The Ultra-Urban® Filter
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 moderate maintenance.Features
- Absorbs oil and grease
- Captures trash and sediment from stormwater runoff before it enters the storm drain system.
- Ideal for municipal, industrial, and construction applications
- Filter comes in two standard designs;
modular unit geared toward curb inlet openings (CO)
single unit designed for typical drop-in (DI) catch basin drains- Made of a high strength corrugated recycled content plastic
- 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.
Performance
- Field and laboratory tests have confirmed the capability of the Smart Sponge to absorb up to three times its own weight
- Able to remove up to 99% of the hydrocarbons present in stormwater runoff, typically in the range of 5 to 30 mg/liter (ppm)
- Captured oil is permanently bound within the Smart Sponge, eliminating leaching and allowing for easy disposal of the filtration media
- Flow rates through the CO1414 filters exceed 200 gpm. Flow rates through the DI2020 series filters exceed 500 gpm
Installation
- Easily installed
- 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.
- Size of the drain should allow room for stormwater overflow
- The Drop-In (DI) series Ultra-Urban Filter will suspend from the drain into the catch basin through a structural plastic mount and funnel mechanism.
Maintenance
- Filter should be serviced as needed to remove sediment and debris according to expected debris accumulation. Quarterly maintenance is recommended.
- Sediment and debris can be quickly vacuumed out of the modules through the opening of the drain with conventional maintenance equipment.
- Curb inlet with four to five Ultra-Urban Filter modules can be typically serviced in 10 minutes or less.
- Under normal operating conditions the Ultra-Urban Filter should be replaced every 1-3 years.
Applications
- Ultra-Urban® Filter is an ideal solution for new or existing applications.
- Examples of the filters current deployment are:
- 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
