Abstract
This invention relates to filtering or straining of fluids where the suspended solids removed by filtration must eventually be discharged from the filter as a 'dry cake' discharge. The apparatus provides for the use of a central flow tube positioned within a filter element which is connected to a filter element drain pipe through a valve, which in case of multiple filter elements within a filtration vessel, controls draining of all elements. To assist in detecting a defective or malfunctioning filter element, a sample conduit with a sample valve is provided independently for each filter element.
