  • Chlorination of waste water is the application of chlorine to a wastewater to accomplish some definite purpose.  
  • The purpose of chlorination may not always be disinfection and may, in fact, involve odor control or some other objective which will be noted.
  • Chlorine may be applied in two general ways, gaseous and liquid. 
  • In general, the effective chemical form of chlorine that either destroys the microbe or acts against odor, etc., is the same.  
  • Gaseous forms of chlorine are generally first dissolved in water prior to addition to the waste water stream, while liquid forms of chlorine (called hypochlorites) are sold in the form of water soluble salts.
