Provided is an apparatus and method for performing tertiary treatment of sewage based on porous filtering media. The apparatus for performing tertiary treatment of sewage based on porous filtering media includes a reaction tank for receiving effluent wastewater from a primary settling tank; and porous filtering media, which is located in the reaction tank and has a predetermined size of surface area and opening, for settling suspension in the effluent wastewater and removing organic matter and nutritive salts included in the suspension.

A single solvent method and machine for separating bitumen from oil sand ore are disclosed. The method includes the use of a single light paraffinic solvent, such as propane or butane as the agent to separate the bitumen from mined oil sand ore. Since light paraffinic solvents are vapors at atmospheric pressure and temperatures, the ore is placed in a pressurized container so that the solvent remains in a liquid state. When the container is pressurized, by the addition of the solvent itself, the liquid solvent is mixed with the ore to effect separation. The proposed machine settles more than 80% of the solids out under gravity in a modest period of time. The solvent-bitumen mixture is drained after the cleaning cycle, the container is depressured to a vapor recovery system and the remaining solids dumped out. The fine solids, drained with the liquids, are separated from the liquid mixture with relative ease by the use of current technology in other downstream equipment.

An apparatus for dewatering dredge spoils includes a floating barge having a planar upper surface or deck. One end of the barge, such as the stern, is partially flooded or otherwise ballasted so that the deck slopes downwardly from the bow toward the stem. Dredge spoils removed from a waterway are deposited onto the bow where they flow down toward the stem. A plurality of concrete blocks on the deck form an attenuator that, in turn, defines one or more settling ponds on the surface of the barge. A weir across the stem of the barge forms an additional settling pond at the rear of the barge. Solids suspended in the water removed from the waterway settle out onto the deck when the dredge spoils are deposited onto the bow. Remaining solids suspended in the water deposit onto the deck as the water flows through the settling ponds. The relatively clear water that remains then flows back into the waterway off the stem of the sloped barge after passing through the settling ponds. Because the apparatus and method use materials and equipment, such as the barge and blocks, that are already likely to be on hand, the method and apparatus are particularly economical and easy to implement.

A memory module testing apparatus and method include a test slot adapted to receive a target memory module, wherein the target memory module includes a first memory unit to store information related to the target memory module. The memory module testing apparatus further includes a second memory unit adapted to store information related to a memory module, and a first switching unit adapted to selectively provide a driving signal to at least one of the first memory unit and the second memory unit.

A chip discharge device of a machine tool includes a coolant tank storing coolant which is supplied to and dropped from a machining point, and a chip conveyor discharging chips which are generated at and dropped from the machining point, to an outside of the machine tool. A bottom wall of the coolant tank is inclined in a chip discharge side by mounting the coolant tank to the bed.
