摘要： The method of forming a filter cake from a slurry comprising the steps of feeding the slurry into a filter housing, wherein the filter housing includes a plurality of vertical filter elements; pressing the slurry into the filter housing against the filter elements resulting in i) a filtrate passing through the filter elements and exiting out an exhaust port of the filter housing; ii) forming a solid cake on the filter elements; feeding a wash liquid into the filter housing while draining out the slurry by opening the slurry drain valve; closing the slurry drain valve and then continually feeding wash liquid through the cake and into the filter tube of the filter housing; stopping the feed of wash liquid; introducing a gas into the filter housing and draining out the wash liquid by opening a bottom drain valve; stopping the gas flow and opening a drain to exit most of the gas and remaining wash liquid; opening the bottom cake discharge valve; and back pulsing by a gas to break and to release the filter cake from the filter elements of the filter housing.
