This document discusses the health effects of air pollution and methods for controlling air pollution sources. It describes how air pollution exposure can cause both acute and chronic health effects, especially impacting the respiratory system. It then outlines several technologies used for controlling air pollutant emissions from stationary sources, including particulate control devices like cyclones and fabric filters, as well as technologies for controlling gaseous pollutants like absorption, adsorption, condensation, and incineration. The goal of these control technologies is to reduce air pollution and the associated health and environmental impacts.
Air pollution is the introduction of particulates, biological molecules, or other harmful materials into Earth's atmosphere, causing disease, death to humans, loss of breath, damage to other living organisms such as food crops, or the natural or built environment. Air pollution may come from anthropogenic or natural sources.

Often a recommendation of the external examiners and the accreditation board is the blueprinting of undergraduate examination questions. A blueprint of examination on individual assessment tool reports the students’ learning outcome. It produces a link between test items and students learning objective. It is one of the most important instruments on outcome assessment essentials that ensure the desired coverage of content and objectives at different level of training.
We can work together to keep the environment clean so the plants, animals and people who depend on it remain healthy :) Working together, we can make pollution less of a problem and make our world a better place :D :)

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

3. Human Health Effects
• Exposure to air pollution is
associated with numerous
effects on human health,
including pulmonary, cardiac,
vascular, and neurological
impairments.
• The health effects vary greatly
from person to person. High-risk
groups such as the elderly,
infants, pregnant women, and
sufferers from chronic heart and
lung diseases are more
susceptible to air pollution.
• Children are at greater risk
because they are generally more
active outdoors and their lungs
are still developing.
4. Conti…..
• Exposure to air pollution can cause both acute
(short-term) and chronic (long-term) health effects.
• Acute effects are usually immediate and often
reversible when exposure to the pollutant ends.
Some acute health effects include eye irritation,
headaches, and nausea.
• Chronic effects are usually not immediate and tend
not to be reversible when exposure to the pollutant
ends.
– Some chronic health effects include decreased
lung capacity and lung cancer resulting from long-term
exposure to toxic air pollutants.
5. Effects on Human respiratory system
• Both gaseous and particulate air
pollutants can have negative
effects on the lungs.
• Solid particles can settle on the
walls of the trachea, bronchi, and
bronchioles.
• Continuous breathing of polluted
air can slow the normal
cleansing action of the lungs and
result in more particles reaching
the lower portions of the lung.
• Damage to the lungs from air
pollution can inhibit this process
and contribute to the occurrence
of respiratory diseases such as
bronchitis, emphysema, and
cancer.

