Apparatus for treating water has a container having a clarification zone, a water entry arrangement for flowing water into the clarification zone, and water exit units mounted to the container for at least partial immersion in the water in the clarification zone. Each water exit unit has a transfer channel for transferring a flow of clarified water from a layer of the water to a predetermined depth in the clarification zone and to direct the received clarified water to a water exit arrangement. A height adjustment mechanism is used for differentially adjusting the heights of the water exit units and their transfer channels relative to the container so as to compensate for any angular tilt of the container owing to the container being deployed on sloping ground.

A passive filter cell having a basin with a floor and two or more vertical or upright sidewalls forming chute or container having first or left sidewall, second or right sidewall, and third or back sidewall, and fourth or front downwardly curved sidewall, an inlet positioned proximate a top of the fourth or front sidewall and an outlet positioned proximate the top of the third or back sidewall, wherein the floor is configured angled from the fourth or front sidewall to the third or back sidewall, discharge pipe positioned proximate junction between the floor and the third or back sidewall, and lip configured to extend from the top of the third or back sidewall into an interior of the basin.

A device and a method for installing an aerobic three-phase separator without interruption of production. The device comprises an aeration tank, the top of the aeration tank is provided with a number of aerobic three-phase separators that are capable of aeration at the bottom and are provided with a gas barrier at a sludge outlet. Each of the aerobic three-phase separators comprises an overflow trough, and the bottom of the overflow trough is provided with a drain pipe leading to the outside of the bottom end of the aerobic three-phase separator. Each of the drain pipes is connected to one end of a water outlet hose, and the other end of each water outlet hose is connected to a water outlet manifold. One end of the water outlet manifold is a sealed end, and the other end is bent downward and leads to a water level tank.

Removable trap stations for hydrocarbon flowlines can be implemented as an apparatus. The apparatus includes a multi-phase fluid receiver body and a tank defining an interior volume. The fluid receiver body is configured to couple to a flowline carrying a multi-phase fluid including solids and liquids. The fluid receiver body includes an inlet portion configured to receive a portion of the multi-phase fluid including a portion of the solids flowing through the flowline into the receiver body. The fluid receiver body includes an outlet portion fluidically coupled to the inlet portion. The portion of the multi-phase fluid is configured to flow from the inlet portion to the outlet portion. The tank is fluidically and detachably coupled to the outlet and is configured to receive and retain the portion of the multi-phase fluid received through the inlet portion

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 glycerin separation system heats a mixture of glycerin to about 231 degrees Fahrenheit and then allows the mixture to rest in a settling tank. Over time the mixture separates into layers of differing densities. The layers are removed individually by measuring the density of the exiting fluid. The glycerin is heating in a loop to allow for precise control of the temperature of the mixture. The pH is also controlled with a preferable level of 5.

The present invention discloses a centrifugal fuel purifying apparatus, including, a center shaft, a centrifugal cylinder, a shaft seat, a rotating skeleton, a disc type guide plate, a fuel gathering impeller, a rotating wheel, a vacuum pump, a fuel outlet pipe, a fuel inlet, pipe, a fuel unloading box, a pollutant receiving box, a tank body and a PLC controller, wherein the alarm fuel tank is arranged at the top in a tank body of the fuel tank, a fuel level meter is disposed within the alarm fuel tank, a fuel inlet is provided on the upper part of one side of the alarm fuel tank above the fuel level meter, a fuel outlet is provided on the lower part of one side of the alarm fuel tank below the fuel level meter, and the fuel inlet is communicated with the centrifugal cylinder through the fuel inlet pipe.

The invention relates to a waste water treatment plant comprising at least a multi-step water treatment reactor (1; 101) arranged for receiving influent waste water, for carrying out at least a biological step and a sedimentation step and for providing effluent pure water, by means of an effluent weir (4; 41, 42, 43), characterized in that there are providedmeans for increasing the sedimentation velocity (6), andmeans for hindering floating elements (10) to get into the effluent weir (8; 81, 82, 83).

A feedwell comprising a plurality of holes disposed in a bottom thereof, at least some of the holes having a tube disposed thereabout which extends downward or otherwise away from an interior of the feedwell. Optionally, a large center hole can be provided and it can have a tube disposed around it. By providing a plurality of holes spread across a large portion of the bottom of the feedwell, lower velocity flow rates from the feedwell to a sedimentation chamber can be provided, thus reducing induced turbulence in the fluid within the sedimentation chamber, while still providing sufficient separation of the feedwell from the sedimentation chamber so that the contents of the feedwell can be properly and adequately mixed.

An apparatus and method for trapping particles disposed in a fluid. The apparatus may comprise one or more cavities disposed axially along a length of a tubular housing, one or more connecting components disposed at opposing ends of the housing, and may optionally comprise a check valve system. Alternate embodiments are provided for forming each of the one or more cavities, which may comprise a combination of a cavity frame and cavity surface. The method may comprise flowing a fluid into a first end of a particle trap apparatus at a rate of fluid flow, directing the fluid flow at least partially through one or more cavity sub-assemblies disposed in the particle trap apparatus, collecting the particulate matter in one or more of the cavity sub-assemblies when the rate of fluid flow may slow or become suspended, and clearing collected particles from the one or more cavity sub-assemblies upon restoration of fluid flow in a primary direction of travel.
