Abstract
A panel filter for filtering waste media comprises at least two stacked filtering medium sheets. Each sheet is shaped to have two substantially identically-shaped portions integrally interconnected along an intermediate portion thereof. The stack of filtering medium sheets is folded over upon itself along the intermediate portions of the filtering medium sheets to create an inner central cavity of said stack and mating marginal edges that are secured and sealed together to form an outlet opening at a point along the marginal edges. A filtration conduit is received in the outlet opening of the panel filter and communicates with the inner central cavity of the panel filter.
