The Hach Nitrification Monitoring Test Kit helps drinking water utilities monitor nitrification in chloraminated distribution systems by measuring free ammonia, monochloramine, nitrite, and chlorine residuals using a portable DR900 colorimeter.
Nitrification Control Test Kit Monitor early signs of nitrification in chloraminated drinking water systems before disinfectant residual loss impacts water quality compliance.
Key Values • Portable field-ready testing with DR900 Colorimeter • Detect nitrification risk earlier • Monitor free ammonia, monochloramine, nitrite, and chlorine residuals • Designed for chloraminated distribution systems • Support regulatory compliance and water quality stability
Applications The Hach Nitrification Control Test Kit is designed for: • Municipal drinking water utilities using chloramination • Distribution system nitrification monitoring programs • Water quality troubleshooting • Chloramine residual management • Legionella and Naegleria fowleri risk reduction initiatives • Free ammonia and nitrite monitoring
Why Monitor Nitrification?
Nitrification is a biological process that can occur in chloraminated drinking water systems when ammonia-oxidizing bacteria convert ammonia into nitrite and nitrate. As nitrification progresses, utilities may experience:
• Loss of disinfectant residual • Increased nitrite levels • Elevated bacterial growth • Taste and odor complaints • Corrosion risk from lower pH • Increased risk of total coliform detection • Distribution system instability
Routine monitoring of free ammonia, monochloramine, nitrite, and chlorine residuals helps operators identify nitrification conditions before they impact compliance or water quality.
Who Uses This Test Kit? • Municipal drinking water utilities • Distribution system operators • Water quality laboratories • Environmental compliance teams • Public health agencies
Used for the routine monitoring of water quality parameters that contribute to or indicate nitrification is occurring in chloraminated water systems
Versatile kit contains the DR 900 Colorimeter and reagents to perform tests for Free Ammonia, Monochloramine, Nitrite, Total Chlorine (low range and high range)
