Abstract:
1. A system for removing hydrocarbons from hydrocarbon contaminated water, said system comprising: a sump for collecting hydrocarbon contaminated water; a pump located in said sump, said sump collecting hydrocarbon contaminated water, said pump having a float switch operating to automatically start said pump when said sump has collected a predetermined amount of contaminated water; a water treatment vessel at a higher level than said sump, including: a pipe fluidically connecting an outlet of said pump to said inlet of said water treatment vessel; wherein, said pump pumps hydrocarbon contaminated water into said water treatment vessel and through said filtration cartridge where hydrocarbons are absorbed, while purified water is allowed to exit said vessel through said discharge pipe, whereupon the pressure switch will act to cease operation of said pump upon reaching a predetermined pressure caused by accumulation of hydrocarbons in said filtration cartridge, while said overflow pipe will return hydrocarbon contaminated water to said sump when the level of liquid within said vessel exceeds a predetermined level.
