A grease recovery device 1 having a container 2 with walls 3 and a lid. The grease recovery device 1 further having a drum 5 for lifting fats, oils, grease and/or solids (FOGS) rotatably mounted on the container 2 and a wiper blade assembly 6. The wiper blade assembly 6 being in operable engagement with the drum 5. A wall 3 of the container 2 has an arrangement 7 for releasably housing the wiper blade assembly 6 in an operational position in the container 2. The releasable housing arrangement 7 comprising an opening 8 for slidably receiving the wiper blade assembly 6 and a support arrangement 9 disposed at or about the opening 8 so as to allow the wiper blade assembly 6 to be inserted into and removed from the grease recovery device 1 without removing the lid or opening any cover of the container 2.

A skimmer apparatus is provided to separate a less dense upper liquid layer from on top of a denser lower liquid layer. The skimmer apparatus includes a skimmer vessel at least partially submerged within a fluid and preferentially receive the less dense fluid. A first conduit is located within the skimmer vessel by a plurality of support arms. The plurality of support arms affixes the first conduit's vertical and radial location within skimmer vessel. In use, the skimmer height is set to collect the less dense fluid into the skimmer vessel. A lower end of the first conduit is in fluid communication with the inside of the skimmer vessel and the collected fluid therein. An upper end of the first conduit is configured for being suctioned thereby withdrawing fluid from the skimmer vessel.

A process of dewatering oil sands/coal tailings includes generating nanobubble water, mixing a chemical dispersant into the nanobubble water to form a nanobubble-dispersant mixture, adding tailings to the nanobubble-dispersant mixture to form a nanobubble-dispersant-tailings mixture, and agitating the nanobubble-dispersant-tailings mixture to form an agitated nanobubble-dispersant-tailings mixture having a solid portion and a liquid portion. The solid portion is thereafter separated from the liquid portion. The agitation may be a centrifugal motion or shaking motion to agitate the nanobubble-dispersant-tailings mixture The chemical dispersant may be sodium hydroxide dispersant for asphaltenes and the volume of the tailings added may be substantially equal to the volume of the nanobubble water generated. An oil layer may further be skimmed off the liquid portion a polymer clarifier may also be added to the liquid portion. The process may be applied to achieve accelerated tailings processing for rapid and economic environmental remediation.

A swirl-type demulsification and dehydration device for oil-water emulsions, including a swirler. An open end of a swirl chamber of the swirler faces towards an underflow pipe and communicates with the underflow pipe through a composite curved pipe section coaxial with the swirl chamber. A large-diameter end of a concave arc transition section is connected to the open end of the swirl chamber, is the same with the swirl chamber in inner diameter. A large-diameter end of a straight cone transition section is tangent to a small-diameter end of the concave arc transition section. A small-diameter end of the straight cone transition section is tangent to a large-diameter end of a convex elliptical arc transition section. A small-diameter end of the convex elliptical arc transition section is connected to the underflow pipe.

Provided is a toothed drum type oil recovery device, which includes: a recovery drum having a center coupled to a rotary shaft and having a plurality of tooth units formed around an outer circumference thereof, wherein one side of the recovery drum is disposed in the water to which oil is spilled so that the oil is recovered by the tooth unit at one side of the recovery drum according to the rotation; and a separation unit containing an oil separating liquid and disposed at the other side of the recovery drum, wherein when the tooth unit moves onto the oil separating liquid at the other side of the recovery drum according to the rotation of the recovery drum, the oil separating liquid is introduced into a space between the tooth units adjacent to each other by means of a capillary action to separate the oil from the tooth unit.

A solvent removing apparatus includes a container containing an emulsion comprising a first raw material of a continuous phase and a second raw material of a dispersed phase, an impeller rotating in the container to stir the emulsion, and a foam breaker spaced apart from the impeller on an upper portion of the impeller, positioned below a surface of the emulsion to be submerged in the emulsion when the emulsion is calm, and rotating to reduce foam generated during stirring of the emulsion.

A hydrocarbon removal apparatus includes a plurality of fibers and a backing substrate. Each of the plurality of fibers includes a proximal end and a distal end. Each proximal end is secured to the backing substrate.

Separation of particles or droplets from a host fluid may be achieved using a transducer and/or reflector that is a thin, non-planar structure. The thin non-planar structure improves operation of an acoustic standing wave generated by an acoustic transducer. The structure may operate as a pressure release boundary and may be constructed as plastic film.

A distillation system and method. The system includes a recirculation pump and a separation system for receiving a multi-media fluidic solution and operating at a temperature different than ambient temperature and at a pressure different than ambient pressure. The system further includes a separator for separating heavier particles from the multi-media fluidic solution. The separator separates heavier particles from the multi-media fluidic solution at the temperature and pressure of the separation system.
