If the inlet concentration is decreased to 1 ppm, then the estimated filter life
will be increased by an average factor of 5. Likewise, if the inlet
concentration is increased to 25 ppm, then the estimated filter life will be
decreased by an average factor of 2. Experience with routine use will
establish a predictable filter life that is representative of your specific
chemical work.
Impregnated Carbon Filter Life
To estimate impregnated carbon filter life for acids, formaldehyde-formalin,
and ammonia, use the following chart below. The values in the chart below
are expressed in weight (grams) and volume (milliliters) which can be used to
estimate Filter Life from a known usage.
For example, you estimate that 37% hydrochloric acid is being used at 500
ml per week and want to know how to program the Filter Life timer for a 3'
Paramount. A 3' Paramount uses 40 pounds of impregnated carbon at 17%
estimated life before saturation. 17% of 40 pounds is equivalent to 3060
grams of available carbon. There are 424 g/L of hydrochloric acid in a 37%
solution. Thus, there are 3060 grams/424 g per L or 7.2 Liters (7200 ml) of
hydrochloric acid before saturation. Assuming there are 10 hours of use per
week at 500 ml per week, the expected Final Life is programmed at 140
hours and the Check Life is programmed at 40 hours and it comes from the
following calculation:
(7200 ml/500 ml/week) * 10 hours/week = 144 hours, rounded to 140 hours
37% Hydrochloric Acid
67% Nitric Acid
96% Sulfuric Acid
37% Formaldehyde or Formalin
50% Ammonia Solution
