It is desired to filter a cell broth at a rate of 3000 liters/h on a rotary vacuum filter at a vacuum pressure of 70kPa. The cycle time for the drum will be 60 s and the cake formation time (filtering time) will be 20 s. The broth to be filtered has a viscosity of 2.0 cP and a cake solids (dry basis) per volume of filtrate of 10 g/liter. From laboratory test, the specific cake resistance has been determined to be 9 x 1010 cm/g. Determine the area of the filter that is required.

Answer:

0.5667 m^2

Explanation:

Given data :

Flow rate = 3000 liters/h

vacuum pressure = 70 kPa

cycle time for drum = 60 s

cake formation time ( filtering time ) = 20 s

Broth viscosity = 2.0 cP

Cake solids per volume = 10 g/liter

specific cake resistance = 9 * 10^10 cm/g

Calculate the area of filter required

Area of filter required = 0.5667 m^2
