17/3/2021 · Measuring chemical oxygen demand (COD) is one of the most frequently performed tests for assessing water quality. It is widely applied in municipal wastewater facilities and industrial wastewater treatment plants to determine the degree of water contamination and to evaluate the efficiency of treatment processes.

Chemical oxygen demand (COD) is the amount of dissolved oxygen that must be present in water to oxidize chemical organic materials, like petroleum. COD is used to gauge the short-term impact wastewater effluents will have on the oxygen levels of receiving waters.

Environmental Test Kits. Determine the concentrations of a wide range of gases and chemicals in the environment, whether by air, water, or soil sampling. Portable, convenient handheld units are ideally suited for field analysis of samples. All instruments are easy to use with accurate readings for reliable service.

The chemical oxygen demand (COD) test is commonly used to indirectly measure the amount of organic compounds in water. Most applications of COD determine the amount of organic pollutants found in surface water (e.g. lakes and rivers) or wastewater, making COD a useful measure of water quality. It is expressed in milligrams per liter (mg/L
