This is a method of treatment which has been employed for many purposes in all stages in wastewater treatment, and even prior to preliminary treatment. It involves the application of chlorine to the wastewater for the following purposes:
1. Disinfection or destruction of pathogenic organisms
2. Prevention of wastewater decomposition --
(a) odor control, and
(b) protection of plant structures
1. Aid in plant operation
(a) Sedimentation,
(b) trickling filters,
(c) activated sludge bulking
1. Reduction or delay of biochemical oxygen demand (BOD)
While chlorination has been commonly used over the years, especially for disinfection, other methods to achieve disinfection as well as to achieve similar treatment ends are also used. Among the most common is the use of ozone. In view of the toxicity of chlorine and chlorinated compounds for fish as well as other living forms, ozonation may be more commonly used in the future. This process will be more fully discussed in the section on disinfection.
