A method and apparatus for collection and disposal or utilization as a carbon neutral fuel of fats, oil and grease that includes a first porous container, a second porous container, and a grease trap having an inlet and an outlet. The first porous container is positioned proximate the grease trap inlet and the second porous container is positioned proximate the grease trap outlet. The first and second porous containers are formed of a porous fabric and contain an absorbent, organic hydrocarbon material capable of absorbing a quantity of fats, oil and grease. The second porous container may be positioned on either side of the grease trap outlet (within the grease trap or intermediate the outlet and an exit pipe) and may be held in a stationary manner via a tether and/or a hinged door having a flange for capturing and holding the porous container in a stationary manner.

A cyclonic inlet diverter for initiating the separation of a multi-phase inlet fluid flow comprises an enclosed tubular body mounted crosswise within a larger separator vessel. The inlet diverter includes a splitter plate positioned within a center portion of the tubular body and configured to split the inlet flow into a first stream and a second stream, and a swirl plate positioned on each side of the splitter plate with angled surfaces configured to increase the cyclonic motion of the first and second streams within the tubular body. The inlet diverter further includes elongate apertures formed through bottom sidewall portions of the tubular body on each side of the splitter plate, an axial aperture formed through opposing end caps of the tubular body, and at least one radial aperture formed through lateral sidewall portions of the tubular body proximate each opposing end cap.

There is an inlet baffle assembly for use in an in-line interceptor for separating FOG from wastewater and a method of cleaning the inlet baffle assembly without the need for removal from the interceptor. The inlet baffle assembly has an inlet baffle for the grease collecting chamber of an in-line interceptor which defines a flow channel through which influent enters the collecting chambers and has a moveable section moveable between open and closed positions. The inlet baffle assembly also has a flow control element to control the rate of flow of influent entering the flow channel when the moveable section is in the closed position. The flow control element is accessible for cleaning when the moveable section is in the open position. After cleaning, the moveable section is moved into the closed position to facilitate fluid flowing through the inlet baffle assembly into the grease collecting chamber.

An improved method for separating solids from liquid in a slurry comprising solids and a liquid (e.g., an aqueous solution) is disclosed. Combining the separator, the gun barrel and a weir tank together are plumbed there between for a simplified and easy system on wheels for the petrochemical industry. The disclosure allows for easy transportation and use thereof for smaller jobs and more frequent use.

A method, system, and apparatus directed to an innovative approach for the treatment of stormwater utilizing hydrodynamic separator assembly designed to maximize flow movement for more efficient sediment removal and maximize clearance space within assembly to facilitate cleaning and increase storage capacity of trash, debris, and sediment.

There is provided a method of treating fluid such as tailings from tailings ponds resulting from oil sands production. A fluid treatment separator has a separation chamber having an oil outlet and a water chamber having a water outlet below the height of the oil outlet. A fluid passage connects between the separation and water chambers. The fluid passage is below the height of the water outlet. A centrifuge flow separator is in the separation chamber. A centrifuge flow diffuser is oriented to direct mixed fluids into the centrifuge flow separator. Preferably, the centrifuge flow diffuser is a ring diffuser and the centrifuge flow separator is a centrifuge cone. A fluid treatment system includes a fluid treatment separator and a phase separator and may include multiple fluid treatment separators and phase separators connected in series.

An apparatus for refining a liquid stream using 180 degree redirection and inclined plates. The apparatus includes a first flow chamber, a second flow chamber, and a separation chamber. The first flow chamber directs the liquid stream downwards in a first direction at a first velocity, the second flow chamber directs the liquid carrier upwards in a second direction opposite the first direction, and the separation chamber is disposed between the first flow chamber and the second flow chamber. The separation chamber includes a redirection portion that has inclined plates across which the liquid carrier flows and, as the liquid slows from a first velocity to a second velocity, the solid particles fall out of the liquid carrier and collect in the collection portion of the separation chamber.

A separator for a gas stream has a horizontal tank with a fluid inlet, a fluid outlet and a flow path along the inside of the horizontal tank. A flow barrier is disposed within the tank between the inlet and the outlet. One or more sets of liquid ports are in fluid communication with the tank and positioned at a bottom surface of the tank. Each set of liquid outlets has a first port and a second port. The first port is positioned upstream along the flow path relative to the second port. A fluid passage is in fluid communication with the first port and the second port. The fluid passage defines a secondary flow path adjacent to the horizontal tank, where the first port acts as a draft inlet to the secondary flow path and the second port acts as a draft outlet from the secondary flow path to the tank.

An improved water-oil separation apparatus with a separation vessel and associated water leg having internal inlet piping that feeds fluids to an engineered degassing boot, having an engineered degassing boot that is more effective in removing entrained gases from the incoming fluid stream, having an umbrella shaped upper baffle instead of an inverted umbrella shaped upper baffle, having an improved oil collection bucket or weir, having a much improved inlet water spiral distribution apparatus, having an improved water leg design, and having a water leg with a functional height that is externally adjustable to make it easier to regulate the oil-water interface level within the separation vessel.

Coalescer plates, coalescer plate units, and coalescers, are provided. An exemplary embodiment provides a coalescer plate for separating a mixture of immiscible fluids. The coalescer plate comprises a pattern of wetting and non-wetting regions, wherein the pattern is based, at least in part, on phyllotaxis.
