May 2017. Chemical oxygen demand (COD) is a critical waste treatment measurement in everything from municipal systems to food manufacturing waste streams. Performing COD testing the right way is important in determining wastewater treatment effectiveness and can help diagnose any problems in treatment. In this blog, we’ll cover what chemical oxygen

The 0-150 mg/L range vials (B1010) measure the decrease in the dichromate ion and are measured at 420nm while the 0-1500 mg/L range vials (B1015) measure the amount of chromic ion produced and are measured at 620nm. How do I dispose of my COD
Biochemical oxygen demand (BOD) is the amount of dissolved oxygen needed by aerobic biological organisms in a body of water to break down organic material present in a given water sample at certain temperature over a specific time period. The term also refers to a chemical

TNT820 provides a result in the Ultra Low Range of 1 - 60 mg/L COD and is often used for Chemical Oxygen Demand measurement in wastewater effluent. Hach TNT820 does not require a separate blanking vial for further waste reduction and is compatible with our
This study proposes a modification to the standard method for the determination of the chemical oxygen demand of samples with a salinity up to 40 g NaCl/L and low organic concentrations (20-230 mg
In environmental chemistry, the chemical oxygen demand (COD) 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 ( mg / L ).
