A plating plant has a waste stream containing zinc and nickel in quantities in excess of that allowed to be discharged into the sewer. The proposed process to be used as a first step in reducing the concentration of Zn and Ni is shown in the figure below. Each stream contains water. The concentrations of several of the streams are listed in the table. Complete the table by calculating all with ? In the appropriate units.
