WebJun 15, 2024 · The slowdown of the flowrates is what is known as empty bed contact time (EBCT). EBCT is equal to the volume of the empty bed divided by the flowrate. One cubic foot of activated carbon is equal to 7.48-gallons (28.3-liters) capacity (conversion factor) divided by the flowrate of the filter. For example: 2 cubic feet = 7.481 x 2 / 1.6 gpm = 9. ... WebSep 23, 2024 · It can remove PFAS along with a range of other contaminants at the same time. GAC adsorbents are normally heated to destroy PFAS (usually offsite) and to restore the media’s adsorptive capacity. It is a very effective solution, but its success will depend on the type of carbon used, the Empty Bed contact time (EBCT), flow rate, the nature of ...
