Water Purification Exam Questions and
Answers 100% Solved
Water - ✔✔The most important potential common source of infectious
disease (i.e., Cholera, Shigellosis, Typhoid fever, etc); Can also be a
source for chemically induced intoxications
Public health - ✔✔Ensuring water purity is essential for _______
Microorganisms - ✔✔Treatment and purification schemes use _____ to
identify, remove and degrade pollutants
Wastewater - ✔✔Domestic sewage or liquid industrial waste
Wastewater treatment - ✔✔Relies on industrial scale use of microbes for
bioconversion; Following treatment, the effluent waters suitable for release
into surface waters, release to drinking water purification facilities, NOT for
drinking water.
Effluent water - ✔✔Discharged treated wastewater
Sewage- Wastewater treatment - ✔✔Consists of a number of steps that are
spatial separated; Its goal is to reduce organic and inorganic material in

wastewater to a level that no longer supports microbial growth and to
eliminate other potentially toxic materials; Has lead to major reduction in
spread of pathogens.
Primary Treatment - ✔✔Physical step in the wastewater treatment process;
Removes solid material and form of sludge. Uses physical separation
methods to separate solid and particulate organic and inorganic materials
from wastewater (screening and sedimentation)
Secondary Treatment - ✔✔Biological step in wastewater treatment
process. Dissolved organic matter transformed into microbial biomass and
carbon dioxide by aerobic respiration and fermentative reactions carried out
by various microbes; Forms stable floc-settles well, bulking sludge-does not
settle properly
Activated sludge system - ✔✔Horizontal flow or materials with recycling of
sludge; Part of secondary treatment.
Tricking filter - ✔✔Waste effluent passed over rocks/solid materials with
microbial biofilms; the community degrades the organic waste.
Extended Aeration - ✔✔Reduces the amount of sludge produced by using
microbial biomass for energy requirements.
