Abstract
The invention is a filter apparatus and method for separating suspended solids from fluids, particularly liquids. A filter chamber is defined inside a filter housing. Inside the chamber is a filter bundle, consisting of two or more filter screens, of a non-woven construction. Spaces between the filter screen strands provide channels for fluid to flow through the filter bundle along a tortuous path that is parallel to each screen. These spaces also define openings for directing a flushing fluid, such as air, in a crosswise direction through the filter screens. The crossflow path of the flushing fluid removes solid particles trapped in the channels of the filter screens.
