A separation apparatus that includes a weir tank having a plurality of cells and fluid removal apparatus for each cell to remove the fluid from each cell. The fluid removal apparatus includes an actuator and an extension arm whose movement is caused by the actuator. In addition to the actuator and the extension arm, the fluid removal apparatus includes a plunger attached to the extension arm for selectively engaging a first opening in each cell. Furthermore, a method of removing fluid from the separation apparatus via the fluid removal apparatus.

An apparatus and method for a grease trap for separating grease and solid waste from waste water. The grease trap includes a tank having a downwardly shaped bottom. An upwardly shaped baffle insert divides the tank into an upper chamber and a lower chamber. An outlet port near an upper part of the baffle allows waste into the upper chamber. An inlet invert in the tank receives incoming waste water, while an outlet invert removes water from the tank. A removable cover covers the tank and allows access for removal of accumulated grease and solid wastes.

A system and method of cleaning a desanding vessel is provided including determining that sand has settled in the accumulation zone of the vessel, isolating and depressurizing the vessel and introducing a flush or wash fluid into the vessel. The wash fluid is introduced via a flush inlet at or near the process gas outlet of the vessel, and at a purge rate to fluidize sand in the accumulation zone and form a slurry. The slurry is collected from the vessel at a flush outlet downstream from the flush inlet. The purge rate is maintained for elutriation of the fluidized sand in the slurry, through the vessel and out of the flush outlet.

This invention is a foreign substance removal apparatus that removes foreign substances in such a medium as a refrigerant that flows through a circulation path, the foreign substance removal apparatus including: a foreign substance sedimentation unit which is connected to the circulation path and is configured to settle the foreign substances; a foreign substance separation unit configured to separate, from the foreign substance sedimentation unit, the foreign substances settled in the foreign substance sedimentation unit; first pressure open/close means which is disposed on a bottom of the foreign substance sedimentation unit, and is configured to open or close in accordance with pressure inside the circulation path; and a foreign substance discharge pipe which connects the bottom of the foreign substance sedimentation unit and the foreign substance separation unit via the first pressure open/close means.

An improved water-oil separation apparatus with a separation vessel and associated water leg having internal inlet piping that feeds fluids to an engineered degassing boot, having an engineered degassing boot that is more effective in removing entrained gases from the incoming fluid stream, having an umbrella shaped upper baffle instead of an inverted umbrella shaped upper baffle, having an improved oil collection bucket or weir, having a much improved inlet water spiral distribution apparatus, having an improved water leg design, and having a water leg with a functional height that is externally adjustable to make it easier to regulate the oil-water interface level within the separation vessel.

A stormwater vault and a process for servicing the stormwater vault speeds the process of cleaning the stormwater vault. The stormwater vault has a built in liquefaction system for liquefying settled debris in the vault which works together with a sloped or angled floor in the vault and vertical debris cutting spray nozzles. The settled debris is flushed toward the inlet to a vacuum removal line inserted into the vault through an access opening for removing the settled debris from the vault while compacted debris is collapsed by vertically extending water nozzles.

A waste water separation vessel is provided having a wedge shaped body with an internal water containing volume. The body is configured to trap FOG and wastes within the body allowing water to pass through the body. At least one top facing access port to allow access to the internal volume of the body is provided and the wedge shaped body tapers outwardly from top to bottom to define a larger bottom area than a top area. The side walls include vertically oriented strengthening ribs which define intervening indentations, and each lower end of the vertically oriented ribs is connected to a generally horizontal beam which defines closed bottom ends on the indentations. When the vessel is buried in the ground the wedge shaped body and the closed bottom indentations interact with the ground to help oppose any buoyancy forces acting on the buried body.

An aggregate processing system, including a water source, and a vibrating screen device including a plurality of spray nozzles disposed above a screen for spraying wash water onto aggregate during aggregate processing. A strainer device is provided for removing particulate debris from a water wash stream flowing from a water source to the spray nozzles, the strainer device including a filter screen having an angled shape with a convex side facing the strainer inlet and fluid flow path. The strainer is configured to induce turbulent flow for separation of the particulates by gravity, with the filter screen blocking particulates above a given size. In this manner, particulates which may otherwise lead to clogging of the spray nozzles are removed from the wash water stream.

The present invention comprises an impurities or materials trapping apparatus for separating or trapping a selected or unwanted materials such as sediment in a pourable material having sediment therein. The apparatus comprises a body having side walls between a first end and second end defining at least a recessed inner space 42, 104, 204, 286 there between for a pourable material. The apparatus includes at least one raised portion 50, 51, 55, 56, 206, 208 having a highest point, angled walls 26 connected to the side walls 7, 40 202, 220, 282 and at least one drainage aperture 16, 110, 210 located within the side walls 7, 40, 202, 220 282 or angled walls 26, 103, 203, 284. The raised portion is located at one end of the inner space and the angled walls 26 are located at a spaced distance from the raised portion. In one orientation of the apparatus, the side walls or angled walls drain at least a portion of the pourable material towards and though the drainage aperture and down to the raised portion and in another orientation of the apparatus, the drainage aperture is blocked thereby retaining any sediment. The apparatus of the present invention can be formed as part of a container or bottle and/or be part of a cap assembly. Methods of operation are also included.
