Chemical Oxygen Demand (COD) is defined as a measure of the amount of chemicals usually organic compounds that consume dissolved oxygen in a body of water. It indicates the oxygen required to oxidize both soluble and particulate organic matter present in water. COD is one of the key parameters used to assess the level of pollution in wastewater and natural water bodies such as rivers, lakes, and streams.
The COD value represents the amount of oxygen necessary for the oxidation and breakdown of organic substances into carbon dioxide (COâ‚‚) and water (Hâ‚‚O). In essence, COD testing provides insight into the total quantity of organic and inorganic pollutants present in a sample. A higher COD value indicates higher pollution levels, making COD measurement a critical indicator of water quality.
In the COD test, a strong oxidizing agent such as potassium dichromate is used to oxidize organic matter in the test water sample under acidic conditions. The reaction is typically carried out by digesting the sample at 150°C for about two hours, and the amount of oxygen required is determined from the quantity of oxidant consumed. This method provides a reliable estimate of organic load in wastewater and other water sources.
Pelilab Scientific Private Limited is one of the best COD Analyser Manufacturers in Chennai, delivering advanced, precise, and user-friendly COD digestion systems designed for accurate water quality analysis and long-term laboratory reliability.
Nitroplus 15°C is designed and developed to determine the quantity of oxygen required to oxidize the organic matter in a waste sample under specific conditions of oxidizing agent, temperature and time. Nitroplus 15°C consists of extruded aluminium block and is heated with casted aluminium alloy heater which is very efficient and long life. The temperature of the block is regulated using PID temperature controller with touch screen operation. During digestion, the fumes are refluxed inside Air condensers. Air condensers have ground joint construction for a perfect sealing with the digestion tube and ensures no leakage of fumes during digestion.
The controller can be programmed for time and temperature. All digestion tubes are carried from one place to another using a stainless steel insert rack. A separate rack to keep air condensers when not in use is supplied along with the system. Another rack with stainless steel tank is supplied for the addition of reagents to digestion tubes immersed in water. Â Â
