Several factors influencing the depth filter coefficient λ are analyzed. Three models of the filtration coefficient, such as the surface area of the filter medium, the geometry of the flow path and the liquid flow velocity in the pore of the medium layer, are emphatically introduced. Under the constant pressure operation, the functional relationship between the filtration coefficient λ and specific accumulation σ was established, and the to-be-determined index in the formula was determined experimentally. Is to study the theory of deep filtration under constant pressure operation.
