What is Dichloramine?

Monitoring cyanuric acid levels in water, particularly in swimming pools and spas, is crucial for maintaining a healthy and safe aquatic environment. Cyanuric acid, often referred to as a stabiliser or conditioner, plays a pivotal role in protecting chlorine from rapid decomposition under the sun’s ultraviolet (UV) rays. This protection is essential because chlorine serves as the primary disinfectant in pools, eliminating harmful pathogens and preventing algae growth. However, maintaining the correct balance of cyanuric acid is key; too low levels can result in chlorine degrading too quickly, while excessively high concentrations can diminish chlorine’s effectiveness as a disinfectant. Industry guidelines suggest keeping cyanuric acid levels within the range of 30 to 50 parts per million (ppm) for optimal efficacy.


Monitoring Dichloramine in Water

Monitoring dichloramine levels in water is an essential practice within the context of drinking water treatment and disinfection. Dichloramine, a form of chloramine, is formed when ammonia is added to chlorine-treated water, leading to a mixture of monochloramine, dichloramine, and trichloramine under certain conditions. The presence of dichloramine, while effective in maintaining residual disinfection over long distances in water distribution systems, requires careful management due to its potential health impacts and its role in the taste and odour issues in drinking water. Additionally, understanding the dynamics of chloramination, including the ratio of chlorine to ammonia, is vital as it influences the formation of different chloramine species. Effective monitoring strategies involve not only assessing chloramine residuals but also tracking free ammonia, nitrate/nitrite levels, and heterotrophic bacteria plate counts. This comprehensive approach ensures that water utilities can manage disinfection processes efficiently, mitigate nitrification risks, and ultimately provide safe, high-quality drinking water to the public.
