Comparative Study on the Drying Process and Fractal Dimension of Sewage Sledge: Microwave and Air-Blast

Abstract:

A fractal model simulate the internal structure of the sludge, and on the model deduce that fractal dimension is D and the corresponding pore is r, the porosity is P. Determine the rate in the air-blast and microwave drying and calculate its different fractal dimension under different ages. The results showed that: the fractal dimension and its rate of water loss has a good correlation. Fractal dimension can describe a certain amount of sludge pore channels and internal cell rupture can cause that which would accelerate the evaporation of bound water. Microwave and the excessive energy of air-blast can be caused by temperature changes in the structure of the sludge that could change the structure of sludge.
