. A wastewater containing 50 mg/L of phenol was subjected to an equilibrium test to determine the constant in the Langmuir isotherm. One-liter samples were dosed with powdered activated carbon (PAC) in four jars, and when equilibrium was reached the equilibrium concentrations of phenol were analyzed.a) From the results shown below, determine the Langmuir isotherms constants.b) If the wastewater with a flow rate of 0.10 m3/s containing 50 mg/L of phenol is to be treated using PAC to produce an effluent concentration of 0.10 mg/L, calculate the quantity of PAC needed for the operation?
