ABSTRACT:
A polishing filter having the capabilities for removing small solids and hydrocarbons present within a liquid flow is a filtration device to be used either in conjunction with processes already in existence or as a stand-alone unit. The polishing filter can be used for marine, commercial or industrial activities. Small solids will be discriminated hi( size by a removable and replaceable bag filter. Residing inside the bag filter is the polishing filter bonding media, a hydrocarbon encapsulation agent used to separate and bond emulsified and dissolved oils. This bonding media is contained inside a porous membrane bag which is also removable and replaceable. The .addition of this device to already existing equipment utilized by ocean vessels and commercial and industrial activities will enhance the decontamination process and assist in compliance with local, national and international clean water laws for effluent from ships and shore-based activities.
