Copper $($Cu$2+)$ waste $($pH $<3)$ is generated metals processing facility at Rate of $0\mathrm{.}3$ ft cubed$/$s$.$ Designsystem to remove copper in wastewater to below its maximum contaminant level of $2\mathrm{.}4$ mg$/$L using lime$.$ Assume there are constituents in the wastewater. Determine target pH and why, volume of rapid mix tank and flocculation tank, and surface area of tank for design and show all work.
