Sedimentation Rate Sediment

Sedimentation Rate - eMedicineHealth

The sedimentation rate is also called the erythrocyte sedimentation rate because it is a measure of the speed that the red blood cells (erythrocytes) in a tube of blood fall to the bottom of the tube (form sediment). Sedimentation rate is often abbreviated as sed rate or ESR.

Basic Theory of Particle Size Analysis by Sedimentation

rate of sedimentation for small particles is too low to give a practical analysis time, and because Brownian motion of small particles becomes too large to allow effective settling. A very narrow distribution of small particles will be reported as a broad distribution when the rate of particle diffusion is comparable to the sedimentation rate.

The erythrocyte sedimentation rate (ESR) is a commonly performed test but is very nonspecific, which means that having a high ESR does not necessarily tell your physician what is wrong, only that something may be wrong. The ESR is a marker of inflammation, so it can be high with infections and also other types of inflammation.

Sed rate (erythrocyte sedimentation rate) - Mayo Clinic

Erythrocyte sedimentation rate (ESR or sed rate) is a test that indirectly measures the degree of inflammation present in the body. The test actually measures the rate of fall (sedimentation) of erythrocytes (red blood cells) in a sample of blood that has been placed into a tall, thin, vertical tube.

Sedimentation (water treatment) - Wikipedia

Sedimentation is a physical water treatment process using gravity to remove suspended solids from water. Solid particles entrained by the turbulence of moving water may be removed naturally by sedimentation in the still water of lakes and oceans. Settling basins are ponds constructed for the purpose of removing entrained solids by sedimentation.

SEDIMENTATION - MRWA.com

When water temperature decreases, the rate of settling becomes slower. The result is that, as the water cools, detention time in the sedimentation tank must increase and the operator must make changes to the coagulant dosage to compensate for the decreased settling rate. In most cases, temperature does not have a significant effect on treatment.
