Electrical power distribution control methods, electrical energy demand monitoring methods, and power management devices are described. In one aspect, an electrical power distribution control method includes providing electrical energy from an electrical power distribution system, applying the electrical energy to a load, providing a plurality of different values for a threshold at a plurality of moments in time and corresponding to an electrical characteristic of the electrical energy, and adjusting an amount of the electrical energy applied to the load responsive to an electrical characteristic of the electrical energy triggering one of the values of the threshold at the respective moment in time.

A solid-liquid separator that separates raw water containing suspended solids into suspended solids (solid) and treated water (liquid) in easy and a short time is provided. A solid-liquid separator includes a separation tub, an inflow pipe configured to rotate raw water which flowed from the outlet of the inflow pipe in the separation tub, a froth discharge pipe configured to discharge the suspended solids surfaced in the separation tub and a treated water discharge pipe configured to discharge treated water by which the suspended solids were removed from raw water from the separation tub.

A system for separating particles from a contaminated liquid stream includes an apparatus for mixing the liquid with one or more separation enhancement additives and gases. A pressure reducing device having a flow restrictor element within an enlarged tube receives the mixed liquid and creates bubble laden floccs by reducing the pressure of the liquid stream. The pressure reducing device empties into a bloom chamber of a flotation tank, where the bubble laden floccs are directed upwardly to an upper portion of the flotation tank. The flotation tank is configured such that the bubble laden floccs circulate within the upper portion of the flotation tank until they float to the upper surface, while decontaminated liquid flows to a lower portion of the tank for removal. A skimmer removes the floated contaminated floccs from the upper surface of the flotation tank into a dewatering apparatus.

A system and method for removing gas bubbles from blood during circulatory assist procedures. An active filter apparatus forces the bubbles to the center of the system where they are removed from the blood before the blood exits the filter.

A system and method is provided which includes using a liquid treatment apparatus, which is equipped with cyclonettes, for example, to subject a liquid medium processing stream in an alcohol production process to hydraulic cavitation, i.e., to shear under vacuum, at one or more locations. The liquid treatment apparatus, in one embodiment, is directed to the formation of a central axial jet and a vacuum chamber that can be sealed by the exiting jet. Cavitation is generated by directing a high velocity jet of liquid medium processing stream through a volume of vapor under a vacuum created in the chamber through which the jet travels. This can reduce the production cost of alcohol, such as ethanol, by improving alcohol yield per bushel, among other benefits. In one embodiment, the alcohol production process is a dry grind process, a modified dry grind process, or a wet mill process. In one embodiment the alcohol production process utilizes grain as a starting material.

A method for treating livestock wastewater includes directing screened wastewater to a hydrocyclone/separation tank system. The hydrocyclone directs the wastewater stream in a generally helical fashion to create bubble-particle aggregates. Activating chemicals can be added to the wastewater upstream of the hydrocyclone or within the hydrocyclone itself. The wastewater is channeled from an outlet of the hydrocyclone through a diffuser to a separation tank, where the bubble-particle aggregates are separated as they rise and accumulate on a free liquid surface of the tank. The treated wastewater settles below the bubble-particle aggregate accumulation and is transferred to a reservoir for later use as irrigation water or barn wash water. Salts may also be removed from the wastewater by filtering the wastewater through salt-removing filters before the wastewater is transferred to the reservoir.

A fluid conditioning system and method is disclosed for coupling to a first solution source comprising a suspension solution and particles suspended in the suspension solution. The fluid conditioning system includes a containment vessel defining a treatment environment and including a wall defining a fluid passage and a having an inlet apparatus. The inlet apparatus is coupled to the solution source for receiving a solution stream and directing the solution stream through the passage helically along the cylindrical wall. The containment vessel includes a sparging apparatus disposed downstream of the inlet apparatus for introducing a gas into the solution stream, and an outlet for discharging the sparged solution stream. The system further includes a flotation tank disposed proximate the containment vessel outlet for receiving the discharged solution stream. The flotation tank is adapted to carry a predetermined volume of a second solution to effect flotation of the particles to the surface of the second solution. The flotation tank further includes a tank outlet for exiting processed effluent from the tank.

Fluid conditioning system and method

A gas is dissolved into a liquid by first pressurizing the liquid to a predetermined level. The pressurized liquid is then directed into a hydrocyclone to form a vortex stream having an evacuated central area. The hydrocyclone has an inlet aperture size and configuration and a barrel diameter and length optimized for liquid particle movement through the liquid vortex stream. Gas is injected into the evacuated area for absorption into the liquid vortex stream. The liquid is then directed from the hydrocyclone into a diffusion column, and subsequently to a pressure chamber in order to collect non-adsorbed gas. The collected non-adsorbed gas is then recycled back into the evacuated area of the vortex stream. Pressurized gas is added to the system as the gas is adsorbed and dissolved into the liquid.
