2018/11/01 · COD value is usually expressed in milligrams per liter of water (mg/L). The Significance of Chemical Oxygen Demand High chemical oxygen demand in water indicates greater levels of oxidizable organic matter and consequently, a lower amount of Dissolved Oxygen (DO).

The vials and caps of the COD reagents have been designed to avoid accidental reagent spills. Due to the pre-dosed reagents, the amount of chemicals and handling time is also minimized. Comparison of Methods EPA - The EPA

able to completely oxidize most organic compounds in water. Generally, CODCr is applied in surface waters (e.g. lakes and rivers) and wastewater, and CODMn is applied in lightly polluted waters, e.g. reservoir, tap water and
