Abstract:
A hydroclone (10) including a tank (12) with a fluid inlet (14), a filtered fluid outlet (16), an effluent outlet (18), a process fluid outlet (20) and a chamber (24) including an inner peripheral wall (22) centered about a central axis (X). The hydroclone further includes: i) a filter assembly (26) located within the chamber (24) which has an outer membrane surface (44) symmetrically located about the central axis (X) and encloses a filtrate chamber (46) that is in fluid communication with the filtered fluid outlet (16), and ii) a cleaning assembly (50) concentrically located and rotatably engaged about the membrane surface (44). A fluid pathway (28) extends from the fluid inlet (14) and defines a vortex region (25) between the inner peripheral wall (22) of the chamber (24) and the membrane surface (44) and is adapted for receiving incoming fluid. An inlet flow shield (58) is concentrically located about the filter assembly (26) and is adapted to block at least a portion of fluid flowing into the chamber (24) from the fluid inlet (14) from impacting the membrane surface (44).
Abstract:
Froth settling vessels (FSU) taught herein utilize a classifier feedwell to pre-classify a solvent diluted feedstream into a less dense bitumen and solvent overflow and a more dense water, solids and asphaltene agglomerate underflow. The overflow and underflow are discharged into the FSU at axially spaced apart locations, forming a substantially non-turbulent interface therebetween. The majority of the bitumen and solvent in the overflow rises to the top, following discharge above the interface, and the majority of the dense components fall to the bottom, following discharge below the interface. Minor amounts of less dense components in the underflow and more dense components in the overflow rise and fall substantially unimpeded through the interface. The FSU can be operated at flux rates exceeding conventional FSU as the risk of breakthrough is minimized as a result of the pre-classification and discharge to discrete locations within the FSU.

Abstract:
A method of purifying raw water comprises the steps of supplying the raw water to a generally vertical, open-ended inlet cylinder (23) in a reservoir (20), exposing the water in the inlet cylinder (23) to air for accomplishing oxidizing of matter, such as iron, manganese, and hydrogen sulphide in the water and/or agitation of the water, allowing the oxidized matter to fall down by gravity to the bottom of the reservoir (20), allowing the purified water to flow upwards past the inlet cylinder (23) and through a distribution disc (24) in the reservoir (20), and removing the purified water from the upper part of the reservoir (20).
