  • Patent number: 9879211
    Abstract: A large-type horizontal device and a method for continuous methane fermentation. The whole distribution of a fermentation compartment uses a U-shape plane layout, which is a snap-back type and uses a material propeller. The material propeller has two axes and two blades and is constantly occluded with counter rotation. The irreversible propulsion of materials can be realized through counter rotation of two occluded blades. The propeller is set at the bottom of the main partition of the fermentation compartment. The propel ability of propeller can be changed through changing of rotation speed. Counter rotation of two occluded blades can realize material propeller without material reverting. The inlet and outlet entrances of the reactor in the disclosure are near to the ground and can be operated conveniently. The homogeneous output of materials and entire plug-flow can be realized at the same time without material mixing in the whole process.

  • Patent number: 7695675
    Abstract: A method of inactivating microorganisms such as viruses within a fluid such as a biological fluid is disclosed. The method includes the steps of providing a UV reactor, which may take the form of an elongated generally annular reaction chamber surrounding at least one elongated UV lamp, moving the fluid within the reaction chamber in a primary flow directed along the length of the UV lamp, and inducing a circulating secondary flow within the fluid with the secondary flow being superimposed on the primary flow. As the fluid moves through the reaction chamber in the primary flow, it is circulated repeatedly toward and away from the UV lamp in the circulating secondary flow to provide uniform and controllable exposure of the entire volume of fluid to ultraviolet radiation. Microorganisms such as viruses are thus inactivated while desirable components in the fluid, such as proteins, are preserved without the use of a free radical scavenger.

  • Patent number: 7509759
    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. 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.

  • Patent number: 6849176
    Abstract: An oil/grease separator separates a lighter liquid from a mixture of the heavier liquid and a lighter liquid. A housing has an inner volume, an inlet to receive influent flow, an outlet to discharge the heavier liquid, which defines a static liquid level, and an outlet port above the static liquid level to discharge substantially all of the lighter liquid and portions of the heavier liquid. The lighter liquid floats on the heavier liquid, so that large volume flows into the inlet raises the liquid level in the housing, flowing the floating lighter liquid through the outlet port.

  • Patent number: 6761822
    Abstract: A filter for filtering a fluid, such as lubricating oil for an engine, has a first element for trapping small particles and a second filter element for trapping sludge, the second filter element being stacked on the first filter element. A flow-deflecting element is disposed between the first filter element and second filter element to provide a spinning motion to oil flowing from the second filter element as that oil joins oil which is passed through the first filter element. The spinning motion of the oil from the bypass filter element encourages mixing of the oil from the second filter element with the oil filtered by the first element. A centrifugal separator is disposed in an annular space between the filter elements and filter housing for imparting a rotary motion to the fluid prior to the fluid passing through the filter elements. This removes large particles from the fluid by centrifugal force so that large particles do not add to the contaminant load in the filter elements.

  • Patent number: 6592754
    Abstract: An apparatus for separating solid particles from the suction effluent of, for example, a dental office, preferably driven by a dental office vacuum pump, includes a surge tank for accommodating effluent overfill connected to a sedimentary deposit tank for sedimentation of effluent particles. A bypass conduit is connected to the surge tank inlet which is equipped with a vacuum break valve for allowing air into the system when the suction openings are closed. The sedimentary deposit tank has a series of baffle chambers through which effluent flows in sequence, and in each of which chambers sediment is deposited for later removal. The surge tank preferably has a liquid level sensor and warning device. Modular filters or adsorbants may be installed in the sedimentary deposit tank, or a modular auxiliary filter may be connected downstream of the tank. Chemical injection may be used to improve sedimentation.

  • Patent number: 6517719
    Abstract: A storage tank includes an oil and water separator in which the frontal area of the coalescers is increased relative to known arrangements of coalescers in oil and water separators. By arranging the coalescers such that the surface area of the coalescers is increased, the efficiency of the coalescers is increased. In some preferred embodiments, the coalescers are arranged in a bank with free flow fluid paths between the coalescers in the bank, each of the paths being closed by a baffle on one end and open on an opposite end, and the baffles are arranged such that the open and closed ends of paths alternate. In other preferred embodiments, the coalescers are arranged in a tubular fashion and fluid flows from the outside surface of the tube through the coalescers and out a central path.

  • Patent number: 6383383
    Abstract: A combination cyclonic separator, multi-stage filter and pump is disposed within a cylindrical housing disposed around a vertical axis. A fluid inlet in a bottom portion of the housing causes the water to circulate with greater flow on the outside of the housing than on the inside thereof, thereby causing debris suspended within the water to accumulate closer to the inside and bottom than to the outside and top of this portion of the housing. A plurality of plates causing the flow to go between a first plate and the inner wall of the housing and through an opening in the inside of the second plate serves as part of a second stage of filtering large particles. A third plate disposed above the second plate forces water again between the periphery of the second plate and the inner wall of the housing to complete a preferred embodiment of the second stage filtration. A filter media is interposed in the housing after the second stage and catches the finer particles suspended in the water.

  • Patent number: 6350379
    Abstract: A filter for filtering a fluid, such as lubricating oil for an engine, has a full flow filter element and a bypass filter element stacked on the full flow filter element. A flow-deflecting element is disposed between the full flow filter element and bypass filter element to provide a spinning motion to oil flowing from the bypass element as that oil joins oil which is passed through the full flow filter element. The spinning motion of the oil from the bypass filter element encourages mixing of the oil from the bypass filter element with the oil filtered by the full filter element. During operation of the engine this arrangement tends to provide cleaner lubricating oil and therefore reduces engine wear while increasing the time interval between scheduled maintenance.
