Abstract:
1. A method for filtering water in an aquarium including the steps of: drawing water and waste material through a coarse screen into a pump; Increasing the velocity of the to-be-treated water and adding air to the stream; directing the high-velocity aerated stream into a macerating/comminuting chamber partially filled with objects, that are small enough to move freely throughout the chamber, and have a specific gravity high enough to develop inertia when moved by the stream; fluidizing the objects and water within the chamber; macerating organic material within the to-be-treated water with the objects impacting each other and the sidewalls of the chamber; constructing part of the chamber wall with a micro-screen, that also serves an outlet for treated water to exit said chamber; continuously cleaning the micro screen with the constant impacts of the fluidized objects; allowing only measured organic material to pass out of the chamber through the micro-screen, and into a porous media; treating the water with denitrifying microbes within the media; collecting and returning the treated water to the aquarium.
