Explanation of methods to lower COD and how to measure COD!

COD (Chemical Oxygen Demand) refers to the degree of pollution caused by organic matter (contaminants) in marine and lake environments, represented by a numerical value. A higher COD indicates a greater amount of organic matter (contaminants) in the water, meaning that there are more substances that readily react with oxygen present. BOD (Biochemical Oxygen Demand) is often confused with COD. While both are indicators of water pollution, there are key differences: COD: Represents the degree of pollution in lakes and marine areas, measured using oxidizing agents. BOD: Represents the degree of pollution in rivers, measuring the amount of oxygen consumed by microorganisms over five days. *For more detailed information, please refer to the related links. Feel free to contact us for further inquiries.

Hanna Instruments was born in Italy and is now a measurement instrument manufacturer headquartered in the United States, producing and selling various measuring instruments such as pH meters, conductivity meters, residual chlorine meters, and ion meters. It leads the world in the field of water quality measurement and has grown to become one of Europe's leading electronic analyzer manufacturers. In particular, the pocket-sized pHep product has revolutionized pH measurement, which previously relied on litmus paper, by making it easy to handle with digital display, and has become synonymous with 'pH meter' in Europe. All products are certified with the CE mark (indicating conformity to legal regulations in the European region), and the manufacturing facility is ISO 9001:2008 certified, ensuring that we provide products manufactured to strict quality standards. Our primary goal is to provide cutting-edge technology in user-friendly products, and we strive daily to develop products that meet our customers' needs.
