Abstract:
1. A method of separating water from a liquid comprising a combination of water and a dispersed or emulsified liquid hydrocarbon contaminant comprising: flowing the liquid into a liquid permeable conduit disposed within a collection vessel, said liquid-permeable conduit disposed within a cartridge containing fibers that carry liquid-absorbent particulate polymer particles capable of coalescing the hydrocarbon contaminant when said liquid flows radially outwardly through said fibers carrying said particulate polymer particles, and through a liquid-permeable cartridge cover, for collection in said vessel; flowing the liquid radially outwardly through the liquid-permeable cartridge cover, whereby water and coalesced hydrocarbons flow into said collection vessel; collecting the water and coalesced hydrocarbons in said collection vessel, removing the water from a lower portion of the collection vessel; and removing the coalesced liquid hydrocarbons from an upper portion of the collection vessel.
