  • Method of and apparatus for controlling the quantity of filter aid fed to a sediment filter so as to maintain virtually constant a preselected optimum specific cake resistance
    Patent number: 4514306
    Abstract: A system wherein suspended solids are separated from liquids by passage through a filter after a precoat of filter aid has been deposited on a filter septum. The subsequent addition of filter aid to the liquid and its deposit on the precoat are so regulated that the filter cake produced maintains a practical specific cake resistance to flow therethrough at a preselected value, even if the concentration of suspended solids varies with time, said value being the ratio .DELTA.R/.DELTA.W, where .DELTA.W is a small increment of filter aid weight fed and .DELTA.R is an incremental increase in cake resistance to flow corresponding to that increment .DELTA.W, both increments being on a per unit of filtration area, and the resistance to flow being the differential pressure across the filter cake divided by the flow rate per unit of filtration area.
