10 tons/h of day seashore sand containing 1% by weight of salt is to be washed with 10 tons/h of freshwater running countercurrent to the sand through two classifiers in series. Assume perfect mixing of sand and water occurs in each classifier and that the sand discharged from each classifier contain one part of water for every two parts of sand by weight. If the washed sand is dried in a kiln, what % of salt will it retain? What wash rate is required in a single classifier in order to wash the sand equally well?