14. Source Control Technology
• Air quality management sets the tools to control
air pollutant emissions.
• Control measurements describes the equipment,
processes or actions used to reduce air pollution.
• The extent of pollution reduction varies among
technologies and measures.
• The selection of control technologies depends on
environmental, engineering, economic factors
and pollutant type.
15. Settling Chambers
• Settling chambers use the force of gravity to remove solid
particles.
• The gas stream enters a chamber where the velocity of the
gas is reduced. Large particles drop out of the gas and are
recollected in hoppers. Because settling chambers are
effective in removing only larger particles, they are used in
conjunction with a more efficient control device.
Figure: Settling chambers
16. Cyclones
• The general principle of inertia
separation is that the particulate-laden
gas is forced to change direction. As gas
changes direction, the inertia of the
particles causes them to continue in the
original direction and be separated from
the gas stream.
• The walls of the cyclone narrow toward
the bottom of the unit, allowing the
particles to be collected in a hopper.
• The cleaner air leaves the cyclone
through the top of the chamber, flowing
upward in a spiral vortex, formed within a
downward moving spiral.
• Cyclones are efficient in removing large
particles but are not as efficient with
smaller particles. For this reason, they
are used with other particulate control
devices. Figure: Cyclone Collector
17. Venturi Scrubbers
• Venturi scrubbers use a
liquid stream to remove
solid particles.
• In the venturi scrubber,
gas laden with particulate
matter passes through a
short tube with flared ends
and a constricted middle.
• This constriction causes
the gas stream to speed
up when the pressure is
increased.
Figure: Venturi scrubber components
18. Conti….
• The difference in velocity and pressure resulting
from the constriction causes the particles and water
to mix and combine.
• The reduced velocity at the expanded section of
the throat allows the droplets of water containing
the particles to drop out of the gas stream.
• Venturi scrubbers are effective in removing small
particles, with removal efficiencies of up to 99
percent.
• One drawback of this device, however, is the
production of wastewater.
19. Fabric Filters
• Fabric filters, or baghouses, remove dust from a
gas stream by passing the stream through a
porous fabric. The fabric filter is efficient at
removing fine particles and can exceed efficiencies
of 99 percent in most applications.
Figure: Fabric filter (baghouse) components
20. Conti…..
• The selection of the fiber material and fabric
construction is important to baghouse
performance.
• The fiber material from which the fabric is made
must have adequate strength characteristics at
the maximum gas temperature expected and
adequate chemical compatibility with both the
gas and the collected dust.
• One disadvantage of the fabric filter is that high-temperature
gases often have to be cooled
before contacting the filter medium.
21. Electrostatic Precipitators (ESPs)
• An ESP is a particle
control device that uses
electrical forces to move
the particles out of the
flowing gas stream and
onto collector plates.
• The ESP places electrical
charges on the particles,
causing them to be
attracted to oppositely
charged metal plates
located in the precipitator.
Figure: Electrostatic precipitator components
22. Conti….
• The particles are removed from the plates by
"rapping" and collected in a hopper located below the
unit.
• The removal efficiencies for ESPs are highly variable;
however, for very small particles alone, the removal
efficiency is about 99 percent.
• Electrostatic precipitators are not only used in utility
applications but also other industries (for other
exhaust gas particles) such as cement (dust), pulp &
paper (salt cake & lime dust), petrochemicals (sulfuric
acid mist), and steel (dust & fumes).
23. Control of gaseous pollutants from
stationary sources
• The most common method for controlling
gaseous pollutants is the addition of add-on
control devices to recover or destroy a pollutant.
• There are four commonly used control
technologies for gaseous pollutants:
– Absorption,
– Adsorption,
– Condensation, and
– Incineration (combustion)
24. Absorption
• The removal of one or more
selected components from a gas
mixture by absorption is probably
the most important operation in
the control of gaseous pollutant
emissions.
• Absorption is a process in which
a gaseous pollutant is dissolved
in a liquid.
• Water is the most commonly
used absorbent liquid.
• As the gas stream passes
through the liquid, the liquid
absorbs the gas, in much the
same way that sugar is absorbed
in a glass of water when stirred.
Typical Packed Column Diagram
25. Conti….
• Absorbers are often referred to as scrubbers, and there
are various types of absorption equipment.
• The principal types of gas absorption equipment
include spray towers, packed columns, spray
chambers, and venture scrubbers.
• In general, absorbers can achieve removal efficiencies
grater than 95 percent. One potential problem with
absorption is the generation of waste-water, which
converts an air pollution problem to a water pollution
problem.
26. Adsorption
• When a gas or vapor is brought into contact with a
solid, part of it is taken up by the solid. The molecules
that disappear from the gas either enter the inside of
the solid, or remain on the outside attached to the
surface. The former phenomenon is termed
absorption (or dissolution) and the latter adsorption.
• The most common industrial adsorbents are
activated carbon, silica gel, and alumina, because
they have enormous surface areas per unit weight.
• Activated carbon is the universal standard for
purification and removal of trace organic
contaminants from liquid and vapor streams.
27. • Carbon adsorption systems are either regenerative or non-regenerative.
– Regenerative system usually contains more than one carbon bed.
As one bed actively removes pollutants, another bed is being
regenerated for future use.
– Non-regenerative systems have thinner beds of activated carbon.
In a non-regenerative adsorber, the spent carbon is disposed of
when it becomes saturated with the pollutant.

28. Condensation
• Condensation is the process of converting a gas
or vapor to liquid. Any gas can be reduced to a
liquid by lowering its temperature and/or
increasing its pressure.
• Condensers are typically used as pretreatment
devices. They can be used ahead of absorbers,
absorbers, and incinerators to reduce the total
gas volume to be treated by more expensive
control equipment. Condensers used for pollution
control are contact condensers and surface
condensers.
29. • In a contact condenser,
the gas comes into
contact with cold liquid.
• In a surface condenser,
the gas contacts a cooled
surface in which cooled
liquid or gas is circulated,
such as the outside of the
tube.
• Removal efficiencies of
condensers typically
range from 50 percent to
more than 95 percent,
depending on design and
applications.
Contact condenser
Surface condenser
30. Incineration
• Incineration, also known as combustion, is most used
to control the emissions of organic compounds from
process industries.
• This control technique refers to the rapid oxidation of
a substance through the combination of oxygen with a
combustible material in the presence of heat.
• When combustion is complete, the gaseous stream is
converted to carbon dioxide and water vapor.
• Equipment used to control waste gases by
combustion can be divided in three categories:
– Direct combustion or flaring,
– Thermal incineration and
– Catalytic incineration.
31. Direct combustor
• Direct combustor is a device in which air and all
the combustible waste gases react at the burner.
Complete combustion must occur
instantaneously since there is no residence
chamber.
• A flare can be used to control almost any
emission stream containing volatile organic
compounds. Studies conducted by EPA have
shown that the destruction efficiency of a flare is
about 98 percent.
32. In thermal incinerators the combustible waste gases
pass over or around a burner flame into a residence
chamber where oxidation of the waste gases is
completed.
Thermal incinerators can destroy gaseous pollutants at
efficiencies of greater than 99 percent when operated
correctly.
Thermal incinerator general case
33. Catalytic incinerators are very similar to thermal
incinerators. The main difference is that after passing
through the flame area, the gases pass over a catalyst
bed.
A catalyst promotes oxidation at lower temperatures,
thereby reducing fuel costs. Destruction efficiencies
greater than 95 percent are possible using a catalytic
incinerator.
Catalytic incinerator
