Scrubbers For Air
Pollution Control
water@watermanaustralia.com

Before they are released
into the atmosphere,
industrial exhaust gases are
cleaned by scrubbers, which
are air pollution control
systems.
They are frequently
employed in industrial
operations that release
gases including sulphur
dioxide, nitrogen oxides, and
particulate matter, all of
which are dangerous to the
environment and to people's
health.
The most common kind of
scrubbers are known as wet
scrubbers, and they function
by spraying a liquid solution
over the exhaust gas stream,
which subsequently traps
and removes the pollutants
from the gas.

Scrubbers can be successful at removing pollutants from industrial exhaust gases,
but doing so can produce trash that needs to be disposed of correctly. Scrubbers
also require energy to run.
Scrubbers are utilised in many different industries, including as metal processing,
chemical manufacture, and power generating etc.. They can aid in lowering
emissions of pollutants including particulate matter and sulfur dioxide, which can
both contribute to acid rain and cause respiratory issues.

Scrubbers are a crucial
instrument in the fight
against air pollution, but to
ensure that emissions are
reduced to the absolute
minimum.
they should be used in
conjunction with other
strategies like pollution
prevention and source
reduction.

1. Flue Gas Desulfurization
(FGD) Scrubber, Desulfurization
of Flue Gas Equipment's

The solution reacts with the sulfur dioxide in the gas stream, forming a solid compound that
can be collected and disposed of.
The FGD process involves spraying a liquid solution, usually a mixture of water and limestone or
lime, into the flue gas stream.
Sulfur dioxide is a hazardous gas produced by the combustion of fossil fuels such as coal and oil,
and it contributes to acid rain and other environmental issues.
FGD, commonly known as a wet scrubber, is a form of air pollution management device used to
remove sulphur dioxide (SO2) from industrial process and power plant exhaust flue gases.

The FGD equipment typically consists of a scrubbing tower or vessel, a recirculation system for the
liquid solution, and a solid handling system for the by-products.

There are several types of
FGD systems, including
spray tower, venturi scrubber, and
packed bed scrubber
systems.
Each system has its own
unique advantages and
disadvantages, depending
on the specific application
and operating conditions.

One of the main advantages of
FGD equipment is its
effectiveness in removing sulfur
dioxide from flue gas streams.
With proper design and
operation, FGD systems can
remove up to 99% of the sulfur
dioxide emissions from power
plants and industrial processes.
This can significantly reduce the
environmental impact of these
operations and help to meet
regulatory requirements.

water@watermanaustralia.com This can provide a cost
savings and
environmental benefit
for the facility.
The solid compounds
formed during the FGD
process, such as gypsum
and calcium sulfite, can
be sold or reused in
other applications, such
as cement
manufacturing and
agriculture.

Packed Tower Gas
Scrubber:

• Tower Gas in Packing In scrubbers, a tower of
packing material is used to increase the surface
area of the gas-liquid contact region.
• As the gas stream moves through the tower, the
liquid stream that removes contaminants interacts
with it.
• By entering the tower through the intake near the
bottom and moving through the support plate and
packed bed in the opposite direction as the
scrubbing liquid flow, gas eliminates
contaminants.
• After passing through the packed bed, the cleaned
gas continues its journey towards the top of the
tower through a mist eliminator section. In this
case, any entrained liquid is removed before the
pure air is released through the exit.
• These types of scrubbers work best when the gases
being handled are clear of particles, as these have
a tendency to clog the packing.

Advantages:
• Packed Tower Gas Scrubbers are effective
at removing a wide range of pollutants,
including particulate matter, acid gases, and
organic compounds.
• Application: Packed Tower Gas Scrubbers
are commonly used in industries such as
chemical manufacturing, pharmaceuticals,
and wastewater treatment

systems that combine several
different air pollution control
technologies into a single unit.

Advantages: Packaged Scrubbers
are compact and easy to install
and can be used to control a wide
range of air pollutants. They are
particularly effective at removing
particulate matter and acid gases.
Application: Industries like food
processing, pharmaceuticals,
wastewater treatment, and
water-soluble VOC cleaning all
frequently employ packaged
scrubbers to remove chlorine,
HCI, ammonia, and SO2 or H2S.

3. WET Electrostatic
Precipitators:

An electrostatic precipitator known as a WET Electrostatic Precipitator (ESP) removes
contaminants from gas streams by using a liquid medium.
A high voltage electrode is used to charge the pollutants in the gas stream, which attracts them to
the liquid medium.
In an ESP chamber, contaminated air is drawn in and ionised by electron emitting electrodes.
The electron field charges the suspended particles, which then move to a collection plate.
Rapping or beating the collection plates with rappers periodically removes accumulated particle
matter from the plates.
Heavy particles fall to the ESP's base where they are collected in hoppers for disposal.

Advantages:
• WET ESPs are effective at removing a wide
range of pollutants, including fine particulate
matter and acid gases. They are also
relatively easy to operate and maintain.
• Application: WET ESPs are commonly
used in industries such as power generation,
cement manufacturing, and metal
processing.

vapours, and mists. Because there is so much
contact between the gas and the liquid because of
the turbulence, pollutants can be removed
effectively.
