A scum removal system for use with a wastewater treatment clarification tank containing wastewater is provided and includes a debris intake conduit, a debris discharge conduit, and a pump article. The pump article is configured to be in flow communication with the debris intake conduit and the debris discharge conduit, wherein the pump article and debris intake conduit are configured to generate a suction within the debris intake conduit and wherein the debris intake conduit is configured to be located proximate the wastewater. Additionally, the debris intake conduit is sloped downwardly at a debris intake conduit angle β, and the second discharge conduit is sloped downwardly at a debris discharge conduit angle Ω.

A tank system may be conventional and fixed, or mobile, such as a fracking fluid or other tank trailer. A drain port thereof is fitted with an adapter connecting a snorkel system to drain liquids from near the top of the liquid level in the tank. A snorkel head at the extreme distal end of a tube near the longitudinal center of the tank is suspended by a system of buoys. A flow field controller resists formation of vortices near the snorkel head, so it can operate as near the surface as possible, withdrawing the highest grade oil efficiently without entrainment of overlying gases and vapors, nor the second liquid layered therebelow. All are configured to fit into the tank without requiring any personnel to enter the tank. Oil, water, and sludge may drain through the system to exit the tank.

This disclosure relates to shaker adjustments based on sensor measurements for sensors positioned at different locations about the shaker. This disclosure explains techniques to adjust a shale shaker as would be used to separate particulates (cuttings and other solids) from drilling fluid (commonly referred to as mud) during a drilling operation. Empirical models have been formulated to provide for programming a controller to calculate run-time adjustments to the shaker to increase efficiency. The controller may control one or more shakers concurrently. Different techniques and measurement types may be used concurrently to achieve desired shaker inclination and maintain a proper beach location during operation. Sensors include accelerometers, proximity sensors, and other types of data acquisition devices that may be used to detect motion parameters of an operational (e.g., in-use and running) shaker.

A system and method for processing interface emulsion, water, and solids contained within a separator vessel that comprises the steps of continually extracting those components from the vessel and then passing them through a gas flotation cell. The cell, which is preferably a vertical induced gas flotation cell, separates the oil and water contained in the interface emulsion and discharges recovered oil from an upper portion of the cell and treated water from a bottom portion of the cell. The recovered oil and treated water may be further processed and recycled to the vessel or sent elsewhere. The treated water may also be recycled to the cell or sent to a process sewer. Fuel gas residing in an upper portion of the cell may be cooled and passed through a splitter. All the steps of occur in a closed system with no air emissions.

In some embodiments, a pre-treatment source generates pre-treated oilfield fluid from oilfield fluid, prior to injection into an inverting filter centrifuge system. The pre-treatment source increases an efficiency of separating solids from the injected oilfield fluid. An inverting filter centrifuge coupled to the pre-treatment source generates filtered oilfield fluid from the pre-treated oilfield fluid. Post-treatment may be applied to the filtered oilfield fluid. Additional apparatus, systems, and methods are disclosed.

A diffuser and solids collection system includes an enclosure including an input for receiving from a petroleum well a stream of fluid carrying solids. A set of baffles within the enclosure reduces the velocity of the stream of fluid. A solids collector in fluid communication with the enclosure receives the stream of fluid after the reduction in the velocity of the fluid by the set of baffles. A weighing system coupled to the solids collector for weighing the collected solids.
