Washing the sludge reduced the total ash content to between 10.7% and 19.31% and increased the concentration of glucose, xylose and lignin.
WebbIn this study, the continuous moisture distribution in waste activated sludge is constructed on the basis of the combined thermal gravimetry analysis (TGA) and differential thermal analysis (DTA). The water-solid bond strength is considered here to be an adequate classification index.
In the United States, the following classes of sewage sludge after treatment are defined: Class A sludge is typically dried and pasteurized, and is also known as "exceptional" quality. Class B includes all sludge not classified as Class A. Class B sludge is typically "undigested" and is volatile.
