【Abstract】 The fractal dimension of the deposition porosity structure in different conditions has been obtained by the photographing deposition surface in the fiber bundle as the filter media with the sweep electron microscope and image analysis.The relationship between the fractal dimension and the filtration processes and the effect of the coagulant in the direct filtration are discussed. The results show that the fractal dimension can be used for studying the deposition structure and its effect on the filtration process, and for estimating the effect of the coagulant in the direct filtration.更多还原
