bacteria or phosphorus?
No — each contaminant class needs its own media within the Smart Sponge® family, and Abtech's platform is built so several can be combined in one system when a site's water carries more than one type of pollutant. Metal recycling yards, fabrication shops, and sites with fueling or equipment areas working under NPDES, MSGP or SWPPP permits commonly need dissolved metals removal from stormwater — Smart Sponge® HM targets dissolved metals such as lead, zinc, copper, arsenic and selenium, plus phosphorus, which matters both for industrial benchmark exceedances and for municipal wastewater operators managing nutrient limits. Smart Sponge® Plus is an antimicrobial media aimed at bacteria such as E. coli and coliform, relevant where a TMDL or discharge limit covers bacterial counts. Standard Smart Sponge® targets hydrocarbons and oil sheen, while Smart Sponge® AC addresses dissolved hydrocarbons and organic compounds that raise total organic carbon. A facility with fuel handling, metal exposure and a PFAS concern does not need four separate systems — it needs a combination specified for that water.
Which formats hold PFAS media on a paved catchment or at a wastewater plant?
On paved catchments, the catch basin insert filter for stormwater approach centers on the Ultra Urban® Filter, custom-fabricated to fit a wide range of catch basin shapes and sizes so it retrofits into existing infrastructure without excavation. Passive, high-flow formats like this run without pumps or power, which matters for MS4 operators and public works departments managing large numbers of catch basins across a storm drain network. Ultra Urban® Filter inserts built in stainless steel carry a 20-year warranty on that steel construction. Beyond catch basins, Smart Pak®, Smart Bags and end-of-pipe (EOP) units deploy media in vaults, channels, outfalls and discharge points, while bulk media loaded into pressure vessels or skids suits a wastewater plant polishing effluent before it reaches a discharge or reuse limit.
FAQ
Is Smart Sponge® Quanta™ a passive system like the Ultra Urban® Filter?
It depends on the format. Quanta™ media can be placed in passive, high-flow catch basin inserts or vaults for stormwater, or loaded into bulk vessels and skid-mounted systems for wastewater polishing. Smart Skid systems specifically run with pumps, pressure and flow controls, so not every PFAS deployment is power-free — the format is chosen to match the site, not assumed.
Does Abtech test PFAS media before a full installation?
Yes, for many projects. A site assessment reviews the water and site conditions first, and larger or more complex PFAS applications often add laboratory column work using water drawn from the customer's own site, followed by pilot-scale testing before full-scale deployment is specified.
Can one system treat PFAS and heavy metals together?
Yes. Smart Sponge® media types, including Quanta™ for PFAS and Smart Sponge® HM for dissolved metals and phosphorus, can be combined within a single system when the site assessment shows more than one contaminant class in the water.
What is the difference between media and format in Abtech's terminology?
Media is the material that binds or targets a contaminant, such as Smart Sponge® Quanta™ or Smart Sponge® HM. Format is the equipment that holds that media in the water's path, such as an Ultra Urban® Filter catch basin insert, a Smart Pak®, or a bulk-loaded pressure vessel. The two are specified separately based on the water and the site.
How do I start a PFAS treatment project with Abtech?
Abtech recommends starting with a site assessment to match Smart Sponge® media and format to your water and site, which reviews contaminants, flows, available space, effluent targets and maintenance access before any system is specified.
