Patent ID: 8323506

Claim:
A method of filtering hydrocarbon contaminated water in an area having a drain opening, said method comprising the steps of: inserting a filtration device into said drain opening; said filtration device including: a housing; a filtration compartment within said housing comprising at least one porous tube extending from a top inner surface of said housing into said filtration compartment; a treatment compartment located below said filtration compartment within said housing containing a hydrocarbon absorption media capable of absorbing hydrocarbons, said media comprising a material selected from the group consisting of styrene, pentadiene, cyclopentadiene, butylene, ethylene, isoprene, butadiene, propylene and mixtures thereof, and a filtration enabler; and a bypass system within said housing and traversing said filtration compartment and said treatment compartment flowing said hydrocarbon contaminated water into said filtration device; filtering debris from said hydrocarbon contaminated water as said hydrocarbon contaminated water passes through said filtering compartment of said filtration device; removing hydrocarbons in the hydrocarbon contaminated water as said hydrocarbon contaminated water passes through said treatment compartment of said filtration device such that hydrocarbon contaminated water flowing from said treatment compartment is rendered substantially hydrocarbon-free; and controlling an overflow of said hydrocarbon contaminated water within a containment area, by permitting any overflow to bypass said filtration compartment and said treatment compartment by entering said bypass system.
