Thank you very much for sharing! Very nice and clear illustration. Just one comment: it is not very clear to me by saying sulfuric acid oxidizes something, which is different from what is written in the slide (13:29) where the oxidizing agent in the COD measurement is dichromate while sulfuric acid provides the acidic condition (i.e., H+) that allows the reaction to occur.

@@belindasturm352 What happens to the 6 moles of oxygen? You take "180 * 32" but it's 1 mole glu per 6 mole of oxygen. So should you times 32 by 6?

please teach the question, river has average velocity of 0.7m/s and has a reoxygenation constant 0.4 d-1. At the point of which organic pollutant is discharged, it is saturated with oxygen at 10mg/L.. Below the outfall the ultimate demand for oxygen is found to be 14mg/L and the Kr= 0.2 d-1. And Kd =0.14 d-1. What would be the pollutant concentration 8 Km downstream? Mention the assumptions made for solving this problem. Assume if any data is needed. (The Streeter - Phelps equation is given in the last page with usual notations) [
