<description><![CDATA[The present processing apparatus blocks off such a portion of a flow of a plating solution ( 17 ) that is other than a vicinity of a liquid surface, by using a first partition plate ( 15 ) whose lower end is in close contact with a bottom of a plating tank ( 11 ) and whose upper end is at a position lower than a liquid surface. Therefore, the plating solution ( 17 ) flowing at the bottom of the plating tank ( 11 ) flows upwards along the first partition plate ( 15 ). At this time, heavy foreign substances do not tend to follow such an upward movement of the plating solution ( 17 ), and therefore sink and accumulate in a vicinity of the lower end of the first partition plate ( 15 ), so as not to flow into a downstream side of the plate. With this arrangement, the present processing apparatus can remove the heavy foreign substances from the plating solution ( 17 ) without relying solely on a filter of a circulation pipe ( 10 ).]]></description>

<description><![CDATA[A filter system for receiving an oil-in-water emulsion contaminated with an emulsified contaminant oil, and separating the emulsified contaminant oil from the oil-in-water emulsion includes a filter media for receiving the oil-in-water emulsion and emulsified contaminant oil, having an inner filter element formed from a 95 percent single pass efficiency 48 micron (5 micron nominal) filtering material of needle punch polypropylene felt, an outer filter element formed from a 95 percent single pass efficiency 19 micron absolute filtering material of a polypropylene microfiber material and a porous spunbond polypropylene sandwiching the outer filter media. The filter element de-emulsifies the emulsified contaminant oil from the oil-in-water emulsion into the contaminant oil and the oil-in-water emulsion, separates the de-emulsified contaminant oil from the oil-in-water emulsion, coalesces the separated contaminant oil and passes both the coalesced de-emulsified contaminant oil and the oil-in-water emulsion. A first tank supports the filter element and is further configured to hold a quantity of the separated coalesced contaminant oil and the oil-in-water emulsion. The first tank has an overflow passing to a second tank. The second tank has an oil separation assembly for removing the oil-in-water emulsion from the contaminant oil and passing the oil-in-water emulsion therefrom. A method for separating the emulsified contaminant oil from the oil-in-water emulsion and recovering the oil-in-water emulsion is also disclosed.]]></description>

<description><![CDATA[This invention is directed to systems and methods for removing lipids from a fluid or from lipid-containing organisms from a fluid, such as plasma. These systems combine a fluid with at least one extraction solvent, which causes the lipids to separate from the fluid or from the lipid-containing organisms. The separated lipids are removed from the fluid. The at least one extraction solvent is removed from the fluid or at least reduced to a concentration enabling the fluid to be administered to a patient without undesirable consequences. Once the fluid has been processed, the fluid may be administered to a patient who donated the fluid or to a different patient for therapy.]]></description>

<title><![CDATA[Waste extraction system]]></title>
<link>http://www.freepatentsonline.com/7363878.html</link>
<description><![CDATA[A waste extraction system ( 10 ) for an aquaculture tank ( 12 ) includes a first conduit ( 18 ) having a first end ( 20 ) and a distant second end, with a second conduit ( 22 ) disposed within the conduit ( 18 ). The second conduit ( 22 ) has a first end ( 24 ) which is co-terminus with the end ( 20 ) of the first conduit ( 18 ). A plate ( 26 ) extends transversely across the ends ( 20, 24 ) and laterally of the first conduit ( 18 ). An axial hole ( 28 ) is formed in the plate ( 26 ) to provide fluid communication with the second conduit ( 22 ), but the plate ( 26 ) otherwise closes off or seals the end ( 20 ) of the first conduit ( 18 ). Legs ( 30 ) are formed on an underside of the plate ( 26 ) to space the plate ( 26 ) from a bottom wall ( 16 ) of the tank ( 12 ). Apertures ( 34 ) are formed in the conduit ( 18 ) near its first end ( 20 ) to allow water to flow into a flow chamber ( 36 ) created between an inner surface of the conduit ( 18 ) and an outer surface of the conduit ( 22 ). The conduits ( 18, 20 ) exit the tank ( 12 ) at a location ( 38 ) which is at least partially below the water level ( 40 ) of the tank ( 12 ). A circular flow of water is generated in the tank ( 12 ) by having a water inlet manifold directing that allows incoming water to flow tangentially to an inside surface of a side wall ( 14 ) of the tank ( 12 ). By continually pumping water into the tank ( 12 ) while maintaining the water level ( 40 ), water is drawn from above the plate ( 26 ) through the apertures ( 34 ) in the first conduit ( 18 ) into the flow chamber ( 36 ) thereby creating a general upflow of water. Solid particulate material collects by action of centripetal force into a region beneath the plate ( 26 ) where it is entrained in water and flows up through the axial hole ( 28 ) in the plate ( 26 ) into the second conduit ( 22 ) and out of the tank ( 12 ).]]></description>
