1.2. A $ 3.78 \times 10^{7} \mathrm{~L} / $ day wastewater treatment plant's influent and effluent concentrations of heavy metals are as follows: Concentration of the Metal \begin{tabular}{lll} Metal & Influent (mg/L) & Effluent (mg/L) \\ Cd & 0.012 & 0.003 \\ Cr & 0.32 & 0.27 \\ Hg & 0.070 & 0.065 \\ Pb & 2.42 & 1.26 \end{tabular} The plant produces a dewatered sludge cake at a solids concentration of $ 22 \% $ (by weight). Plant records show that $ 45,000 \mathrm{~kg} $ of sludge (wet) is disposed of on a pasture per day. Sludge disposal on land is restricted only to sludges that have metal concentrations less than the following. ``` Maximum allowable Metal Concentration (mg metal/kg dry sludge) Cd 15 Cr 1,000 $ \mathrm{Hg} \quad 10 $ $ \mathrm{Pb} \quad 1,000 $ ``` Does the sludge meet quality standards? (a) Assume that the flowrate of solids into the plant is negligible compared to the influent flow rate. Check to see whether this is a valid assumption (13). (b) Assume that the density of the sludge is about that of water, so that 1 kg of sludge represents a volume of 1 L . Check to see whether this is a valid assumption (7).
