A method of treating flowback and produced water includes transferring flowback and produced water to a chemical treatment apparatus, mixing treatment chemicals with the flowback and produced water, transferring the mixture of treatment chemicals and flowback and produced water to a weir tank comprising a first end, a second end, an internal chamber, and a plurality of baffles positioned throughout the internal chamber to induce turbulent flow, transferring the mixture of treatment chemicals and flowback and produced water to a first settling tank that provides laminar flow, and transferring the mixture of treatment chemicals and flowback and produced water to a second settling tank that provides laminar flow.

A floating vessel with a filtration and testing device integral thereon, for simultaneously performing cleaning of fluid used in the oil and natural gas industry for completions, workovers, and commissioning of wells while simultaneously pressure testing of two separate groups of pressurized equipment using fluid cleaned by the filtration and testing device. The floating vessel having a hull with a support structure mounted thereto which contains a cleaning cycle assembly and a pressure testing cycle assembly connected in parallel to a controller for cleaning fluid and regulating pressure by comparing fluid pressures to preset limits. The controller regulates cleaning of first and second dirty hydraulic fluids and regulates pressure of cleaned hydraulic fluids and secondary fluids for pressure testing of the two different groups of pressurized equipment simultaneously.

Embodiments of the present disclosure include systems and methods for collecting, storing, separating, and disposing of waste material from an oil and gas well site in order to enhance payload efficiency. An embodiment of a method, for example, may include introducing a waste material into an enhanced-payload mobile vessel positioned at the oil and gas well site, the waste material selected to include one or more of a sludge waste material, a solids-laden wastewater material, and a dry waste material. The method may further include transporting the waste material when positioned in the enhanced-payload mobile vessel along roadways to an off-site waste management facility. Additionally, the method may include dumping the waste material from the enhanced-payload mobile vessel by a site-based lifting mechanism into a receiving vessel at the off-site waste management facility thereby to dispose of the waste material at a reduced transportation cost.

A transportable separation apparatus for separating spent materials from oil and gas operations into a primarily solid component and a primarily liquid component. The separation apparatus includes a first separation area disposed on the separation apparatus for receiving spent materials and beginning separation of the spent materials. The separation apparatus designed to be connected to a vehicle to be pulled on commercial roadways. The separation apparatus also includes a second separation area in fluid communication with the first separation area for further separation of the spent materials. The separation apparatus can further include an auger in fluid communication with the first separation area to remove the primarily solid component from the separation apparatus. A method of introducing and separating the spent materials via the separation apparatus.

A mobile flocculation and water treatment system includes at least one tank, preferably a series of adjoining tanks separated by weirs, and an adjacent pump house mounted on a mobile platform. At least one pump is mounted in the pump house. Fluid conduits run from the pumps to the tank. An overflow is mounted between the downstream tank and the pump house whereby fluid overflow from the tanks is directed into the pump house. The pump house provides a substantially water-tight reservoir zone to provide secondary containment. Water to be treated enters the upstream end of the tanks and is discharged from the downstream end.

A mobile water re-use system can include a chemical treatment apparatus, at least one weir tank in fluid communication with the chemical treatment apparatus, and two or more settling tanks in fluid communication with each other and at least one of the settling tanks in fluid communication with the weir tank. The weir tank can have a first end, a second end, an internal chamber, and a plurality of baffles that induce turbulent flow of fluid through the internal chamber. The settling tanks can provide, promote, facilitate, result in, and/or induce laminar flow of fluid through at least a portion of the internal chamber. Weir tanks, settling tanks, and method of treating flowback and produced water are also described.

Exemplary embodiments are directed to pool cleaners that remove debris from water using a plurality of cyclonic flows, or that include a removable impeller subassembly, a check valve for a debris canister, a particle separator assembly having a handle that locks to the pool cleaner, a modular roller drive gear box, or a roller latch that secures a roller to the pool cleaner. Exemplary embodiments are also directed to the check valve and the roller latch themselves. Exemplary embodiments are directed to a filter medium for pool cleaners that includes embossments providing flow channels for water, and to roller assemblies for pool cleaners. Exemplary embodiments are directed to pool cleaners including alternative pump motor engagements. Exemplary embodiments are directed to pool cleaners power supplies that include a potted and contoured power board assembly, and to kickstands therefor. Exemplary embodiments are directed to a pool cleaner caddy, and removable wheels therefor.
