1. Core positioning: A comprehensive assessment instrument for oxygen consuming organic and oxidizable inorganic pollutants in water bodies.
2. Technical core: Simulate laboratory standard procedures, automatically add a quantitative amount of potassium permanganate under acidic conditions, heat and digest the reaction, determine the remaining amount through titration or photometry, and calculate the consumption. Programmed control throughout the entire process.
3. Customer value: Provide important comprehensive indicators of organic pollution in water bodies (similar to COD but applicable to cleaner water bodies). It is an important tool for evaluating drinking water sources, surface water environments, and effluent quality from sewage treatment plants, meeting environmental regulatory requirements.
4. Typical applications: monitoring of drinking water sources, automatic monitoring stations for surface water such as rivers and lakes, sewage treatment plant outlets, and process control of water treatment plants.
