Given the data below, produced from a laboratory thickener test - where a sample of mine waste and an industrial flocculant was tested, figure out the appropriate size for an industrial thickener. The slurry contains 40% solids by weight (density = 2.9 g/cm^3). And the thickener is to be designed to treat 10,000 tonnes/day of this slurry, producing a 70% solid by weight underflow. The laboratory settling is done in a 2L cylinder, with an initial height of 50 cm. a. Calculate the required diameter using the Talmage and Fitch method. b. Calculate the required diameter using the Oltmann method. Time (min) 0 2 Interface Height (cm) 50 48 4 46 6 44 8 10 13 17 22 42 40 38 36 34 32 28 40 55 30 28 85 26 24 150 240 23
