Question- Suppose a thickener in a metal plating plant receives a feed of 40 m3/hr of precipitated metal plating waste with a suspended solids concentration of 5000 mg/L. If the thickener is operated in a steady state mode so that 30 m3/hr of flow exits as the overflow and this overflow has a solids concentration of 25 mg/L, what is the underflow solids concentration, and what is the recovery of the solids in the underflow?
