摘要： A screw-type fluid pump is provided with an elongate casing having a surface defining an internal fluid flow space and a screw within the flow path, fixed to the casing, and having a plurality of flights for continuously conveying fluid from an inlet on the casing to an outlet for appropriate disposition as the screw and casing are rotated. A conduit/torque tube extends through the screw in axially overlapping relationship with the casing over no more than one third the axial extent of the screw at the upper region of the casing. The conduit/torque tube establishes communication between a plurality of pockets between screw turns and the atmosphere to effect pressure equalization so that cavitation in the fluid flow space is prevented as the screw is operated. The conduit/torque tube also transmits the force from a rotary drive to the screw.

摘要： A filter compartment containing water with surface scum is bounded by first and second end walls and spaced side walls, the latter of which are spanned by a moving bridge. The bridge is movable between the ends of the compartment and has associated nozzles which direct a pressurized air or other fluid angularly against the upper surface of the scum layer to skim the scum towards at least one collecting pot, in which scum is collected, and from which the scum is withdrawn for delivery to a scum pit for further treatment or disposal.

摘要： Waste water treatment apparatus including a vessel for receiving the waste water and having an inlet and an effluent outlet spaced from the inlet. The space between the two defines a flow path for the waste water and a scum outlet is also provided for the vessel. An elongated trough having an elongated opening is disposed horizontally in the vessel at an intended level of waste water therein and extends across the flow path. A movable skimmer blade extending below the intended level of waste water can be drawn along the flow path to capture scum and deliver and deposit the same in the trough through the opening thereof.
