We all know the effects that storm water runoff has on our local watersheds. When the rain water fills up the gutters along the street it carries with it pollutants right into streams, lakes and our oceans. These pollutants are extremely damaging to the wildlife and flora that make those watersheds home.
Abtech Industires a Scottsdale, AZ company has a solution to help fight the nonpoint pollution at the curb.
AbTech’s Smart Sponge┬«Plus technology, the only non-toxic, fully recyclable filtration system that destroys bacteria at the street level.
The presence of bacteria in stormwater is a serious problem and poses significant health risks that increasingly result in the contamination of water bodies. Water quality standards for bacteria count are very strictly monitored in most coastal areas and small increases in bacteria counts can trigger beach closures. Nearly 20,000 beach closings and advisories were reported in 2007 alone. The greatest opportunity to reduce this bacterial count is during rain events through the control and treatment of stormwater runoff. This can be achieved either expensively, utilizing heavy equipment, ultraviolet light or chlorine treatment (all of which may be cost prohibitive to most municipalities); or, inexpensively thru the introduction of filtration products such as AbTech’s Ultra-Urban┬«Filter with Smart Sponge┬«Plus located in stormwater drain entrances.
This product is being used in several municipalities around the US and is also ideal for use in large commercial situations like airports, marinas, etc. According to AbTech’s site their technology is being used in 36 different states.
Smart Sponge┬« fully encapsulates recovered oil, resulting in a substantially more effective response that prevents absorbed oil from leaching. It is also capable of removing low levels of oil from water, thereby successfully removing sheen. In addition, the Smart Sponge┬« remains buoyant in calm or agitated water, permitting it to remain in place until fully saturated and resulting in no wasted product. Once oil is absorbed, the Smart Sponge┬« transforms the pollutants into a stable solid for easy recycling, providing a closed-loop solution to water pollution.
This seems like a no brainer, install a filter at the collection point of the system and stop the contaminants from entering the system. They are expected to be replaced every 1-3 years depending on just how much of a filtering load they have had to deal with. The spent Smart Sponge has been used as a fuel in waste to energy facilities as well as a fuel in cement kilns.
