Sedimentation Rate Determination

  • Sedimentation Rate (Sed Rate): ESR Test Results High vs. Low

    The sedimentation rate-- or "sed rate," for short -- is a blood test that checks for inflammation in your body. It's one clue for your doctor that you might have a disease linked to .

  • 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.

  • Calculation of the sedimentation rate applied to your case

    As a result, an elimination rate of 80 to 90% is frequently applied. For a low load wastewater, the sedimentation rate generally used is 0.4 m/h. This makes it possible to calculate the required tank area. For example, for a flow rate of 14 m3/h, a surface area of 35 m² is required. Different types of tanks

    An erythrocyte sedimentation rate (ESR) is a type of blood test that measures how quickly erythrocytes (red blood cells) settle at the bottom of a test tube that contains a blood sample. Normally, red blood cells settle relatively slowly. A faster-than-normal rate may indicate inflammation in the body. Inflammation is part of your immune .
