1/10/2017, · The wastewater was highly acidic with extremely, high COD., The overall process was optimized over various parameters like current density (A/m 2), electrode gap and H 2 O 2 dosage. Moreover,, COD, degradation, specific energy consumption, and operating cost were calculated for the overall treatment process.

Wastewater Training & Troubleshooting-COD vs. BOD

Almost all wastewater treatment plants are required to measure one of these three items as a measure of the pollution value in the water. COD should always measure higher than TOC and then BOD. COD or Chemical Oxygen Demand is the total measurement of all chemicals in the water that can be oxidized.

Chemical oxygen demand - Wikipedia
Chemical oxygen demand - Wikipedia

In environmental chemistry, the chemical oxygen demand is an indicative measure of the amount of oxygen that can be consumed by reactions in a measured solution. It is commonly expressed in mass of oxygen consumed over volume of solution which in SI units is milligrams per litre. A COD test can be used to easily quantify the amount of organics in water. The most common …

BOD Vs COD | What Is BOD | What Is COD

• COD measurements are usually made with samples of waste water or natural water, which are contaminated by domestic and industrial waste. • A closed water sample is incubated with a strong oxidizer such as potassium dichromate (K2Cr207) in combination with boiling sulfuric acid (H2SO4) at a specific temperature for a specified period of time.
