Deep-bed filtration: Accumulation-detachment model parameters

摘要: Abstract Bed capacity, expressed in weight of accumulated material per unit bed volume, and hydraulic conductivity, velocity terms, are suggested to effectively represent retention ability the clogging process deep-bed filtration. A mathematical relationship between these parameters specific deposit was established on basis saturated flow soil equations, some filtration models experimental results. The controversial issue detachment breakup adsorbing particles within filter pores is discussed this work light parallel phenomena flocculation. It concluded that a proper description behaviour should take into account mechanisms which oppose removal.
