Sediment Control and Removal SystemsSee All Air & Water Remediation
Mobile and emergency solutions for sediment control for applications like check dams, sand bags, sediment ponds, silt fences, straw barriers and more.
The Oxford Dictionary defines sediment as “particulate matter that is carried by water or wind and deposited on the surface of the land or the seabed, and may in time become consolidated into rock.” Controlling sediment that falls within this meaning requires using sediment removal systems to control water that runs across the soil and carries soil particles with it. This is commonly done by installing structures to capture the particle. This includes check dams, sand bags, sediment ponds, silt fences, and straw bale barriers.
Evoqua's ProAct™ services frequently works on sites where sediment control systems are used. Typically, these are installed by other contractors or by the customer. However, ProAct services will do whatever it takes to make a job successful. At times, this has included installing sediment control devices.
The Oxford Dictionary also offers this other definition of sediment: “matter that settles to the bottom of a liquid; dregs.” ProAct services deal with sediment in this sense when using gravity to allow solids to settle out of contaminated water. The elements needed are still water and time.
Typically, a weir tank or frac tank is used to hold water for up to twenty-four hours to allow solids to settle out. Sometimes a specially-designed settling tank is used. These low-energy system components have few moving parts. After settling, the water is pumped out and the sludge is retained for separate handling.
Often a settling tank or weir tank is the first in a series of treatment components, and the pumped water may go through a number of different processes, such as solids removal or pH adjustment, before being discharged. Evoqua can design, provide and operate a treatment system to meet your project needs.
