The hydraulic retention time, also known as hydraulic residence time or t, is a measure of the average length of time that a soluble compound remains in a constructed bioreactor. Hydraulic retention time is the volume of the aeration tank divided by the influent flowrate: where using SI Units Volume is in [m³] and Influent flowrate is in [m³/h]. HRT is usually expressed in hours. Calculate HRT
