An in-line fitment for connection of a filter to a pipe includes first and second fluid-carrying portions and a non-fluid-carrying spacer. Each fluid-carrying portion includes a socket for receiving an open end of a pipe and a connector for connection of the filter. A screw compression fitting is provided on each of the sockets of the first and second fluid-carrying portions for forming a sealed connection with the open ends of the pipe. The socket of the first fluid-carrying portion has a pipe receiving depth greater than that of the socket of the second fluid-carrying portion for enabling movement of the fitment parallel to the pipe when engaged with one of the open ends of the pipe. The sockets of the first and second fluid-carrying portions are positioned on a common axis and facing away from each other when the fluid-carrying portions are linked by the spacer.

Fluid treatment systems and components are provided for a removal of solid matter from water or other fluids in which a chemical or chemicals may be introduced into the fluid under pressure to coagulate and/or conglomerate the solid materials and cause them to be dropped out of the treatment system and be removed. The fluid treatment system can include: an equalization chamber receiving a wastewater; a clarification chamber receiving a partially separated water from the equalization chamber; a mixing tube having an inlet end and an outlet end; and a sludge detector.

A separator, for separating solids from a liquid, comprises a hydrodynamic separator, a first filtration device, a first backwash device, a second filtration device, and a second backwash device. The first filtration device comprises a first inlet at a first level for receiving at least a first portion of the liquid from the hydrodynamic separator, and a first filter for filtering the first portion of the liquid received via the first inlet. During filtration of the first portion of the liquid, the first portion of the liquid passes through the first filter away from the first inlet and a first portion of solids is retained by the first filter. The first filter is located between the first inlet and the first backwash device. The first backwash device is configured to alternately prevent and allow the passage of the first portion of the liquid through the first backwash device such that, when the passage of the first portion of the liquid through the first backwash device is prevented, the first portion of the liquid that has passed through the first filter passes back through the first filter toward the first inlet so as to remove the first portion of solids from the first filter. The second filtration device comprises a second inlet at a second level higher than the first level for receiving a second portion of the liquid from the hydrodynamic separator, and a second filter for filtering the second portion of the liquid received via the second inlet. During filtration of the second portion of the liquid, the second portion of the liquid passes through the second filter away from the second inlet, and a second portion of solids is retained by the second filter. The second filter is located between the second inlet and the second backwash device. The second backwash device is configured to alternately prevent and allow the passage of the second portion of the liquid through the second backwash device such that, when the passage of the second portion of the liquid through the second backwash device is prevented, the second portion of the liquid that has passed through the second filter passes back through the second filter toward the second inlet so as to remove the second portion of solids from the second filter.

A method of concentrating sediment in a water tank involves attaching a vortex inducing device to an opening through the roof of the tank between the central vertical axis and the side walling of the tank. The device has a device inlet which narrows to a device outlet. The device outlet is orientated such that, water flowing out via the device outlet induces a vortex within the pooled water, thereby causing sediment to collect centrally on the floor of the tank.

A sand separator for capturing solid debris from oil and gas wells includes a spherical, high-pressure vessel adapted to couple downstream of a wellhead. Fluid entering the separator follows a helical path around a vertical separator axis, slowing and separating into water, gas, oil and solid debris, the latter sinking to the bottom. A conical, downwardly opening flue descends from an exit port at the top and terminates in a horizontal, coaxial perimeter. A scalloped, annular collar inside the flue perimeter creates a low barrier to fluid flow into the flue. As fluid constituents circulate toward the flue, they recombine free of sand and rock debris, pass under the flue perimeter and across the collar, slowing further and becoming substantially laminar A fluid dome rises inside the flue with a gas layer above other fluid constituents, permitting the gas to exit the separator through the exit port.

A method for purifying an easily polymerizable substance efficiently to improve the troublesome matters when cleaning, e.g., reducing the number of times the metal mesh is cleaned. The method for purifying an easily polymerizable substance of the present invention comprises a step of introducing a crude liquid containing the easily polymerizable substance into a distillation column, and a first separation step of introducing a bottoms liquid extracted from a collection part of the distillation column into a wet cyclone, to separate a first purified liquid containing the easily polymerizable substance from a liquid containing an insoluble solid.

A magnetic filter 10 includes first and second separation chambers 10, 12. The separation chambers 10, 12 each have an inlet and an outlet, and the separation chambers 10, 12 are joined together such that the inlets of the first and second chambers are adjacent, and the outlets of the first and second chambers are adjacent. An inlet port arrangement 28 connects both inlets to a single inlet pipe, and an outlet port arrangement 30 connects both outlets to a single outlet pipe.

A cyclonic inlet diverter for initiating the separation of a multi-phase inlet fluid flow comprises an enclosed tubular body mounted crosswise within a larger separator vessel. The inlet diverter includes a splitter plate positioned within a center portion of the tubular body and configured to split the inlet flow into a first stream and a second stream, and a swirl plate positioned on each side of the splitter plate with angled surfaces configured to increase the cyclonic motion of the first and second streams within the tubular body. The inlet diverter further includes elongate apertures formed through bottom sidewall portions of the tubular body on each side of the splitter plate, an axial aperture formed through opposing end caps of the tubular body, and at least one radial aperture formed through lateral sidewall portions of the tubular body proximate each opposing end cap.

A thickener for dewatering fluids having a vessel with a central well extending proximate a top portion of the vessel to a lower cone-shaped portion, a hindered settling zone, and a compressible sediment layer zone within the lower cone-shaped portion. Eductors housed in inlet wells have an inlet nozzle and a mixing tube to receive slurry to be treated and clear fluid to be mixed with the slurry. The fluid from the eductors is directed in counter circular paths via circular chambers situated proximate the inlet wells, such that fluid flowing in each direction collides and forms turbulence within the central well. Resultant fluid is directed into a lamella-type separator circumferentially located about a portion of the central well, having layered fluid paths directed radially outwards from said center longitudinal axis and upwards towards said vessel top portion through a conical, inclined fluid path, plate structure. The eductors are adjustable with a movable iris for limiting the amount of clear fluid exiting the eductor.
