Question

the filtration process of sludge involves two stages as follows: constant rate filtration with the feed pump in full capacity until the pressure difference reaches 500kN/m. The pressure is then maintained at this level for the remainder for the filtration. The constant rate filtration process requires 800 seconds during which one third of the total filtrate is obtained. Neglecting the resistance of the filter medium, determine the following: The total filtration time. (7% i) The filtration cycle with the existing pump if the time for removing the cake and reassembling the press is 1300s. (8%)

Explanation / Answer

As feed pump operates in full capacity at constant rate filteration process. 1/3rd filetration occurs at constant rate filteration process which takes 800 sec. so total filteration time = 800*3=2400 sec

total filteration cycle with cake removal and reassembling the press = 2400+1300=3700 sec.
