Disclosed is an apparatus for the gravitational separation of the first and second liquid phases of a two phase liquid containing predominantly a continuous first liquid phase with a dispersed second liquid phase having a lower specific gravity than the first liquid. The apparatus comprises a tank defining an interior chamber. A feed inlet introduces the two 5 phase liquid into the lower portion of the chamber. The upper portion of the chamber has an upward flow zone through which the two phase liquid rises, with the dispersed second liquid rising more than the first liquid and being separated therefrom due to the second liquid's lower specific gravity. The second liquid forms a floating layer and a conduit directs separated second liquid from the floating layer to a second liquid outlet.

A separation device, system and associated method are provided herein for separation of particulates form a base fluid. The separation device comprises a first microchannel comprising a fluid inlet and a mesofluidic collection chamber. The mesofluidic collection chamber has a first side and a second side, wherein the mesofluidic collection chamber is operatively coupled to the first microchannel on the first side, and wherein the mesofluidic collection chamber comprises a first fluid outlet at the second side, such that the fluid inlet, first microchannel, and first fluid outlet are in fluidic communication via the mesofluidic collection chamber.

Retrofit box systems to maximize operational capacity of inaccessible floors are described. The retrofit box system includes a gate complex that provides fluid communication between an inaccessible floor and a box, and a box to deliver a cleaner to the inaccessible floor and adapted for equalizing pressure when the inaccessible floor is under water while minimizing waste seepage from the retrofit box system. The retrofit box system further includes a power system and a control system to deliver the cleaner to the inaccessible floor and remove waste from the inaccessible floor and the box.

A tool and method clean and drain a water heater tank, removing water and sediment from the tank. An insert tube fits through the hot water outlet port to reach the bottom of the tank interior. A fitting connects the insert tube to a hose extending down the outside of the tank to the floor/ground to a drain or container that is lower than the bottom of the tank interior. After priming the tool by using the cold water inlet flow to fill the tool with water and sediment, the cold water inlet is disconnected from the water heater, venting the tank so that water and sediment are siphoned out of the tank through the tool to empty the tank. The tool and method work without unplugging or disconnecting a clogged water heater drain line, without using a compressor or pump, and without creating a wet, messy environment.

The invention relates to a liquid recovery system for a motor vehicle and to a vehicle including such a recovery system that that includes at least one liquid intake that communicates with a tank and is referred to as the first tank, which is designed to store liquid from the liquid intake and where the liquid intake is arrangeably designed below the vehicle's beltline.

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.

Stormwater pollution prevention systems, vaults, boxes, and methods of treatment systems to capture pollutants from storm water runoff and prevent the conveyance of these pollutants from entering a receiving water body or landscape area. The systems can be part of a local permanent storm water drainage infrastructure, where the system combines both drainage conveyance, multi-level treatment techniques, variable hydraulic capabilities, and easy and inexpensive methods for servicing the systems. The systems can use cartridges, each having either a treatment media or treatment polymer inside, wherein the cartridges can be serviced without requiring anyone to enter into a treatment vault/box.

The present invention is directed to a plate settler cover that prevents algae growth, prevents contamination from organic material, and provides structural support for a user who is standing or walking on the plate settler system. The plate settler covers can either float directly on standing water present in the system or may be structurally supported such that the plate cover is positioned above the surface of the water.

A screening system for solid removal includes a housing and a screen positioned within the housing. A flow inlet is operatively connected to an interior chamber defined by the screen. A sump is downstream from the flow inlet for capturing solids that do not pass through the screen. A flow outlet is downstream from the screen in fluid communication with the flow inlet. A moveable cleaning assembly may be positioned either within a perimeter of the screen, around the perimeter of the screen or both. The moveable cleaning assembly is moveable with respect to the screen.

A method of separating material, such as foam, sludge, oil or grease, at a fluid's surface, by applying acoustic pressure shock waves to the material and the fluid's surface such that acoustic pressure shock waves are propagated in liquid medium of the fluid and in gas medium above the fluid surface.
