Question
Chapter 22.8, Problem 1MQ
Summary Introduction
Water released from wastewater treatment plant is not safe for human consumption. It can only be released in water bodies. To make water potable, further treatment steps are required which involve sedimentation, coagulation, filtration, and disinfection. All these step help in removal of harmful pathogens, elements from the water and improves its taste and odor.

Students have asked these similar questions
a)
Define 'Disinfection' and 'Sterilization' OR differentiate between them.
b)
Enlist the different methods of 'Disinfection' which method would you recommend for 'Municipal Water Supply' and WHY? Depending on the
availability of 'Source of Water which 'Source' is more important than the other for disinfection and WHY? Give reason.
c)
of them is stronger than the other and by what percentage?
Define or differentiate between “Free Available Chlorine" and “Combined Available Chlorine". Write their Chemical Formulae and mention which one
d)
Define “Break Point Chlorination". With the help of a neat Figure' show the "Break Point" and also show "Combined Available Chlorine", "Free
Available Chlorine" and "Total Available Chlorine". Mention the “Dosage" in order to obtain a “Free Available Chlorine Residual" of about 0.5 mg/l or
above.
e)
Define the term “Chlorine Demand" of water. What are the "Factors" OR enlist the "Factors" that show the "Effectiveness of
Chlorine".
What general procedures are used to reduce microbial numbers(microbial load) in water supplies?
Can you describe a situation where high-level disinfection
would be needed? Medium-level? Low-level?
