Disinfection of Drinking Water
The goal of water disinfection is the inactivation of microorganisms, such as viruses, bacteria and protozoa, which can cause serious illnesses and death. Although disinfection can be accomplished to a significant extent by a number of physiochemical water treatment processes, such as coagulation, sedimentation, filtration, lime-soda softening and adsorption, a specific chemical disinfection step is usually incorporated into surface water treatment process trains to prevent the transmission of waterborne diseases.

Alternative Technologies – Chlorine Dioxide
First used in beginning of 20th century, Ostend Belgium.
Known powerful water disinfectant, implemented to water disinfection in 1950’s.
Approximately 700-900 installations in water treatment.
Does not react with organics in the same way chlorine does.

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.

Lecture 3: 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.

Section 5.4 Disinfection with Chlorine Dioxide
1. Characters of chlorine dioxide
• ClO2 is a yellowish‐green gas with acrid odor under room temperature.
• Extremely unstable, both gas and liquid chlorine dioxide are explosive. Thus it should be prepared on site and used as aqueous solution.
• Soluble in water with a solubility 5 times of the chlorine’s; and It exists in water as dissolved gas, without any hydrolysis.
