Process For Treating Septage
US Patent:
6558550, May 6, 2003
Filed:
Apr 26, 2002
Appl. No.:
10/134077
Inventors:
Robert J. Kelly - Brockton MA 02301
International Classification:
C02F 332
US Classification:
210609, 210615, 210754, 210150, 210175, 210173
Abstract:
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.
Process For Treating Septage To Extract A Bio-Fuel
US Patent:
2007005, Mar 15, 2007
Filed:
Jul 5, 2006
Appl. No.:
11/481217
Inventors:
Robert Kelly - Brockton MA, US
International Classification:
C02F 11/00
US Classification:
210609000, 210631000, 210202000, 210770000
Abstract:
A process for the treatment of septage, particularly grease trap waste, is disclosed. The inventive process converts septage into sludge usable as a bio-fuel. The conversion of the septage makes it desirable as an alternative fuel source, as the sludge has a high BTU value due to the large percentage of grease in the septage.
