  • Patent number: 8968580
    Abstract: A pumpbox apparatus includes a reservoir volume having a first inlet for receiving a feedstock stream and a second inlet for receiving a water stream, the reservoir volume being in communication with a discharge outlet disposed to discharge accumulated liquid from the reservoir volume. The reservoir volume is operable to accumulate the feedstock stream and the water stream in the reservoir volume while withdrawing a discharge stream through the discharge outlet to cause a flow of liquid through the pumpbox. The first inlet defines a first flow velocity region between the first inlet and the second inlet and a second flow velocity region between the second inlet and the discharge outlet. The first flow velocity is lower than the second flow velocity to facilitate flotation of a low specific gravity portion of the feedstock through the first region toward an upper surface of the liquid accumulated in the reservoir volume.

  • Publication number: 20120325754
    Abstract: A method and apparatus is provided for water filtration of a milk of lime solution that contains water, impurities, and grit particles, in which the milk of lime solution enters a vessel, and wherein turbulence is created in the vessel, by which larger grit particles settle out of the milk of lime solution, to form a bed of grit particles in the lower end of the vessel, such that grit particles and impurities are filtered from the lime-treated water that comprises a milk of lime solution, with water then being drawn off, that may be discharged out one or more dosing locations and/or recycled back for further filtration, as may be desired.

  • Patent number: 8287729
    Abstract: A lightweight water treatment system which can be easily distributed and employed by disaster survivors for treating locally available freshwater sources. The water treatment system includes an internal storage volume for maintaining a predetermined volume of water, a water fill port in communication with the internal storage volume provided at a first end of the elongated container for receiving the predetermined volume of water, a sealing member disposed at about the first end of the elongated container for maintaining the volume of water within the internal storage volume, a second end of the elongated container for receiving sediment settling out of the predetermined volume of water and a discharge port disposed superjacent to the second conically-shaped end for controllably releasing at least a portion of the water maintained within the internal storage volume of the elongated container.

  • Patent number: 8273248
    Abstract: A method for separating neutral lipids from plant material, in particular, intact algal cells, using an amphipathic solvent set and a hydrophobic solvent set. Some embodiments include dewatering intact algal cells and then extracting neutral lipids from the algal cells. The methods provide for single and multistep extraction processes which allow for efficient separation of algal neutral lipids from a wet algal biomass while avoiding emulsification of extraction mixtures. The neutral lipids are removed after first removing a polar lipid fraction and a protein fraction. These neutral lipids can be used to generate renewable fuels as well as food products and supplements.

  • Patent number: 8262912
    Abstract: Bioactive compounds extracted from a fermentation broth created by a unique microbial community during a fermentation process and fractionated into several fractions based on size. Four of the resulting fractions stimulate growth of plants that are planted in soil to which the fractions have been applied. The fractions can be applied to the soil individually or combined together prior to application. In another embodiment, the unique fractions can be freeze dried or spray dried.

  • Patent number: 8221634
    Abstract: A process and an apparatus for separating and recovering waste alkali from a cyclohexane oxidation solution are provided. A gradient combination of the gravity separation technique, the vortex separation technique and the coalescence separation technique is used to carry out fine separation of the waste alkali liquor from the cyclohexane oxidation solution. The purified cyclohexane oxidation solution is fed into a down-stream apparatus. Most of the waste alkali liquor thus separated is recycled, while the remaining is expelled. The expelled waste alkali liquor is incinerated in an incinerator, followed by recovering the molten species using a pneumatic pulverization process.
