b) A slurry containing 3.kg and water kg of solids is to be thickened to a sludge containing 0.75kg of water //kg of solids in a continuous Operation. Laboratory test using five different conc of slurry yielded the following result. Cone (kg water/kg of solids) 3.5 2.8 2.3 1.7 1.1 Rate of sedimentationis 0.20 0.12 0.094 0.074 0.05 Calculate minimum area of thickener to effect separation of 0.5kg//s of solids.
