| 20110034313 | CENTRIFUGE WITH HYDRAULIC DRIVE UNIT - A centrifuge includes a bowl. The bowl includes a cylindrical portion at a first end. The centrifuge further includes a hollow shaft. The hollow shaft is coaxial with the cylindrical portion and extends through at least the first end. The centrifuge also includes a hydraulic drive unit coupled to the cylindrical portion and configured to rotate the cylindrical portion. The hollow shaft and the cylindrical portion are rotatably coupled to each other. | 02-10-2011 |
| 20100196199 | SYSTEM AND METHOD FOR TREATMENT OF PATHOGENS IN DRIED SEWAGE SLUDGE - A method and system for treating biosolid material having pathogens, the method including: introducing dried biosolid material into a pathogen treatment vessel; monitoring an actual temperature of the dried biosolid material in the treatment vessel; determining a desired residence time of the biosolid material in the treatment vessel; determining a desired minimum temperature of the dried biosolid material in the treatment vessel, wherein the minimum temperature is based on the desired determined residence time of the biosolid material in the treatment vessel; passing the dried biosolid material through the treatment vessel such that the actual residence time of the biosolid material in the treatment vessel is at least as long as the determined residence time; applying heat from a hot fluid to the dried biosolid material in the treatment vessel, if the actual temperature of the biosolid material is lower than the minimum temperature, and reducing pathogens in the biosolid material by maintaining the biosolid material in the treatment vessel for at least the determined residence time while the actual temperature is at least as hot as the minimum temperature. | 08-05-2010 |
| 20100120600 | VIBRATING CENTRIFUGE - A vibrating centrifuge includes a housing; a basket rotatably supported by the housing; a main drive motor operatively connected to the basket to rotate the basket; a vibration transfer shaft operatively connected to the basket at a first end of the vibration transfer shaft to vibrate the basket; and at least one vibration motor resiliently connected to the housing and operatively connected to the vibration transfer shaft at a second end of the vibration transfer shaft. A vibration drive for a centrifuge including a basket rotatably supported in a housing includes a vibration transfer shaft operatively connected to the basket at a first end of the vibration transfer shaft; and at least one vibration motor connected to a mount, the mount being resiliently connectable to the housing, the vibration transfer shaft being connected to the mount at a second end of the vibration transfer shaft. | 05-13-2010 |
