Brief:
| The Ultra-Urban® Filter with Smart Sponge® Plus, 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. The Ultra-Urban Filter destroys bacteria as it captures oil, grease, trash and sediment from stormwater runoff before it enters the storm drain system. The Ultra-Urban Filter is ideal for municipal, industrial, and construction applications. The filter comes in 2 standard designs, one a modular unit geared toward curb openings (CO), and the other, a single unit designed for typical drop in drains (DI). The Ultra-Urban Filter is designed for use in storm drains to treat water contaminated with bacteria, oil, grease, sediment, and debris. Trash and sediment accumulate in the upper basket chamber, oil and grease are captured in the filtration media, while bacteria are destroyed as they pass through the media. Teh vendor claims that field tests have proven that the proprietary Smart Sponge filtration media will remove up to 95% of the oil and grease in stormwater runoff - from low concentrations typical of residential areas to high levels associated with illegal dumping of used motor oil. The oil will bond with the Smart Sponge and become permanently encapsulated, eliminating the possibility of leaching or leaking back into the environment.
Smart Sponge Plus filtration media features a proprietary antimicrobial agent chemically and permanently bound to the Smart Sponge polymer surface and therefore does not leach or leak, avoiding any downstream toxicity issues. The antimicrobial mechanism is based on the patented agent's interaction with the microorganism cell membrane, causing microorganism disruption, but no chemical or physical change in the agent. Antimicrobial activity does not reduce the agent capability or cause its depletion and, therefore, maintains long-term effectiveness. Additionally, the hydrocarbon absorption capability is not inhibited by the antimicrobial agent. Consistent positive reduction in microbial concentration has been realized in laboratory settings and field testing sites in the United States. Microbial reduction efficiency will vary depending on colony size, flow rates and site specific conditions. |
