- A small test filtration of Auromycin crystals in an acetone suspension uses a filter medium of negligible resistance. Itgives the following datat (sec)102030V(lit)0.5000.7070.866In finding these data, we have used a filter with 89 cm2 areaand a pressure drop of 2.6 m of water. We now plan to filter amuch larger crop of crystals containing 7300 liters of solventby using a filter of 1.3 m2. However, this larger crop has aconcentration of 0.28 g/100 cm3 solvent, less than that in onetest filtration, which is 0.34 g/100 cm3 of solvent. How longwill it take to filter this new crop at the same pressure drop. |
