Slurry feed containing solid CaCO3 with NaOH and solution H2O washed with pure water. The ratio of the mass of the feed to the washing water is 1/1. The feed sludge consists of (mass fraction): 10% CaCO3, 10% NaOH, and 80% H2O. The washed sludge is expected to contain 20% solids CaCO3, and 80% solution. The solution carried by the mud has a concentration equal to output solution. Sketch and solve this mass balance problem.
