This article discusses several methods useful in overcoming the NCl 3 problem. These include aeration, activated carbon filtration, dechlorination by S0 2 in conjunction with the use of NH 3 and Cl 2 to produce a final chlorine‐ammonia residual, and dechlorination of HOCl by NH 3 , with the attendant procedure of adjusting the final chlorine‐ammonia residual. The degree of success and usefulness of these procedures will vary considerably, depending on the type of water treatment plant, raw‐water conditions and level of free‐residual chlorination being applied.
