Patent number: 6730231Abstract: A device for separating the constituents of a multi-constituent material includes a substantially cylindrical plasma chamber and two, axially opposed plasma injectors. The injectors convert the multi-constituent material into a multi-species plasma and inject the multi-species plasma into a core portion of the plasma chamber.

Publication number: 20030121856Abstract: The invention provides methods and an apparatus for more efficiently and economically producing purified water from sea water or some other salty or brackish water source. The efficiency is derived from the co-location with a power plant or other thermal generating source that will heat the feed water. Reverse osmosis membrane filtration systems work optimally when the feed water is at certain higher temperature, where that temperature is typically higher than the feed water at ambient temperatures. By using the heated sea water as the byproduct of the power plant electricity generating process and if necessary mixing it with ambient temperature sea water, if needed to lower the water temperature, and using this feed water with a higher temperature than ambient water temperature, the efficiency of the reverse osmosis system can be increased.Type: ApplicationFiled: December 30, 2002Publication date: July 3, 2003Inventor: Nikolay Voutchkov

Patent number: 6558550Abstract: A process and apparatus for the treatment of septage, particularly grease trap waste, is disclosed. The inventive process will convert the septage into Biosolids (sludge) and water dischargeable to the environment. The treated septage achieves pathogen reduction, and reduced vector attraction. Treatment of septage by pasteurization causes the destruction of harmful pathogens. Pasteurization of septage having high water content provides for even temperature elevation and distribution of heat within the thermal mass of the septage allowing for consistent pathogen destruction. An alkaline compound is utilized to form a filter cake from the solids fraction of the pasteurized septage preventing vector attraction, while producing a beneficial bio-solid. The liquid fraction of the septage is treated by biological process allowing for its discharge into the environment.Type: GrantFiled: April 26, 2002Date of Patent: May 6, 2003Inventor: Robert J.

Publication number: 20030066793Abstract: A collector for use in removing metal ions from a plasma in a vacuum chamber includes a collector plate that is mounted inside the chamber and formed with an internal cooling channel. An injector introduces a dissociated salt into the chamber with a first throughput value, and it introduces a plasma including metal ions into the chamber with a lower second throughput value. A pump is used to pump a liquid coolant through the cooling channel to maintain the collector plate at a temperature that forms a portion of the salt as a protective layer on the collector plate, and causes the salt to thereafter deposit on the layer in a molten condition at a faster rate than evaporation therefrom to trap metal ions therein. The trapped metal ions are then removed with the molten salt from the chamber.Type: ApplicationFiled: July 11, 2001Publication date: April 10, 2003Inventors: Brian P. Cluggish, Stephen F.

Patent number: 6521133Abstract: The present invention pertains to a system for thermal disinfection of sludge with the aim of pathogen reduction. Such thermal sludge treatment systems require a certain minimum detention time t dependent on the temperature T of the heated sludge. The system according to the present invention is a continuous flow system. The system includes means for continuous sludge heating. The heated sludge flows continuously through at least one chamber, whereby the flow through the chamber has a substantially vertical direction. The mean residence time t2 of the sludge between entering the chamber and leaving the chamber is minimum 2 times the time period t required by regulations for conventional batch systems. The ratio of the flow path length of the flow through the chamber or chambers to the hydraulic diameter of the vertical flow through the chamber or chambers l/d is at least 3:1. The higher the ratio t2/t, the smaller can be the required ratio l/d. The relationship is: l/d*t2/t>8.Type: GrantFiled: August 7, 2000Date of Patent: February 18, 2003Assignee: Roediger Pittsburgh, Inc.Inventor: Markus Roediger
