The reactor described in Problem 3 receives 40 L/min of the 1.2 g/L Cu2+ stream. The treated stream (suspended precipitate and all) flows into a sedimentation basin which produces a

sludge stream that is 5% Cu(OH)2(s) by mass. By what percentage did you reduce the volume of the hazardous waste stream? You may assume the density of the sludge stream is 1.04 g/cm3.
