Settling devices for separating particles from a bulk fluid with applications in numerous fields. The particle settling devices include a first stack of cones with a small opening oriented upwardly or downwardly. Optionally, the settling devices may include a second stack of cones with a small opening oriented downwardly or upwardly. The cones may be concave or convex. These devices are useful for separating small (millimeter or micron sized) particles from a bulk fluid with applications in numerous fields, such as biological (microbial, mammalian, plant, insect or algal) cell cultures, solid catalyst particle separation from a liquid or gas and waste water treatment.

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.

This disclosure relates generally to mixing and separating phases of a mixture, and, more particularly, to an integrated apparatus for mixing and separating immiscible fluid phases and method therefor. The apparatus includes an inlet section, a mixing section, a separating section, and an outlet section. The mixing section includes multiple spiral turns for separately introducing the fluid phases of different specific gravity into the mixing section. Each of the spiral turns includes a helical channel followed by a counter-helical channel for enabling mixing of fluid phases. The counter-helical channel changes the direction of flow of fluid phases upon flow of said fluid phases from the helical channel to the counter-helical channel. The separating section extends from the mixing section separates the fluid phases based on specific gravity difference of fluid phases. The outlet section facilitates in separate withdrawal of fluid phases based on the specific gravity of said fluid phases.

A liquid quality system for removing particulates from liquid (e.g., storm-water runoff). The system can include tubular portion (e.g., a manhole). The tubular portion has an inlet and an outlet. The system includes liquid quality device. The liquid quality device includes a partitioning portion. The partitioning portion has a first region including a funnel shape with a sump inlet aperture. The partitioning portion also has a second region including a sump outlet aperture and optionally a sump access aperture. A sump region is located between a base portion and the partitioning portion, wherein a flow of the liquid travels from the inlet in the tubular portion, into the funnel, through the sump inlet aperture, into the sump region, through the sump outlet aperture, and out the outlet of the tubular portion. At least one drag-inducing portion is positioned proximate the tubular portion in the sump region and projecting inwardly towards a central axis of the sump region.

An apparatus for microfiltration and a scalable method for manufacture of an inertial microfluidic device for such microfiltration apparatus are provided. The apparatus for microfiltration includes one or more inertial microfluidic devices, each including a plurality of spirals of a microfluidic channel. At least one of the inertial microfluidic devices is configured to utilize outer wall focusing for high volume fraction microfiltration of particles. In an embodiment, multiple inertial microfluidic devices are connected in sequence for combined inner wall and outer wall focusing. The scalable method for manufacture of the inertial microfluidic device includes micromachining on a polycarbonate-based substrate a rectangular spiral microchannel having one or more input channels and a plurality of output channels configured to utilize high volume fraction outer wall focusing for microfiltration of particles.

Apparatus and a method for cleaning accumulated sediment from storm drain conduits and other large-diameter conduits. A nozzle assembly is arranged to deliver a high-volume flow of water at a pressure high enough to loosen sediment from the interior of a conduit and to propel the nozzle assembly and an associated nozzle feed hose upstream within a conduit being cleaned. Water from the nozzle assembly flushes the sediment downstream and is then collected, partially cleaned, and reused in the nozzle assembly. Mud and clay may be left in the water to increase its specific gravity and viscosity. A self-contained portable and mobile system includes a tank and apparatus for removal of high concentrations of entrained or suspended solids, and a pump and conduits for delivering a high-volume flow of water, containing quantities of suspended solids, to the nozzle assembly.

A system and a method for treating and recycling process water has a cylindrical sedimentation tank and a cylindrical tank for flotation and storage downstream of the sedimentation tank. Water is added to an inlet at the upper part of the sedimentation tank, and treated water is removed from an outlet at the lower part of the flotation tank for recycling. A screw in the sedimentation tank has a major diameter similar the sedimentation tank, which forces water to flow rotationally from the top towards the bottom of the sedimentation tank. A riser between the sedimentation tank and the flotation tank with one end in a lower part of the sedimentation tank, and the other end at an upper part of the flotation tank. A cleaning loop with ozone added is between the tanks, removing water from the flotation tank and returning it to the sedimentation tank.

A separation tank having an interior space for separating gas and water from oil. A column is disposed in the interior space that has a top portion and a bottom portion, the top portion fluidly connected to an inlet, and the bottom portion fluidly connected to an outlet. The top portion of the column is open to the interior space of the tank through a spiral diffuser which includes a plurality of spiral vanes. An oil collector weir is located in the interior space and is fluidly connected to an oil outlet disposed external to the tank. An upper flow diverting baffle is located below the spiral diffuser and a lower flow diverting baffle is provided below the upper flow diverting baffle so that fluid flows from the spiral diffuser downwardly around the two flow diverting baffles. An aerated water dispensing system is associated with the tank and provides microbubbles to the interior space from the lower flow diverting baffle.
