Bead fluid treatment self-cleaning apparatus and method

A device for treating a fluid comprising:

• (a) a chamber body with an inlet and outlet portion including a vertical flow path and a sideway flow path that intersects the vertical path, wherein a lower end of the vertical path forms a fluid inlet opening and an upper end of the vertical path is open, wherein the sideway path includes an inner end connecting with the vertical path and an outer end that forms a fluid outlet opening, an inlet screen that extends across the vertical path at an elevation that is below the sideway flow path, and an outlet screen extending across the sideway path at a location that is outside of said vertical flow path;
• (b) the chamber body also with an agitation area defining a vertical flow path having upper and lower ends that are open, wherein the lower end of the vertical path of the chamber body agitation area is connected to the open upper end of the vertical path of said inlet and outlet body portion;
• (c) the chamber body also with a closure attachment defining a vertical flow path having upper and lower ends that are open, wherein the lower open end of the vertical flow path of the closure attachment is connected to the open upper end of the vertical flow path of the chamber body agitation area portion;
• (d) a closure for closing the open upper end of the vertical flow path of the closure attachment;
• (e) a plurality of reactive beads disposed in the chamber body defined by a portion of the vertical flow path of the inlet and outlet body portion disposed above the inlet screen, the vertical flow path of the agitation area of the chamber body, the vertical flow path of the closure attachment, and the closure;
• and
• (f) whereby a flow of fluid directed into the inlet opening will cause the reactive beads to move upwardly from the inlet screen toward the agitation area of the chamber and fluid exiting the outlet opening will cause the reactive beads to move downwardly from the agitation area of the chamber toward the inlet and outlet portion, the chamber thereby agitating the reactive beads within the chamber.
