Sedimentation, or clarification, is a particle filtration process that requires special chemicals (called flocculants and coagulants) and water holding tanks. This filtration process is complex and expensive, and is used to treat large volumes of surface water high in sediments and soil particles like silt and clay.

Formation of sediment. A sediment is a natural deposit created by the action of dynamic external agents such as water, wind, and ice.

The action or process of forming or depositing sediment.

The addition of soils to lakes, a part of the natural aging process, making lakes shallower. The process can be greatly accelerated by human activities.

deposition of material away from it's site of origin. Can be organic or inorganic and usually moved by the action of water, wind, gravity or ice.

means the deposition of sediment, usually in locations such as a channel, along a fence, in an area of low slope or a sediment trap, dam or water body.

see settling.

the process whereby particles (suspended solids) settle out of solution. Sedimentation produces a sludge or other layers of solids at the bottom of a sedimentation, or settling pond.

The removal, transport, and deposition of detached soil particles by flowing water or wind.  Also, the process of solid particles settling out of water and wastewater treatment processes.

The process where material carried in suspension in water, settles out.

The deposition of transported soil particles due to a reduction in the rate of flow of water carrying these particles.

The gravity settling, and thus removal, of materials more dense than the suspending fluid.

Separation of a dense material (usually a solid) from a less dense material (usually a liquid) by allowing the denser material to settle out of the mixture.

_ Soil or gravel transported by water from other streams and bodies of water that settle out of water and are deposited.

A water treatment in which solid particles are settled out of the water in a sedimentation basin or clarifier.

Sedimentation is the process of a material sinking to the bottom of a liquid.

Soil particles, clay, sand, or other materials settle out of a fluid suspension into the bottom of a body of water. Human caused earth-moving activities such as agriculture and construction greatly increase sediment load.

A process in which wastewater is held for a period of time in a tank or basin, during which the heavier solids settle to the bottom.

the deposition of fine material (sand or mud) in the channel.

The accumulation of earthy matter (soil and mineral particles) washed into a river or other water body, normally by erosion, which settles on the bottom. Another use of the word is as a hazardous waste physical treatment method that separates and removes suspended particles that are heavier than the liquid in which they are present by gravitational settling.

The process of transportation and deposition of particles onto the bottom of a body of water.

The settling of solids in a body of water using gravity.

A solid-liquid separation process utilizing gravitational settling to remove soil or rock particles from the water column.

a process, whereby a suspension settles, leaving the upper region depleted of particles and the lower region concentrated. Used in waste water treatment to collect inorgain percipitants and organic flocs.

Process by which solid material settles out of a liquid. Sludge settles out of wastewater in sedimentation tanks.

process in which a substance settles out of a heterogeneous mixture.

process in which suspended particles settle to the bottom

The term means the settling of solids that are heavier than the liquid or gaseous medium surrounding them. To determine the sedimentation value of a flour, the protein of a flour suspension is precipitated (coagulated) using a suitable coagulant (e.g. lactic acid). The height of the protein sediment is then measured after a set time. This is the sedimentation value.

The process whereby sediment settles to the bottom of a streambed or is deposited on the floodplain.

The deposition of organic materials or minerals by chemical, physical, or biological processes.

(1) the process of depositing sediment, or the addition of soils to lakes that is part of the natural aging process; (2) the drinking water treatment process of letting heavy particles in raw water settle out into holding ponds or basins before filtration (also called “settling”); (3) the process used in both primary and secondary wastewater treatment that takes place when gravity pulls particles to the bottom of a tank (also called “settling”).

The process of depositing soil particles, clays, sands, or other sediments that were picked up by runoff.

The process by which particles in water settle at the bottom of a basin or container.

the depositing of sediment from a state of suspension in water or air.

A prefiltering process for removal of solids by gravity or separation.

A treatment process which allows sediment to settle out of water or wastewater.

deposition of material suspended in water or air, usually when the velocity of the transporting medium drops below the level at which the material can be supported.

Floc settles to the bottom of the water.

sedimentation is an increase in the amount of solid particles suspended in water, caused primarily by soil erosion. The main human causes of sedimentation are forestry, farming, and construction. When sediment settles, it can smother the feeding and spawning grounds of fish and kill aquatic organisms.

Action of the settling of the suspended solids.

deposition of solids carried by storm water which accumulate in channel beds, flood plains and the bottoms of lakes and rivers.

describes the process of solid particles settling in a liquid depending on the time

(3) the process or action of depositing sediment.

Buildup of sediment that occurs when materials that are suspended in a river or stream collect behind a barrier such as a dam. This can prevent nutrients from reaching downstream habitats.

Sedimentation occurs when eroded soil is deposited by runoff into rivers, harbors and lakes, degrading water quality and inhibiting navigation

The accumulation of earthly matter (soil and mineral particles) washed into a river or other water body (normally by erosion) that settles on the bottom (UNEP, 1996).

The deposition of eroded material (sediments).

The action or process by which sediment is deposited or settled. The depositing of sediment, especially by mechanical means of manner suspended in a liquid.

A large scale water treatment process where heavy solids settle out to the bottom of the treatment tank after flocculation.

The process that deposits soils, debris and other materials either on the ground surfaces or in bodies of water or watercourses.Silt. (1) Soil fraction consisting of particles between 0.002 an 0.05 mm in diameter. (2) A soil textural class indicating more than 80% silt.

The process of depositing soil, clay, sand, or other sediments that were moved by the flow of water.

The process of removing particulate matter from water or wastewater. This is accomplished in a quiet tank where gravity differences between the particles, or floc, and the water allows settling.

A water treatment process in which solid particles settle out of the water being treated in a large clarifier or sedimentation basin.

The act or process of depositing sediment

The buildup of sediment in the water.

The settling of soil particles (sediment) to the bottom of a waterway.

settling of particulate matter in water related to particle size, water velocity, and water flow.

accumulation or deposition of eroded soil particles or particulate material

the deposition or accumulation of sediment, such as sand, silt, or clay.

The removal of settleable suspended solids from water or wastewater by gravity in a quiescent basin or clarifier.

deposition of fine sediments which can cause clogging of gravel beds

The accumulation of earthy matter (soil and mineral particles) washed into a river, stream, wetland, or other water body, normally by erosion, and which settles on the bottom. The gradual build up of sedimentation tends to choke channels and rivers, inhibiting plant and fish life.

The process of suspended solid particles settling out (going to the bottom of the vessel) of water that has little or no movement.

The sinking of a molecule under the opposing forces of gravitation and buoyancy.

The process in which solid suspended particles settle out of water, usually when the water has little or no movement. Also called "settling".

Sedimentation is a physical water treatment process used to settle out suspended solids in water under the influence of gravity.
