A manufacturing plant has a wastewater stream that contains 5.15 wt% nickel (Ni) and wants to remove the metal before discharging the wastewater. To do so, they plan to feed the wastewater into a treatment unit that removes 95% of the nickel and recycles it, using it elsewhere in the plant. The treated wastewater is then discharged to lagoon on the property. The treatment unit can treat a maximum of 4500 kg of wastewater per hour. If the plant discharges anything above 4500 kg/hr of wastewater, the excess bypasses the treatment unit and is combined with the treated water leaving the treatment unit and this combined stream goes to the lagoon. Recovered Ni Treatment unit To lagoon Wastewater Bypass a) Appropriately label the process diagram above. b) If wastewater left the plant at 6000 kg/hr., calculate the flow rate of liquid to the lagoon in kg h-1. c) What is the mass fraction of Ni liquid discharged to the lagoon?
