Bulk Smart Sponge® media loads into existing vaults, pressure vessels, tanks and skids to target dissolved metals, phosphorus, bacteria, hydrocarbons and PFAS without a full system replacement.
Bulk filtration media for stormwater vaults and pressure vessels lets a facility load engineered treatment material directly into infrastructure it already owns, rather than replacing the vault or vessel outright. Abtech Industries supplies Bulk Smart Sponge® media sized for existing pressure vessels, skids, tanks and vaults, so the contaminant load in the water — not the shape of the container — drives the media selection.
Why Treat With Bulk Media Instead of a New System?
Many MS4 operators, industrial dischargers and wastewater facilities already have vaults, tanks or pressure vessels installed as part of a stormwater or process water line. When that infrastructure is sound but the treatment inside it is outdated or absent, replacing the media inside the vessel is often more direct than replacing the vessel itself. Abtech's approach follows a stated principle: the media follows the contaminant, the format follows the site. A vault built for sediment capture, for example, may need a different media charge once a permit adds a dissolved-metals or bacteria limit — the vault stays, the media inside it changes.
Which Smart Sponge® Media Fits the Contaminant?
Bulk loading only works if the media matches what is actually in the water. Abtech's media family is organized by contaminant class rather than by a single generic formulation:
- Smart Sponge® HM targets dissolved metals — including iron, copper, zinc, lead, arsenic and selenium — along with phosphorus, which matters for metal recycling yards, metal fabrication shops, junk yards and municipal wastewater facilities working toward a phosphorus discharge or reuse limit.
- Smart Sponge® Plus is an antimicrobial media for bacteria such as E. coli, fecal coliform and enterococcus, relevant to sites under a bacteria TMDL or receiving-water advisory.
- Smart Sponge® is a hydrophobic, oil-attracting media that binds hydrocarbons in runoff, industrial water and marine applications.
- Smart Sponge® AC addresses dissolved hydrocarbons and organic compounds that raise total organic carbon.
- Smart Sponge® Quanta™ is formulated for PFAS treatment, available for pilot and full-scale deployments.
Because a single vault or pressure vessel can face more than one pollutant class at once — a metal recycling site with both zinc and oil sheen, for instance — several of these media types can be combined within one vessel to address multiple treatment objectives at the same time. Which media, or combination of media, is right for a given vessel depends on the concentrations present, the water chemistry, and the effluent target the permit sets, not on a fixed formula, so a site assessment reviews these factors before any media is specified.
What About Sediment and Trash Ahead of the Vault?
Dissolved-pollutant treatment inside a vault or vessel works alongside upstream capture, not instead of it. Abtech's Ultra Urban® Filter catch basin insert is custom-fabricated to a wide range of basin shapes and sizes and is built to California's Full Trash Capture standard, so trash and debris, along with TSS, are addressed at the inlet before flow reaches downstream treatment. Sediment control alone, though, does not address dissolved metals, nutrients or bacteria that pass through in solution — which is the gap bulk media inside a vault or vessel is designed to close.
How Does This Fit Formats Like Smart Skid and Vessels?
Bulk Smart Sponge® media can be delivered loose for a customer's own tanks and vaults, or installed in Abtech-supplied vessels and the skid-mounted Smart Skid system. Vessels accommodate a range of flow rates and operating pressures and are built for straightforward media replacement when the charge is spent. Smart Skid systems are installed with pumps, pressure and flow controls — they are not passive, power-free units — which makes them suited to sites that need controlled flow through a pressure vessel rather than gravity-fed treatment. For sites without existing vessels, Smart Pak®, Smart Bags and EOP units offer flexible ways to place media in vaults, channels, outfalls and discharge points. Details on how each format holds the media are laid out on Abtech's filtration media deployment options and installation formats page.
What Permit Drivers Make Bulk Media the Right Fit?
Industrial facilities operating under NPDES, MSGP and SWPPP requirements often turn to bulk media after a benchmark exceedance for oil and grease, zinc, copper, lead or phosphorus triggers a documented corrective action. MS4 operators and public works departments look to vault-based treatment to reduce pollutant loads across storm drain systems feeding a TMDL-listed waterway. Municipal and industrial wastewater operators use bulk media, vessels or Smart Skid polishing to work toward discharge or reuse limits for phosphorus, metals, TOC or PFAS. State-level stormwater rules also change from time to time, which is one more reason permit holders periodically review whether an existing vault or vessel can be upgraded internally with a different media charge rather than replaced outright. Bulk media inside existing infrastructure is one best management practice among several that a facility's stormwater BMP plan may call on, chosen based on what the water carries and what the permit requires. A site assessment reviews contaminant concentrations, typical and peak flows, available space and effluent targets before any media or format is specified.
Frequently Asked Questions
Can bulk media be loaded into a vault we already own?
Yes. Bulk Smart Sponge® media is supplied in the quantity needed for integration into existing pressure vessels, skids, tanks and vaults, so the container generally does not need to be replaced to add or upgrade treatment.
Do we need lab testing before ordering bulk media?
A site assessment reviews contaminants, flows, space and effluent targets first. For wastewater applications and larger projects, Abtech can run laboratory column testing on a customer's own water sample and pilot testing before full-scale deployment.
Can one vault treat more than one contaminant?
Several Smart Sponge® media types can be combined within a single system when a site's water carries more than one pollutant class, such as dissolved metals alongside hydrocarbons.
Is a Smart Skid system passive like a catch basin insert?
No. Smart Skid systems are installed with pumps, pressure and flow controls to move water through the pressure vessel, unlike passive formats such as the Ultra Urban® Filter, which relies on gravity flow.
Does bulk media replace the need for sediment or trash capture?
No. Sediment and trash capture at the inlet, such as a Full Trash Capture-certified catch basin insert, addresses particulate load, while bulk media inside a downstream vault or vessel targets the dissolved fraction that sediment control does not remove.
