Installation of a hydrodynamic separator along an Arizona highway. In civil engineering (specifically hydraulic engineering), a hydrodynamic separator (HDS), also called a swirl separator, is a stormwater management device that uses cyclonic separation to control water pollution.
Advanced Drainage Systems, Inc. (ADS) is a company that designs, manufactures and markets polypropylene and polyethylene pipes, plastic leach field chambers and systems, septic tanks and accessories, storm retention/detention and septic chambers, polyvinyl chloride drainage structures, fittings, and water filters and water separators.

The Barracuda was based on commercially available 'off the shelf' components, but also many refined systems. [10] Its fuselage was constructed entirely from carbon fibre, [6] but also had a greater strength to weight ratio than traditional aircraft materials such as aluminum (the structure of the Eurofighter Typhoon and Boeing 787 Dreamliner were also made significantly out of it).

Spiral separators of the wet type, also called spiral concentrators, are devices to separate solid components in a slurry, based upon a combination of the solid particle density as well as the particle's hydrodynamic properties (e.g. drag).
The Superkavitierender Unterwasserlaufkörper (lit.Supercavitating Underwater Running Body, formerly known as Barracuda) was a German close-range supercavitating torpedo technology demonstrator [1] designed by the Diehl BGT Defence (now Diehl Defence) and developed in cooperation with the German Navy.
These two factors result in better separation of dust particulates. The pressure drop of multiple-cyclone separators collectors is higher than that of single-cyclone separators, requiring more energy to clean the same amount of air. A single-chamber cyclone separator of the same volume is more economical, but doesn't remove as much dust.
Weir on Lake Tecumseh, Virginia. A flow control structure is a device that alters the flow of water in a stream, drainage channel or pipe. As a group these are passive structures since they operate without intervention under different amounts of water flow and their impact changes based on the quantity of water available.
Marine Oily water separator. A gravity plate separator contains a series of oleophilic plates through which the contaminated water flows. The oil in the water coalesces on the underside of the plate eventually forming droplets before coalescing into liquid oil which floats off the plates and accumulates at the top of the chamber.
