Disinfection, Chlorination and Oxidation
Chlorination: application of chlorine to water, generally for the purpose of disinfection, but also for other purposes such as odor control.
Disinfection: the addition of chlorine, ozone, UV light, etc. to water in order to kill or inactivate disease causing organisms; effectiveness measured using the coliform test.

Disinfection
•Destruction or inactivation of pathogenic organisms
•Disinfection can be done by:– chemical means-chlorine, ozone, –non-chemical means-heat, UV irradiation

Cleaning And Disinfection Procedures For Filmtec Membrane
The following are general recommendations for cleaning FilmTec™ NF 200 and NF270 Elements. More detailed procedures for cleaning a nanofiltration (NF) system are typically included in the operating manual provided by the system supplier. It should be emphasized that frequent cleaning is not required for a properly designed and properly operated NF system, however because of the NF 200 and NF270 membrane’s unique combination of pH range and temperature resistance, cleaning may be accomplished very effectively.

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.

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.

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.
