monochloramine has been used. A drop in monochloramine would be an indication that the free ammonia level has likely increased, which may indicate the onset of nitrification, and the situation may be out of compliance

value is used when the treated water is to be blended with a surface water which contains high levels of organic matter or contains ammonia. The chlorine will likely be consumed by the chlorine demand of the

, and support.   Explore the various parameters and methods for surface water monitoring below.     Ammonia Ammonia levels can reach mg/L in surface water, especially in smaller water bodies and streams located

.   Explore the various parameters and methods for source water monitoring below.   Ammonia Ammonia levels can reach several mg/L in groundwater systems, especially those located in agricultural areas. The ammonia levels can change seasonally and need to be monitored. The ammonia will react with chlorine to form chloramines, creating an uncontrolled

Chloramination   Is Chloramination right for you?  Chloramination disinfects drinking water by adding chlorine and ammonia to achieve a residual of monochloramine. Chloramination is favored for disinfection

). Because plants cannot use gaseous nitrogen, they rely on nitrogen fixing bacteria in the soil to convert it to ammonia and nitrite . Nitrate-forming bacteria convert nitrite into nitrate under aerobic

(OCl – ) ion or bleach, and is commonly added to water systems for disinfection. When ammonia or organic nitrogen is also present, chloramines known as monochloramine, dichloramine, and trichloramine will

Chloramination How to determine the LAS feed rate based on chlorine feed rate and the measurement of ammonia levels. UV Methods for DBP Control and UV Disinfection Discusses the difference between the UV/254 Transmission

represents a more oxidized state of nitrogen. Autotrophic bacteria convert ammonia into nitrite and then into nitrate under aerobic conditions; lightning converts large amounts of atmospheric nitrogen (N 2 ) directly

monochloramine by difference (not recommended). The better solution is to monitor monochloramine and free ammonia to optimize the chloramination process, to keep free ammonia to a minimum, and prevent nitrification in the distribution systems. Distribution Lines — In distribution

article focuses on how to determine the LAS feed rate based on chlorine feed rate and the measurement of ammonia levels. Proper Measurement is the Key to Proper Control. Measure total ammonia with a test kit or lab method, for example the salicylate method, to detect/control the
