METHOD AND APPARATUS FOR COMBINED FILTRATION AND ANTI-MICROBIAL TREATMENT OF STORM WATER RESIDENT IN STORM WATER SYSTEMS

摘要

Bacterial discharge from a storm water system is substantially eradicated or at least greatly reduced by providing a filter having a filtration and anti-microbial medium, disposed in sump areas of the storm water system. The medium both removes hydrocarbons and kills bacteria in storm water that is retained in sump areas after a storm event. The filter is disposed in the retained water within the system, rather than being positioned merely as a pass-through filter, thereby increasing the contact time between the anti-microbial agent and the bacteria so that large amounts of bacteria are eradicated, and explosive bacterial growth within the sump areas is precluded prior to such bacteria being flushed from the system during the next storm event. The anti-microbial agent is adhered to, combined with, impregnated in, or otherwise joined to the filtration media. Filtration media that includes delustered synthetic fibers is a very efficient absorbent.
