Smart Sponge® Media FAQs

Why is Smart Sponge media considered cost-effective?


  • Smaller footprint
  • Low headloss & high absorption capacity
  • Long life-cycle
  • Adaptable into existing infrastructure




How do you dispose of spent media?


  • Non-hazardous for landfill disposal
  • Viable alternative energy source for cement kilns or waste energy facilities




How long does your media last?


  1. Varies, typically 2-3 years
  2. Inspect media while servicing products
  3. Media change-out is dependent on contaminant loading




Does your media have approvals?


Smart Sponge Plus:

  • EPA Registered
  • California DPR
  • Registered in most states




Can I target more than one contaminant.


Yes, Smart Vaults can be supplied with different Smart Sponge variants which can target, for example, bacteria and heavy metals. It is more difficult to do with UUF given the volume of media is limited but Smart Sponge Plus, for example, will remove bacteria, hydrocarbons and particulate forms of nutrients and heavy metals.




How can I tell when Smart Sponge is spent?


Visually by how much debris is captured and if blinding is occurring. And, by its color and weight.




Does the latest Smart Sponge that works with emerging contaminants remove PFOA and PFOS?


Unknown at this time. AbTech is developing media for PFOS remediation.





Product FAQs

How do you appropriately size a UUF for a drop-in catch basin?


The size of the catch basin determines the size of UUF.




How do you appropriately size a UUF for a curb-opening catch basin?


Sized to treat a specific water quality flow and to fit within the existing curb-opening.




What are your warranty terms?


  • All our products come with a standard 12-month warranty.
    • Our stainless-steel UUF Chester series come with a 20-year warranty.




Do you provide engineered solutions?


Yes, our experienced engineering staff is capable of doing full turn-key solutions to standard engineered process designs.




Do your products have approvals?


  • Utra-Urban® Filter (UUF) Chester: CA Water Board Certified for FTC
    • UUF TSS: NJCAT Verification and FTC




What contaminants do your solutions target?


Hydrocarbons, Heavy metals, Bacteria, Emerging contaminants, Nutrients, TSS (including trash & debris).

    • Visually inspect regularly and replace when spent




Can you use your products for industrial process water?


Yes, that is the most common application for our Smart Drum filters.




How long does a DI or CO UUF maintenance take?


Depending on set-up time, about 10 to 15 minutes.




How long does maintenance take for Smart Vault?


Different Smart vault sizes, the amount of media and volume of liquids and solids will determine the time needed to clean the vault and replace the media. There is also set-up and tear down time that differs depending on the location and traffic to be managed. Depending on the access method smart vault are classified as confined space entry. Depending on vault size the amount of media, volumes of trash sediment and debris captured, clean out time can vary significantly. There is also prep and tear down time depending on location of installation. For reference, a 4-ft by 6-ft vault with 1-ft of media depth can be cleaned and media replaced in less than an hour.




What is the difference between UUF CO and DI?


The UUF “Curb Opening” or CO is a filter sleeve designed to fit into a catch basin that is used to accept surface runoff through a curb opening. The UUF “Drain Insert” or DI is a filter sleeve designed to fit into a catch basin that is used to accept surface flow directly from above through an inlet grate. The sleeves are very similar but the DI is suspended from a collar that fits into the frame. The CO sleeve is attached to a bracket that is attached to the side of the catch basin. Once attached to the bracket, the sleeve is positioned directly beneath the curb opening.




What is the difference between UUF TSS and Chester?


The primary difference between an UUF Chester and UUF TSS is that the TSS models do not include Smart Pak® media and are designed, tested and verified (by NJCAT) to remove, via physically screening, trash, debris and any particulates larger than about 53 microns. Many contaminants, like nutrients and heavy metals, are removed as a result of capturing this particulate material. The UUF Chester has a slightly different enclosure that will capture any particle greater than 5 mm and contains Smart Pak filtration media that is used to target fine particulate, trash, debris as well as sorption of hydrocarbons, metals and phosphates.




What certifications/verifications do your products and media have?


- Smart Sponge® Plus - EPA registration as well as many states - UUF TSS - NJCAT verification - All UUF's - PADEP, CA Water Board registration for Full Trash Capture
