Prediction of filtration time and washing time. the slurry used in problem 14.2-1 is to be filttered in a plate-and-frame press having 30 frames and 0.873 m 2 area per frame. the same pressure, 46.2 kn/m 2, will be used in constant-pressure filtration. assume the same filter cake properties and filter cloth, and calculate the time to recover 2.26 m 3 of filtrate. at the end, using through washing and 0.283 m 3 of wash water, calculate the time of washing and the total filter cycle time if cleaning the press takes 30 min.
