Waste from a copper plating facility is being discharged into a receiving stream. The waste stream contains 3.5 mg/L copper with a flow of 4.0 x10° L/day. The receiving stream has an upstream flow of 2.6x10 L/day and 0.50 mg/L of copper. Assume complete and instantaneous mixing at the point where the streams meet and that the system is at steady state. a) Draw the stream disgram b) What is the copper concentration in mg/L immediately downstream of the copper plating facility? c) How many kg per day are contributed to the receiving stream by the copper plating facility? d) What percentage of all of the copper mass in the downstream water is contributed by the upstream flow?

Question
Waste from a copper plating facility is being discharged into
a receiving stream. The waste stream contains 3.5 mg/L
copper with a flow of 4.0 x106 L/day. The receiving stream
has an upstream flow of 2.6x107 L/day and 0.50 mg/L of
copper. Assume complete and instantaneous mixing at the
point where the streams meet and that the system is at
steady state.
a) Draw the stream disgram
b) What is the copper concentration in mg/L immediately
downstream of the copper plating facility?
c) How many kg per day are contributed to the receiving
stream by the copper plating facility?
d) What percentage of all of the copper mass in the
downstream water is contributed by the upstream flow?
