requirements. Therefore, if ammonia is added first, a means of ensuring that CT requirements are met must be developed.
To ensure that these compounds are not formed, common practice was to limit the chlorine to ammonia ratio to 3:1. However, because of problems such as nitrification and biofilm growth, which can be caused by excess ammonia, current practice is to use a Cl2:N ratio in the range
of 3:1 to 5:1, with a typical value of 4:1.
