Abstract:
1. 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; 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.
