4-20mA Aeration Control Online Dissolved Oxygen Controller

In sewage treatment, the energy required for aeration accounts for about 60% of the total energy consumption. Under the increasingly stringent safety regulations, controlling the energy consumption during the aeration process is the key to energy saving in factories. Some survey results show that electricity can be saved when controlling air volume using dissolved oxygen as an indicator. Therefore, air volume control through high-precision monitoring and maintenance of dissolved oxygen concentration is a significant energy-saving method for aeration systems. For factories, a set of online dissolved oxygen analyzers with fast response and low equipment maintenance costs are crucial to saving energy consumption. It is relatively common to use aerobic microorganisms to treat industrial wastewater, and aerobic microorganisms must decompose organic matter into carbon dioxide, water, and nitrates under aerobic conditions. In the activated sludge process for treating indus…
