Question

Washing of a rotary vacuum filter cake
For the above problem it is desired to wash the product antibiotic out of the cake so that only 5% of the antibiotic in the cake is left after washing. We expect the washing efficiency to be 50%. Estimate the washing time per cycle that would be required.​

Answer 1

p = f(V') at different constant filtration rates v (V~ = 0.02 m3/m2): ---) Pay = f(V'); i) v = 210.10 -6 m/sec; 2) v = 190.10 -6 m/see; 3) v = 170.10 -6 m/see; 4) v = 150.10-6 m/see; 5) v = 140- 10 -6 m/see; 6) v = 130- 10 -6 m/see; 7) Vop t = 123.10 -6 m/sec; and 8) v = 120.10 -6 m/sec.
