The disclosure includes a process and a plant for separating a suspension C from a suspension A, wherein the fraction of particles P.sub.C in the suspension C, which have a diameter smaller than a defined limit grain diameter, is greater than in the suspension A by at least the factor of 2. The suspension A is introduced into a container extending from the bottom to the top and a suspension B is withdrawn from the container, whose fraction of particles with a diameter greater than the defined limit grain diameter is increased with respect to suspension A. Due to the fact that suspension C is withdrawn from the container in a second partial stream above the first partial stream, in that the flow velocity of the suspension C is greater than the sinking velocity of the particles P.sub.C contained therein, an effective separation can be achieved.

A settling basin insert for controlling fluid flow into a settling basin has a first and second side wall in opposition, and a top surface extending between the first and second side walls, defining a sump extending from head to end. Fluid apertures extend through the top surface to permit fluid to communicate with the sump and an access aperture in the top surface permits a vacuum hose to pass into the sump. The first side wall is taller than the second side wall, and the first and second side walls each define a guide wall extending above the top surface. The second side wall is configured to be adjacent the settling basin. The first and second side walls direct inflowing fluid along the settling basin insert and through the fluid apertures in the top surface, decelerating the fluid for settling of sediment in the settling basin insert.

Provided are: a lid capable of capturing a foreign substance from a liquid crystal material in advance before the liquid crystal material is used; and a method of capturing a foreign substance. In a lid (20) including a bottom part (22) closing an opening on one end of a circumferential part (21) having a tubular shape is provided and a circumferential part (21) placed over a tubular part having an opening of a container provided at the container, the bottom part (22) covering the tubular part, the lid further includes a partition board (211) provided at an inner surface of the circumferential part in a slanted direction against the bottom part (22) and dividing the inside of the circumferential part (21) into a first space proximal to the bottom part (22) and a second space apart from the bottom part (22), and a connection part (213) which connects the first space with the second space being provided at a portion of the partition board (211) closest to the bottom part (22).

Relating to a technology for separating a suspended matter in a suspension using ultrasonic waves, a technology that can realize high separation ability capable of highly efficient separation of the suspended matter in the suspension is provided. A suspension flow-through separation apparatus includes a flow-through separator including a flow-through separation unit. The flow-through separation unit includes a cavity structure that functions as a channel through which a suspension flows, a side surface portion which extends in an x-direction of the cavity structure, a supply port which is provided at one side surface portion, an outlet port which is provided at the other side surface portion, two planar portions that extend in a y-direction in the cavity structure and face to each other, and an ultrasonic oscillator that is provided at least one of two planar portions, and emits ultrasonic waves to the channel. The suspended matter in the suspension is captured by the ultrasonic waves and separated in a z-direction that is a vertical direction while the suspension flows through the channel of the flow-through separator. A first angle formed by the x-direction or the y-direction and a flow-through direction corresponding to a straight line connecting a center point of the supply port and a center point of the outlet port is an acute angle.

A transportable multi-chamber water filtration system useable at construction sites with sources of contaminated water is disclosed. The transportable multi-chamber water filtration system removes sediment and contaminants from contaminated water by combined processes of gravitational settling, filtration and coagulation of sediment by the use of flocculants. The system provides efficient removal of sediment and contaminants from the water around various sized sites.

Fluid apertures extend through the top surface to permit fluid to communicate with the sump and an access aperture in the top surface permits a vacuum hose to pass into the sump. The first side wall is taller than the second side wall, and the first and second side walls each define a guide wall extending above the top surface. The second side wall is configured to be adjacent the settling basin. The first and second side walls direct inflowing fluid along the settling basin insert and through the fluid apertures in the top surface, decelerating the fluid for settling of sediment in the settling basin insert.

A separator for an oil well produced fluid comprises a housing and a tube group arranged within the housing. The tube group includes a plurality of horizontal pipes in a layered arrangement along a vertical direction, and a plurality of vertical pipes which allows adjacent layers of the horizontal pipes to be in fluid communication with each other. The plurality of horizontal pipes shares an inlet pipe in communication with the outside of the housing, and each of the horizontal pipes has a respective outlet. The separator is configured in such a manner that the horizontal pipes in an upper layer, a middle layer, and a lower layer are respectively used as oil pipes, water pipes, and sediment pipes.

The present disclosure relates to a device for removing particulates, such as sand, from a fluid at an oil and/or gas wellsite. In one aspect, a vessel for separating particulates from a fluid is provided. The vessel includes a body having an inlet and an outlet. The vessel also includes a first chamber and a second chamber disposed in the body. The vessel further includes a screen configured to separate particulates from the fluid. The screen is disposed in the second chamber. Additionally, the vessel includes a vessel door for inserting and removing the screen from the second chamber. In another aspect, a pressure vessel for separating particulates from a fluid is provided. In yet a further aspect, a method of separating particulates from a fluid is provided.

A material separation system and method is disclosed. The system may include a buoy having a volume that includes or houses a reacting component. The buoy may be placed in a container to hold the material to be separated during a separation procedure. The separated material may be used to various procedures following separation.

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.
