Ultra Urban Filter Styles to Fit Every Drain

• Curb Opening
• Drain Insert
• Customized Drain Insert

The Ultra-Urban® Filter with Smart Sponge® developed and manufactured by AbTech Industries, is an innovative low-cost BMP that helps meet NPDES requirements with effective filtration, efficient application, and low maintenance. It is a true water filter that ensures that the water flowing through the system is properly and completely treated. This solution is used to treat stormwater runoff for new or retrofitted sites by absorbing oil and grease and capturing trash and sediment. In addition, AbTech's Smart Sponge Plus® contains an antimicrobial agent that is effective in reducing coliform bacteria found in stormwater, industrial wastewater, and municipal wastewater. Smart Sponge® and Smart Sponge® Plus are comprehensive solutions geared at removing key contaminants and pollutants from stormwater runoff.

The Ultra-Urban Filter is ideal for municipal, industrial, and construction applications ensuring compliance with stormwater regulations. The filter comes in two standard designs; one a modular unit geared toward curb inlet openings, and the other, a single unit designed for typical drop-in catch basin drains.

• Municipal Stormwater Drains
• Shopping Center Parking Lot Drains
• Parking Structures
• Airport Tarmac Drains and Fuel Farms
• Commercial Fuel Distributor Facilities
• Commercial and/or Residential Developments
• Truck Stops

How it Works

The Ultra-Urban Filter, made of a high strength corrugated recycled content plastic, is designed for use in storm drains that experience oil and grease pollution accompanied by sediment and debris. Trash and sediment accumulate in the upper basket chamber while oil and grease are absorbed in the filtration media.

Proven Performance

Field and laboratory tests have confirmed the capability of the Smart Sponge to absorb, depending on the type of oil contaminant, up to three times its own weight and remove up to 95% of the hydrocarbons present in Stormwater runoff, typically in the range of 5 to 30 mg/liter (ppm). The captured oil is permanently bound within the Smart Sponge, eliminating leaching and allowing for easy disposal of the filtration media. Flow rates through the filters have been tested to exceed 500 gpm for the DI2020 series at installation. The Ultra-Urban Filter with Smart Sponge has also proven effective at removing 80% TSS (300 Micron).

Easy Installation

The Ultra-Urban Filter is easily installed. Installation time varies depending upon mounting devices selected. A single mounting bracket made of 16-gauge galvanized steel is required for the installation of the Curb Opening (CO) series. The Ultra-Urban Filter should not be installed where modules obstruct the drain pipe outlet. The size of the drain should allow room for stormwater overflow. The Drain Inlet (DI) series Ultra-Urban Filter will suspend from the drain into the catch basin through a structural plastic mount and funnel mechanism.

Low Maintenance

The Ultra-Urban Filter should be serviced as needed to remove sediment and debris, according to expected debris accumulation. The sediment and debris can be quickly vacuumed out of the modules through the opening of the drain with conventional maintenance equipment. For example, a curb inlet with four to five Ultra-Urban Filter modules can typically be serviced in 10 minutes or less. Under normal operating conditions the Ultra-Urban Filter should be replaced every 1-3 years.

Proven Technology

AbTech developed the Smart Sponge technology based on its proprietary blend of synthetic polymers aimed at removal of hydrocarbons and oil derivatives from surface water. AbTech's process creates a very porous structure (see Figure A) with hydrophobic and oleophilic characteristics capable of selectively removing hydrocarbons while allowing high flow through rates for water. As hydrocarbons are absorbed into its structure, the Smart Sponge® swells and maintains porosity and filtering capabilities.

Antimicrobial Solution

AbTech Industries has successfully deployed its patented antimicrobial technology, Smart Sponge Plus®, which features an antimicrobial agent chemically and permanently bound to the Smart Sponge® polymer surface. The antimicrobial mechanism is based on the patented agent's interaction with the microorganism cell membrane, causing the microorganism disruption – but no chemical or physical change in the agent. Antimicrobial activity does not reduce the agent's capability or cause its depletion and, therefore, maintains long-term effectiveness. Additionally, the hydrocarbon absorption capability is not inhibited. When properly installed and maintained, Smart Sponge® Plus provides a significant reduction in coliform bacteria. As with all AbTech products, field deployment and data generation projects are ongoing.
