1. A method for maintaining a suspension of materials in a tank, the method comprising:
connecting an inlet/outlet associated with the tank to a pump, wherein the tank contains a solid phase and a liquid phase; connecting an inlet of a plurality of inlets associated with the tank to the pump, the plurality of inlets independently operable by opening and closing a separate valve associated with each of the plurality of inlets; pumping at least the liquid phase from the inlet/outlet to the inlet, the pumping producing a circulation within the tank of at least the liquid phase; and connecting a high pressure gas source to the inlet/outlet; clearing a blockage of the inlet/outlet; and maintaining the solid phase in a suspension with the liquid phase, wherein the tank is configured to hold materials, the tank comprising a bottom and sides separate and distinct from the bottom; the inlet/outlet configured with the tank to allow a flow of the materials from the tank therethrough; the plurality of inlets configured to direct a flow of the materials along the bottom of the tank, each of the plurality of inlets oriented substantially toward the inlet/outlet; at least one conduit configured to direct the materials from the inlet/outlet to the plurality of inlets to agitate the materials in the tank to enhance removal of the materials from the tank; and the pump arranged to receive the materials from the inlet/outlet and transport the materials in the tank through the plurality of inlets, wherein the pump is configured to receive the materials from an outlet associated with the tank and transport the materials to the inlet/outlet through the at least one conduit. |
