14/10/2010, · The COD test uses a chemical (potassium dichromate in a, 50% sulfuric acid, solution) that “oxidizes” both organic (predominate) and inorganic substances in a wastewater sample, which results in a higher COD concentration than BOD concentration for the same wastewater sample since only organic compounds are consumed during BOD testing.

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 …

CHEMSCAN - Welcome to ChemScan Inc.

The Plant City Water Reclamation Facility uses about half of its 10 MGD average treatment capacity, but 14% of the flow into the facility is from industrial sources. The plant was upgraded for Total Nitrogen and Total Phosphorous removal and very stringent Water Reuse standards between 2004 to 2008. During that same period, the plant installed dual ChemScan Process Analyzer Systems to help ...

Treatment of highly acidic wastewater containing high ...

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.

What are the ways of COD reduction in industrial waste water?

in our case, the waste water has high COD and extremely acidic (Sulfuric Acid) also in large scale (nearly, 2000 kg/h)

Wastewater Training & Troubleshooting-COD vs. BOD
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.
