A mechanical separator for separating a fluid sample into first and second phases within a collection container is disclosed. The mechanical separator may have a separator body having a through-hole defined therein, with the through-hole adapted for allowing fluid to pass therethrough. The separator body includes a float, having a first density, and a ballast, having a second density greater than the first density. A portion of the float is connected to a portion of the ballast. Optionally, the float may include a first extended tab adjacent a first opening of the through-hole and a second extended tab adjacent the second opening of the through-hole. In certain configurations, the separator body also includes an extended tab band disposed about an outer surface of the float. The separator body may also include an engagement band circumferentially disposed about at least a portion of the separator body.

An inlet arrangement for a tray-based grit removal system utilizes a set of separate inlet hoses to connect the vertical stack of trays to a horizontally-disposed inlet chute, thus eliminating the inlet duct utilized in prior art configurations. Each hose is configured to have about the same length and diameter, providing an essentially uniform influent pressure at the input to each tray. The hoses are directly connected between the trays and the inlet chute, where each tray may be formed to include a hose coupler of the same diameter as the hose. The inlet chute may take the form of a trough or tube (or other suitable geometry), with the plurality of hoses all terminating along a common, horizontal output face of the chute.

A separation tank for crude oil. Fluid enters an inlet section of a center column of the tank via an offset inlet pipe so the fluid enters swirling. Solids that settle in the inlet section are removed by a center column drain and a solids removal system. Free gas rises and exits from the top of the tank. Liquid flows out of the center column via a diffuser that spirals the fluid evenly toward the wall of the tank where oil coalesces and wicks upward. Liquid flows downward around two flow diverting baffles where more oil coalesces and wicks upward via an oil conduit into the oil layer. The water flows under the lower flow diverting baffle and exits the tank through the outlet section. A large circular oil collector weir uniformly removes oil from the oil layer. Interface draw offs located below the oil-water interface remove excess BS&W.

A system for processing drilling mud, the system including a primary separation tank having an inlet for receiving drilling waste and an outlet in fluid communication with a feed line, and an injection pump in fluid communication with a polymer tank and the feed line. The system also includes a clarifying tank in fluid communication with the feed line and a first collection tank, wherein effluent from the clarifying tank is discharged into the first collection tank, and a centrifuge in fluid communication with the clarifying tank and a second collection tank, wherein effluent from the centrifuge is discharged into the second collection tank.

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. In particular, the described hydrodynamic separator is an improvement over other hydrodynamic separators known in the art with the inclusion of one or more down pipes which siphon water from the lower portion of the sump chamber. The inclusion of down pipes allows for an improved control of the velocity of the water flow through the device by distributing flow into more than one path.

A single stage clarifier mixing assembly includes a housing having a circular sidewall and a center axis, a mixing section in the housing, a clarifier section overlying and axially aligned with the mixing section along the center axis within the housing, an inlet delivering an inlet stream to the mixing section and an agitator. The agitator is adapted for mixing the inlet stream in the mixing chamber.

A method of separating a flow of multi-phase fluid includes directing the flow through the inlet opening of an enclosed tubular body comprising a tubular sidewall with opposed end walls, one or more axial outlet apertures formed through the end walls, and one or more radial outlet apertures formed through the tubular sidewall at locations spaced from the inlet opening. The method also includes directing the flow of multi-phase fluid onto one or more swirl plates positioned between the inlet opening and the outlet apertures, with the swirl plates having angled surfaces configured to impart a cyclonic motion to the flow so as to initiate separation of the constituents of the multi-phase. The method further includes directing the gas constituent axially outward through the axial outlet aperture and directing the oil constituent and the water constituent radially outward from the tubular body through the one or more radial outlet apertures.

A method for processing a 3D scene, and corresponding device, system and computer program are disclosed. In an example embodiment, the disclosed method includes: obtaining an image comprising at least a nadir view of a 3D scene, captured by at least one camera; detecting, in the image, at least one shadow cast by at least one object of the 3D scene acting as a support for the at least one camera; and determining a direction of at least one real light source from the at least one detected shadow and at least information representative of the object.
