Abstract:
A method for filtering a dirty liquid with a filter element to separate dirt components from the liquid, comprising the steps of:using a conveyor and a metering screw to deliver filtering aid to an inoculation container, wherein the filtering aid includes at least one of crushed corn and cellulose; mixing a clean liquid with the filtering aid in the inoculation container with a mixer; with an inoculation pump, adding the mixture of clean liquid and filtering aid to the dirty liquid that is to be filtered through a conduit through which the dirty liquid is delivered to a filtration plant; passing the dirty liquid containing filtering aid directly to a filter element surface to obtain a filtered liquid; and whereby a higher degree of purity of the filtered liquid and a longer service life of the liquid are achieved.
