Activated carbon with both micro- and meso pores is needed.
1. A wider pipe
2. A longer pipe
It is not possible to have a pipe narrower than 38 mm, because this would create a “wall effect” in the carbon bed, where impurities escape filtration along the wall of the pipe. If we increase the width of the pipe, the alcohol volume per hour is increased without
Using the method I describe and a Prestige activated carbon or another carbon of the same capacity, one can often filtrate much faster then 0.25 HSV.
