Supplemental bilge filtration system |
摘要 |
A discharge water system for the bilge of a boat includes a primary bilge discharge system and a supplemental bilge filtration system. The primary discharge system includes a pump operable when the fluid in the bilge collects above a predetermined level in the boat to discharge bilge water overboard. The supplemental system includes a filter assembly with filter media for removing hydrocarbons in bilge water passing through the media; and a pump operable when the water in the bilge collects to a selected level below the operating level "L" of the primary pump to pump bilge water to the filter assembly and then to discharge the essentially hydrocarbon-free bilge water overboard. The filter assembly includes primary secondary filter cartridge, both of which include hydrocarbon-absorbing media, and are connected in series. A pressure sensor and remote indicating device provide an indication of the primary filter cartridge becoming spent.
