Xingyuan Activated Carbon Crusher

The size range of granular activated carbon (GAC) is usually expressed as the sieve sizes, expressed in mm or US Mesh, between which most of the GAC is retained. It is measured by shaking a sample of granular activated carbon through a defined series of sieves. In metric units it is the width between the sieves wires expressed in mm. In the US Mesh system the sieve size number refers to the openings between the sieves wires per inch.

For example; a 8x30 US Mesh activated carbon means at least 93% of the granules by weight are larger than 30 Mesh (0.60mm) and at least 90% of the granules by weight are smaller than 8 Mesh (2.36mm). 12x40 US Mesh (0.42 to 1.70mm), 6x16 US Mesh (1.18 to 3.35 mm).

EFFECTIVE SIZE (ES)

The effective size of granular activated carbon is calculated as the size, expressed in mm, for which 10% by weight of granules are smaller. It is an indicator for the pressure drop and filtration performance of backwashed and segregate carbon beds. A lower effective size will have a higher pressure drop and will filter smaller particles which can result in a higher backwash frequency compared to carbons with a higher effective size.

UNDERSIZE (US) Xinji Xingyuan Biotech Co.,Ltd

The undersize is the amount of activated carbon, expressed in % weight, which is smaller than the finest sieve. (eg % weight smaller than 0.60mm for a 0.60-2.36mm carbon). This quality parameter is often used to determine the potential losses during reactivation.

UNIFORMITY COEFFICIENT (UC)

The uniformity coefficient of granular activated carbon is calculated as the ratio of the size, expressed in mm, for 60% by weight of granules are smaller divided by the effective size. The smaller the uniformity coefficient, the more uniform the particles of the product are. A uniformity coefficient of 1 indicates all the granules have the same size. Granular activated carbons with a low uniformity coefficient are often used when installed in the first step filtration in drinking water production.
