摘要:
An overflow system for a hopper dredger comprises an overflow tube; an inlet for taking in head water from the hopper; and a collector to collect the flow of head water entering the inlet and guide the flow to the overflow tube. The collector comprises a substantially horizontal top portion which delineates a top of a flowpath for head water into the collector to ensure substantially radial flow into the collector. At least one of the overflow tube and the inlet is adjustable for controlling flow into the overflow system.

A system and method for processing a fluid, including decontaminating water and generating water vapor includes introducing the fluid into a vessel. The fluid is moved through a series of rotating trays alternately separated by stationary baffles so as to swirl and heat the fluid to effect the vaporization thereof to produce a vapor having at least some of the contaminants separated therefrom. The vapor is removed from the vessel for condensing apart from the separated contaminants and the remaining water. The vapor may be passed through a turbine connected to an electric generator. Sensors in a controller may be employed to adjust the speed of rotation of the trays or fluid input into the vessel in response to the sensed conditions. The treated fluid may be recirculated and reprocessed through the vessel to increase the purification thereof.

A blood separation chamber (18) is provided for rotation about an axis. In one implementation, the blood separation chamber (18) comprises a base (388) that includes formed walls that define a hub (120). A separation channel (126) extends about the hub (120). Flow passages (142, 144, 146) extend between the hub (120) and the separation channel (126). The hub (120) enables attachment of external tubing to convey blood to and from the separation channel (126) through the hub (120). In another implementation, the chamber (18) includes an interior channel, which includes a recess (386) that extends outside the bounds of the walls establishing separation zone. The recessed interior channel (386) permits the yields of individual blood components separated in the chamber to be maximized without cross-contamination or contamination by other components present in the chamber (18).

A tank for separating solids from a suspension of solids in a liquid, comprises an upper region containing a multiplicity of inclined plates 9 and a lower region for collecting solids settling from the upper region. The tank lower region has a sloping bottom 3 and the tank also includes an inlet 16 for introducing a suspension into the tank, a liquid outlet 19 and a plurality of solids outlets 22 at different fixed positions at the bottom of the tank for removing separated solids. Preferably the liquid entering the tank through the inlet is effluent treated to precipitate the solids as flocs which settle on the plates and then slide into the lower region of the tank. A suction pump may be connected to each of the solids outlets and used at intervals to remove solids collected in the vicinity of the solids outlet. Advantageously the tank is a mobile unit and includes lifting devices 20, 21 to enable the tank to be lifted by a fork-lift truck or a crane.
摘要:
Mobiles Wasserreinigungsgerät, bei dem ein Raum (2) für das zu reinigende Wasser (3) vorgesehen ist, sowie eine wenigstens einen Strömungskanal ausbildende Reinigungseinheit (7). Der wenigstens eine Strömungskanal ist geneigt zur Senkrechten angeordnet. Das zu reinigende Wasser (3) wird in dem wenigstens einen Strömungskanal von unten nach oben geführt. Hierbei setzen sich Schmutzpartikel des zu reinigenden Wassers nach unten ab, und das gereinigte Wasser tritt oben aus der Reinigungseinheit (7) aus.
摘要:
A microbial, sampling, filtration and recovery device (10) which utilizes a wash solution on meat carcasses and a vacuum source to vacuum the wash solution and suspended microbes into a collection device. The device (10) includes pre-filters (24 and 26) for removing debris, and a microbial filter (42). The size of the microbial filter (42) seriously reduces air flow, an alternate route for air is provided through a hydrophobic filter (36). Bacteria captured in the filter is backflushed into a collection vessel, where it is concentrated in a subsequent centrifuge step. The concentrated microbial sample is available for use in rapid detection methods.
