Abstract

A method of manufacturing a porous fluid treatment element, e.g. a filter element, includes forming a layered structure having at least two layers and subjecting the layered structure to at least a heat treatment. The step of forming a layered structure includes forming a first layer including particulate matter including at least a binder and applying a second layer including particulate matter including at least a binder directly onto the first layer on a first side thereof. The step of forming a layered structure further includes applying at least one of radiation and heat to at least the first side of the first layer prior to applying the second layer.
