DUC2-NH4 Online Digital NH4-N Ammonium Controller
2 year ago
Product details
Ammonia nitrogen refers to the total nitrogen content of ammonia and amino compounds in water. In the process of sewage treatment, ammonia nitrogen is a very important indicator, because it can reflect the degree of decomposition of organic matter and the content of nitrogen in sewage. Therefore, sewage plants need to monitor the value of ammonia nitrogen to ensure the quality and effect of sewage treatment. In the sewage treatment process, the monitoring of ammonia nitrogen is mainly concentrated in the water inlet, water outlet and various links in the treatment process. At the water inlet, monitoring the value of ammonia nitrogen can help the sewage plant understand the content and pollution degree of pollutants in the raw water, so as to carry out targeted treatment. At the water outlet, monitoring the value of ammonia nitrogen can help the sewage plant understand the treatment effect and ensure that the effluent meets national and local discharge standards. During the treatment process, monitoring the value of ammonia nitrogen can help the sewage plant understand the effect of each link in the treatment process and adjust the treatment plan in time. The DUC2-NH online ammonia controller developed and produced by daruifuno has 2 SPST relays, which can be connected to the control equipment to adjust the ammonia nitrogen value in the water. The NH351 online ammonia sensor used in conjunction with the controller adopts the ion selection method and the measuring range is 0~1000mg/L.
