What is the bod concentration at the outflow of the pond

Reference no: EM131258643

A pond is used to treat a dilute municipal wastewater before the liquid is discharged into a river. The inflow to the pond has a flow rate of Q = 4,000 m³ day^-1 and a BOD concentration of C_in = 25 mg L-1. The volume of the pond is 20,000 m³. The purpose of the pond is to allow time for the decay of BOD to occur before discharge into the environment. BOD decays in the pond with a first-order rate constant equal to 025 day^-1. What is the BOD concentration at the outflow of the pond, in units of mg LT^-1?
