Commercial 1000mg/g Iodine Value Coal Granular Water Purifier
Kinetically, the adsorption rate of organic impurities and the
dechlorination rate of ACs goes up rapidly as the
particle size goes down. This kinetic effect is utilized in making
carbon blocks for POU and POE markets. Ca-
rbon blocks are manufactured from so-called fine-mesh AC that are
typically 10 to 15 times smaller in particle
size than the GAC used in municipal water filters.
For small POU AC systems, such as faucet mounted and pitcher
devices, 20 x 50 mesh size GAC is preferred.
This small size provides fast kinetics for adsorption of impurities
and chlorine removal, while maintaining an ac-
ceptable pressure drop. Larger POE systems use 12 x 30 or 12 x 40
mesh size. This larger particle size still al-
lows for fast kinetics and an acceptable pressure drop, while more
easily covering a large area. Both forms of
GAC and EAC can be thermally reactivated after they are spent,
whether for cost savings or for ecological ben-
efits and waste minimization.
