Abstract

The viscosity of sludge not only affects its transport properties, but also the drying efficiency. In the paper, the sludge property of apparent viscosity was studied with the different types of sludge moistureÿcontent ofÿsludge and temperature with the help of NDJ series digital viscometer. The results show that the different content of organic matter between municipal sludge and dyeing sludge makes the viscosity of municipal sludge much larger than dyeing sludge's, and the difference increases with the decrease of respective moisture content of the two kinds of sludge. The apparent viscosity of sludge shows exponential growth in the form of with the decrease of the moisture content, and coefficient of g is approximately the constant value under different temperatures and different moisture content .In addition, the values of municipal sludge and dyeing sludge are -49.64 and -25.10 respectively. In the meanwhile, indicating that the models of coefficient f of municipal sludge and dyeing sludge are accordance with ExpDec1 model and Log3P1 model respectively, and finally model equations are obtained between apparent viscosity of sludge and moisture content and temperature
