Disinfection
• 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.

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.

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.

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.
