Criterion of activated Carbon Water Filters

The quality of activated carbon water filters main parameters to judge from the following:

　　Moisture (%) ≤ 5

　　Strength (%) (Ball milling) ≥ 90

　　Iodine adsorption (mg / g) ≥ 1000

　　Methylene blue adsorption (mg / g) ≥ 135

　　Phenol adsorption (mg / g) ≥ 120

　　Semi-dechlorination value (cm) ≤ 6.0

　　Stacking density (g/cm3) ≤ 0.5

　　Size does not require

　　pH 4 ~ 11

　　Chloride (%) ≤ 0.5

　　Lead (μg / g) ≤ 10

　　Zinc (μg / g) ≤ 50

　　Cadmium (μg / g) ≤ 1

　　Arsenic (μg / g) ≤ 2
