We analyzed the blanket dynamics in a fluidized bed using a simplified one-dimensional model. The model predicted that the distribution of the solids fraction, initially randomly distributed in the blanket, would firstly evolve to a wave-like distribution at a lower solids fraction. Then the blanket would compact itself to another uniform distribution at a higher solids fraction. Experimental works with synthetic raw water coagulated with PACl fluidized in a lab-scale fluidized bed confirmed the theoretical predictions. The solids flux plot was constructed with underdosed, optimal, and overdosed suspensions. The operating condition at which the effluent turbidity reached a minimum was indicated as the “optimal’ condition of the blanket system.application/pdf68592 bytesapplication/pdfzh-TW國立臺灣大學化學工程學系暨研究所泥毯穩定性調理模型Blanketstabilityconditioningmodelreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/9374/1/922214E002007.pdf
