About this document
DO Sag Equation Derivation by Hemanth is a document available to read on EtoBox.
The document describes the derivation of the dissolved oxygen sag equation, which models the change in dissolved oxygen concentration over distance downstream from a wastewater discharge. It begins by setting up an oxygen mass balance and reaction rate equations for biological oxygen demand and reaeration. These are combined into a differential equation and solved using integrating factors to obtain the Streeter-Phelps or DO sag equation. The equation is then used to determine the critical point of minimum
