During an experiment of a sample solution conducted on a constant pressure plate and frame filter, 400 cm3 of filtrate was collected in 30 secs., and a total of 700 cm3 was collected after another 40 seconds. The density of the solids is 2000 kg/m3 and 1200 kg/m3 for the filtrate. The P&F has total area of 100 cm2. The same type of feed at 35% (wt.) slurry is to be filtered on a rotary drum of 3 m mean diameter and 6 m long. The filter material which is 32 mm thick is the same as the experiment, as well as the operating pressure. Upon observation, the drum is 26% submerged on the slurry. What is the feed rate to the rotary drum filter in kg/s?

Question

During an experiment of a sample solution conducted on a constant pressure plate and frame filter, 400 cm3 of
filtrate was collected in 30 secs., and a total of 700 cm3 was collected after another 40 seconds. The density of
the solids is 2000 kg/m3 and 1200 kg/m3 for the filtrate. The P&F has total area of 100 cm2.

The same type of feed at 35% (wt.) slurry is to be filtered on a rotary drum of 3 m mean diameter and 6 m long. The filter material which is 32 mm thick is the same as the experiment, as well as the operating pressure. Upon observation, the drum is 26% submerged on the slurry. What is the feed rate to the rotary drum filter in kg/s?
