The source of ammonia nitrogen in water includes three aspects: nitrogenous organic matter produces ammonia ammonia under the decomposition of microorganisms; Ammonia and nitrite can be converted into each other; Certain industrial wastewater, such as coking wastewater and synthetic ammonia fertilizer wastewater. Ammonia ammonia exists in water in the form of free ammonia or ammonium salts, and the composition ratio of the two depends on the pH value and water temperature of the water, and when the pH value is high, the proportion of free ammonia is higher. Conversely, the proportion of ammonium salt is high, and the water temperature is the opposite.
Ammonia nitrogen also has a significant impact on the ecological environment, ammonia nitrogen on aquatic organisms harmful mainly free ammonia, its toxicity is dozens of times greater than ammonium salt, and with the enhancement of alkalinity and increase. Ammonia nitrogen toxicity is closely related to the pH value and water temperature of the pool water, in general, the higher the pH value and water temperature, the stronger the toxicity, and the harm to fish is similar to nitrite. Fish are sensitive to ammonia nitrogen in water, and high levels of ammonia nitrogen can lead to fish death. The determination of ammonia nitrogen in water helps to evaluate the pollution and "self-purification" of water bodies.
The NH351 ion electrode ammonia sensor (NH4-N) launched by Delfino is green and pollution-free, and can be monitored online in real time. Integrated ammonium, potassium, pH and reference electrodes automatically compensate for potassium, pH and temperature in the water. The ammonia sensor can be directly immersed in installation, which is more economical and environmentally friendly, convenient and fast than the traditional ammonia nitrogen analyzer. The sensor comes with a self-cleaning brush that prevents microorganisms from attaching, resulting in longer maintenance intervals and reliability. Using RS485 input, the ammonia analyzer supports Modbus, easy to integrate.
