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.

Biocides for Disinfection and Storage of Hydranautics Membrane Elements
This bulletin provides general information about biocides that may be used with Hydranautics membrane elements for disinfection and/or storage. Before storage or disinfection of Hydranautics elements, one should become familiar with Technical Service Bulletins 108 and 118 which describe the general storage and flushing procedures for all Composite Polyamide, and PVD membrane elements. Also, one should confirm which type of membrane elements are actually in the system. Since elements may be composed of either composite polyamide membrane or polyvinyl derivative, it is imperative to be certain of the type to be disinfected.

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 Oxidation
Disinfection:
is killing or inactivate of pathogenic organisms. It is necessary if the water to be used for drinking water is not hygienically reliable. In water treatment, aimed at the production of drinking water, disinfection is the most important treatment step. Purpose of disinfection: To make Drinking water free of any disease causing bacteria and microbes.

Disinfection Basics
Disinfection Basics CEU Training Course This course will cover the fundamentals of water disinfection beginning with the different and alternative water disinfectants and ending with the biological analysis of the water, insuring that the water meets federal compliance. Task Analysis and Training Needs Assessments have been conducted to determine or set Needs-To-Know for this course. The goal of this CEU Course is to provide awareness training to help workers recognize the occupational hazards and health effects of different disinfectants, halogens, chlorine exposure and the exposure controls; and to familiarize the participants with the properties and safe handling of chlorine - solid, liquid, gas, and the operation of gas chlorinators and other related equipment.

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.

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.
