Correct answer
D. Supersaturate d
Explanation
The correct answer is Supersaturate d.
The basic filtration equation is given as dt/dV = (μ/A ΔP). [(α.CV/A) + Rm], where, V is volume of the filtrate; A is the filtration area, a is specific cake resistance, μ is viscosity of the filtrate, and C is the concentration of the solids in the feed slurry. In a 20 minutes constant rate filtration, 5 m3 of filtrate was obtained. If this is followed by a constant pressure filtration, how much more time in minutes, it will take for another 5 m3 of filtrate to be produced? Neglect filter medium resistance, Rm; assume incompressible cake?
During the washing of cake________?
