Abstract: A new device, method, and system are disclosed that provide for removal of undesired materials from a contaminated fluid. Materials present in the fluids are kept in motion in one or more filter cassettes that include disc aerators that improve contact times with the sorbents and that rotate the filter media to pump contaminated water through the filter media for treatment of the contaminated fluids. The device and system provide containment of sorbent fines that keeps the filter media free from clogging.

Abstract: A fluid treatment device, system, and process are described that provide a filtered, metal-depleted (treated) fluid. The system includes two pairs of tanks that are piped and valved to allow one pair to fill/react while the other pair decants/discharges, which provides a continuous flow of metal-depleted (treated) fluid. Power requirements are minimal since fluid is pumped at a low head pressure. The design has applications in the potable water, industrial, mining, chemical and environmental sectors.

Abstract: A liquid management unit uses a substantially horizontal rotor device partially submerged in a liquid so that at least a portion of a rotating component or the rotor device moves a liquid above the surface of the body of water and is then collected in a container for filtering, irrigation, or other purposes. A flap may be used with the container for opening and closing the container to incoming liquid. A control device such as an endless screw, chain, or rod may be used for opening and closing the flap especially when it is located on the interior of a shroud. A flow restriction unit can also be used with the liquid management unit to provide increased velocity to incoming liquid. The flow restriction unit is formed as a U-shaped member with an open inlet and opposite open outlet end. The inlet end cross sectional area may be increased by angling the sides outward at the inlet or slanting the bottom downward from the outlet to the inlet ends.

Abstract: A liquid management unit uses a) a shaft mounted disc rotor partially submerged into a liquid for introducing flow-inducing energy and air or treatment gas into the liquid, b) a first baffle for receiving liquid from below the surface of a body of liquid and directing the liquid to the rotor, and c) a second baffle for receiving treated liquid from the rotor and directing the treated liquid below said surface of the body of liquid. The rotor and baffles may be mounted in various orientations including both horizontal and vertical positions. The disc rotor and first and second baffles are mounted on a frame that is supported by pontoons. A shroud placed over the disc rotor and input and output baffles with an air passage through them form a pressurized three-point aeration system in which the input baffle pre-aerates the water to satisfy chemical oxygen demand, the disc rotor transfers additional air to the water, and the output baffle post-aerates the water to satisfy the overall oxygen demand of the liquid.
