Disinfection Of Treated Wastewater
These guidelines provide a framework of best practices for the disinfection of treated wastewater destined either for reuse or disposal to surface waters. They will also assist water businesses and private owners of package sewage treatment plants to meet their obligations for environmental protection as stated in the SEPP (Waters of Victoria). The ultimate goal of wastewater treatment and disinfection is to produce an effluent of such quality (dependent upon final use) that minimal additional controls are needed to manage any human health, agricultural or environmental risks.

Chlorination: Disinfection And Oxidation
• Disease causing organisms can be found in surface water and some in ground water, some can be removed by preliminary, primary and secondary treatments processes. But not all are removed.
• The addition of a chemical disinfectant is necessary if a water treatment processes is to meet the coliform MCL, preventing any water borne diseases.
• Cl2, due to it relatively low cost & ease with which it be obtained is the most commonly used chemical for this purpose.
• Chlorine is available in 3 forms:
1. Chlorine Gas
2. Calcium or Sodium Hypochlorite solution
3. Calcium or Sodium Hypochlorite powder (HTH)

Disinfection and Chlorination
Disinfection is the process designed to kill or inactivate most microorganisms in wastewater, including essentially all pathogenic organisms. Contrast this to sterilization, which is the removal and destruction of all living microorganisms, including pathogenic and saprophytic bacteria, vegetative forms and spores.

Evaluation of Chlorine Dioxide (ClO2) Generation System for Disinfection in RO Product Water at SWCC Jubail Plant
Recent studies have shown the formation of bromate in desalination-derived drinking water, especially when the desalinated water is treated with sodium
hypochlorite solution produced by electrolyzing seawater.

Disinfection Practices for Water – Basic
. Chemical and physical relationships govern all disinfection chemistry
. Knowledge of these relationships increases operator skills and troubleshooting abilities
. Allows operators to control conditions that optimize disinfection practices
. Treatment processes are managed to disinfect water for consumption and to meet regulatory objectives
. Minimum disinfectant residuals
. CT compliance - demonstration of efficient disinfection
