ISE Online Ammonia Nitrogen NH4-N Controller for Sewage

Ammonia nitrogen and nitrate nitrogen are the most important nitrogen-containing pollutants in water. Due to the increasing serious eutrophication of water bodies, sewage treatment plants have increasingly strict requirements for nitrogen removal. Biological nitrogen removal has become one of the primary considerations in municipal sewage treatment processes. At the same time, from its own perspective, the sewage plant urgently needs to reduce operating costs by reducing fan energy consumption and other means. Therefore, on the premise of meeting the emission standards regulated by regulations, the energy consumption of the blower and the consumption of chemicals can be more accurately controlled to achieve the purpose of controlling operating costs. The DUC2-NH online ammonia nitrogen controller developed and produced by Daruifuno has two SPST relays and two 4-20mA current outputs, which can more accurately control equipment such as blowers and control the ammonia nitrogen content in water quality. This ammonia nitrogen controller is equipped with an ammonia nitrogen sensor using the ion selection method, which is very suitable for process control of denitrification in biological ponds. Usually, the aeration system in a municipal sewage plant uses online monitoring values such as dissolved oxygen, sludge concentration, ammonia nitrogen, and nitrate nitrogen in the biological pool to accurately control the air volume provided by the fan to save energy consumption. A reliable ammonia nitrogen analyzer plays an important role in automatic control.

Delfino company focuses on the research, development and production of water quality instruments. Our main products include Ph Orp Analyzer, Conductivity Analyzer, Turbidity Analyzer, Cod Analyzer, Dissolved Oxygen Analyzer, ammonium analyzer, chlorine analyzer, etc. This online ammonia nitrogen controller combined with NH351 ammonia nitrogen sensor is an electrochemical method using ionophores. A significant advantage of this method is that it greatly reduces the size of the analysis equipment. Ammonia nitrogen data can be obtained in real time through a sensor and controller. The cost is lower than that of traditional wet chemical analyzers, and it can be used on a large scale in sewage plants and other occasions. use.
