Liquid Chlorine Gas
Cas No. 7782-50-5
CHLORINE GAS is a disinfectant and oxidant used in a wide variety of
markets including municipal drinking water and wastewater treatment, pulp &
paper processing, industrial cooling and process water treatment,
agricultural, and food and beverage processing.
Disinfection
Sanitation and disinfection in drinking water plants, food and beverage
preparation equipment and facilities, and the disinfection of contact
surfaces in medical facilities are required to prevent the spread of
infectious diseases and control the growth of microorganisms.
Disinfection is the process of inactivating through killing, or otherwise
rendering nonviable or nonvirulent, a large proportion of waterborne
microorganisms, such as fecal and other pathogenic bacteria, viruses, and
coccidian cysts. Sanitation relates to the cleanliness of surfaces and
equipment.
Food & Beverage Industry
Sanitation and disinfection is a critical process in the production of food
and beverages. Applications include treatment of water used for washing and
sanitizing raw materials, processing equipment, plant facility and ancillary
equipment and treatment of process water used for cooking or added directly
to the product, bottle rinsing and can conditioning.
Drinking Water
Disinfection of drinking water has been a major factor in reducing epidemics
of typhoid and cholera which were common throughout American Cities one
hundred years ago.
Disinfection is achieved by the addition of chemicals effective at
controlling the pathogenic microorganisms that cause health problems in
humans.
Under US National Primary Drinking Water Regulations, the disinfection
treatment must be sufficient to ensure at least a 99.9 percent (3-log)
removal and/or inactivation of Giardia lamblia cysts and 99.99 percent
(4-log) removal and/or inactivation of enteric viruses The most common
disinfectant used in drinking water is chlorine.
Chlorine is used as both a primary and secondary disinfectant. The
publication of the Stage 1 DBPR has lead to the use of alternate
disinfectants where the potential for thrihalomethane (THM) and haloacetic
acides (HAA5) formation is likely to exceed the MCL and MCLG limits set by
the USEPA. Alternative approved disinfectants that reduce the level of DBP
include chlorine dioxide and UV.
