Abstract: 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.

This invention takes advantage of the properties of the functional groups of a surfactant, by using the surfactant to allow a hydrophobic medium to attract water, attach the water molecules to the hydrophobic medium, and then allow for agglomeration of the water molecules, which finally become large enough to detach and be swept away by the sweeping-flow. This invention can thus be used to remove high concentrations of water, up to 5%, in hydrocarbons, while allowing a high flow rate by preventing blockage of the final filter by water.

A solenoid valve operates to allows air from a compressor to flow into the top of the tank through a shuttle valve which is opened by the air pressure. Simultaneously a drain valve connected to the shuttle valve opens a drain, venting water and air from the tank. The shuttle valve, closed by the solenoid valve, closes the air supply line and connecting the shuttle valve to atmosphere, and pressure within the aeration tank can close the shuttle valve, which causes closing of the drain valve. The part of the valve which opens the drain is made responsive to excess pressure within the air tank to open the drain and so acts as a pressure relief valve.

Abstract: An apparatus for concentrating and stabilizing conjugated estrogens from pregnant mare urine on solid adsorbent supports to obtain a starting material for pharmaceuticals that contain a natural mixture of conjugated estrogens as active ingredient. The apparatus is suitable for decentralized concentration and stabilization of conjugated estrogen mixtures on cartridges in the vicinity of the horses.

Only the loaded cartridge is transported, and transport can occur at longer intervals of up to several weeks. The stability of the conjugated estrogens on the adsorber assures there is no risk of decomposition.

Abstract: The inventions separate the activated sludge, biochemical reaction stages of the batch treatment process of a sequencing batch reactor from the clarification and sedimentation stages by separating the locations where each process takes place. The separation may be accomplished in a variety of ways including constructing separate basins for each process, installing baffles or other partitions in a single vessel to isolate the areas where each process takes place, or other methods of process separation as are known in the art.

In a conventional SBR process, the cycle of operations for clarification and sedimentation are dependent on a preceding biochemical reaction step. However, in the present invention the clarification and sedimentation operations are independent of the biochemical reaction operations.
