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.
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.
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.
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.
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.
(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 â€œsettlingâ€); (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 â€œsettlingâ€).
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.
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 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.
