Systems and methods for removing iron from waste water employ one or more oxidizers, one or more treatment tanks having one or more self-generating and self-sustaining active sludge layers, and one or more spray-atomizing devices. A mixture of flowback fracturing water, or produced water, and the one or more oxidizers is spray-atomized by the spray-atomizing device inside the one or more treatment tanks. The atomized mixture settles in the one or more treatment tanks resulting in one or more self-generating and self-sustaining active sludge layers and one or more treated solutions. Additional mixtures of the flowback fracturing water, or produced water, and the one or more oxidizers may be continually spray-atomized into the one or more treatment tanks and filtered by the one or more sludge layer(s) so as to remove precipitated iron species from accumulated distillates and produce additional treated solutions for collection in one or more finish tanks.

A removal device for removing gas bubbles and/or dirt particles from a liquid in a liquid conduit system includes a housing having an entry and an exit and, a main ongoing flow channel which extends through the housing from the entry to the exit, a plurality of branch flow channels, each branch flow channel branching off from the main flow channel at a branch point, at least one quiet zone which is provided at the ends of the branch flow channels, at least one return flow channel for a return flow from the at least one quiet zone back to the main flow channel, where the return flow channel merges with the main flow channel at a merge point, and where the branch flow channels are defined by plates which are curved.

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.

Apparatuses and methods are described herein. An example embodiment may include a balanced diagonal sludge removal assembly configured for use in a basin, the balanced diagonal sludge removal assembly including a discharge pipe, a collection pipe configured to slideably receive the discharge pipe, one or more header pipes extending from the collection pipe to define a first sludge communication path between the one or more header pipes and the collection pipe, and one or more balancing diagonals extending between the collection pipe and the one or more header pipes to define a second sludge communication path between the one or more header pipes and the collection pipe, wherein the one or more balancing diagonals balance flow distribution throughout the one or more header pipes.

An extrusion system for separating soil entrained in wash water, e.g. from harvesting tuberous produce, includes a settling tank configured to receive a flow of soiled water, to allow soil to settle by gravity, and to allow clarified water collection at the top. A diffuser suspended within the tank converts the flow of soiled water into multiple transverse flows to avoid churning the settled soil. A sensor detects the level of settled soil reaching a predetermined setpoint, and in response the system actuates an auger and opens a pinch valve to force concentrated soil from the bottom of the settling tank.

The invention in at least one embodiment includes a system for treating water having an intake module, a vortex module, a disk-pack module, and a motor module where the intake module is above the vortex module, which is above the disk-pack module and the motor module. In a further embodiment, a housing is provided over at least the intake module and the vortex module and sits above the disk-pack module. In at least one further embodiment, the disk-pack module includes a disk-pack turbine having a plurality of disks having at least one waveform present on at least one of the disks.

A sludge treatment system with sludge drying acceleration function includes at least one sedimentation tank, at least one sludge pipe, and at least one group of hydroponic plant. The at least one sedimentation tank is disposed at the downstream of a reservoir. The at least one sludge pipe is disposed in the at least one sedimentation tank for leading the sludge into the at least one sedimentation tank through a leading method, such that the sludge in the at least one sedimentation tank is divided into a water layer and a mud layer. The at least one group of hydroponic plant is planted in the water layer of the at least one sedimentation tank, such that the growth of the at least one group of hydroponic plant accelerates the sludge drying process in the sedimentation tank.

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 bearing housing includes a hollow shell with opposite ends having coaxial openings for at least one bearing element at each end thereof. The shell between the openings has, when assembled in position for use, a bottom with a bottom surface, the bottom having an oil outlet and the bottom surface having an oil outlet opening. The cavity for impurities is arranged below the bottom surface of the shell, and the cavity is arranged in flow communication with the oil outlet and the oil outlet opening.

To move a filter along a manifold assembly the filter may be seated on a moveable shuttle assembly. Seating the filter on the shuttle assembly may include mating a key portion on the filter with a key portion on the shuttle assembly, each key portion corresponding to a filtration characteristic of the filter. The shuttle assembly and the seated filter may then be moved between a first position, wherein the key portions of the filter and the shuttle assembly are mated to one another and first and second fittings of the filter are spaced from first and second fittings of the manifold assembly, and a second position, wherein the key portions of the filter and the shuttle assembly are mated to one another and the first and second fittings of the filter sealingly engage the first and second fittings of the manifold assembly.
