Abstract
Water filtration systems are disclosed. The water filtration systems include a regenerative media filter vessel comprising a housing, an inlet, and an outlet, a diffuser fluidly connected to the inlet and disposed within the regenerative media filter vessel, and at least one pump configured to direct water through the water filtration system. The housing of the regenerative media filter vessel comprises a concave lower portion centered about a vertical axis of the vessel. The position of the diffuser along a height of the regenerative media filter vessel is determined by at least a ratio of the height to an inner diameter of the regenerative media filter vessel and a radius of curvature of the concave lower portion. A regenerative media filter including a diffuser having asymmetrically spaced apertures is also disclosed.
