    摘要: Shipboard wastewater undergoes treatment within an automatic system based on membrane bioreactor technology. Bacteria that are naturally present in the raw waste stream break down during treatment and consume organic material in the wastewater. Membranes in a bioreactor within which the wastewater is treated provide a physical barrier, retaining the bacteria and other solids while producing an effluent sufficiently clean to be discharged directly overboard. To ensure adequate treatment, a flow-through ultraviolet disinfection unit is employed in the system downstream of filtration. Inorganic and other non-biodegradable material that accumulates in the bioreactor with time is removed automatically to maintain the desired solids concentration in the bioreactor. Using selective control established through the operator interface, the system can be operated under automatic process/standby mode or maintenance mode, and sludge concentrate can be directed either overboard, to an onboard storage tank or to undergo further treatment within a concentration device or destruction within an incinerator for example, depending on the ship's equipment, location and operating conditions.

    摘要: A door and doorway construction includes a doorway structure having a lock jamb, a hinge jamb, and a header defining a doorway opening. An adjustable door is constructed to fit mateably into the doorway opening. The doorway structure includes an overhead expressway construction configured to structurally support a weight of the door and further adapted to carry utilities over the doorway opening. The doorway structure is vertically adjustable to align the expressway construction with adjacent wall units, which results in size changes in the doorway opening, and the door is adjustable to define an adjustable vertical height shaped to fill the doorway opening despite the size changes. In one form the door is pivoted to the doorway structure with hinges located above and below the door and at a centerline of the door. In another form, the door is slidably mounted to the doorway structure by a door-supporting boom that includes a trolley rollingly supported by the doorway structure and a downrigger that is rigidly supported on the trolley. The downrigger pivotally supports the door, and the trolley includes a breakaway latch such that the door can be broken away and pivoted outwardly if the door is pressed on with sufficient force. Additional illustrated door embodiments include a solid wood door and a floor-to-ceiling door that incorporate the above features.
