In the Bayer Process, red mud solids are separated from water using a clarifier cascade. Each clarifier in the cascade removes 65.0 w/w% of the water from the red mud stream entering it. The feed of red mud into the first clarifier of the cascade is 550 kg/h of red mud, containing 40.0 w/w% solids (the remainder being water). Wet solids (red mud) Water Clarifier 1 Water Clarifier 2 Water Clarifier 3 Dried red mud a) What is the flowrate of dried red mud exiting the cascade? b) How much water remains in the dried red mud? c) If the water which is removed contains 0.15 M NAOH leftover from the digestion process, how much 1.0 M HCI is required to neutralize it in a separate reactor, assuming the density of both the water/NAOH and HCI streams is the same as water (1000 kg/m')?
