Activated Sludge Wastewater Treatment
How
Does Activated Sludge Wastewater Treatment Work?
Written
by AOS Treatment Solutions
The activated sludge wastewater treatment
process is widely used and relied on by many municipalities.
Oxygen is used to establish and regulate
aerobic conditions and to suspend the sludge.
The activated sludge wastewater treatment
provides many advantages, but it may not be appropriate in all situations.
WHAT
IS ACTIVATED SLUDGE WASTEWATER TREATMENT?
Air or oxygen is blown into raw sewage. It
is most effective for large volumes of water.
Wastewater is mixed and aerated in a
special tank. This step in the process occurs by pumping air or oxygen into the
activated sludge tank or using surface aerators.
The process oxidizes organic matters in the
wastewater, producing new cells, carbon dioxide, and water.
The sludge particles can then be removed
through the process of gravity settling.
Activated sludge sewage treatment is
ideally completed in a centralized treatment facility.
The treatment of activated sludge can occur
in most climates. However, colder environments reduce the treatment capacity.
AOS professionals can discuss activated
sludge treatment methods and other wastewater treatment services during a
thorough consultation.
HOW
DOES THE ACTIVATED SLUDGE PROCESS WORK?
This process smashes the solids. The sewage
is bubbled, and sewage liquor is discharged into an activated sludge chamber.
Live bacteria settle to the bottom of the
tank and dead bacteria float to the top.
Clean water is discharged into a soakaway
or watercourse while the live bacteria return to the digestion chamber.
It is important to understand what
activated sludge is to comprehend how the complete activated sludge system
works.
The sludge is considered activated because
the particles are actively swarming with beneficial bacteria that digest the
sewage.
ADVANTAGES
OF THE ACTIVATED SLUDGE TREATMENT PROCESS
Sewage treatment plants that primarily use
the process for the treatment of activated sludge offer the following
advantages:
o
The
amount of undesired sludge is reduced.
o
The
sewage treatment plants re-seed themselves with beneficial bacteria.
o
The
activated sludge treatment process allows the emptying intervals to be longer.
o
The
process is very reliable.
o
The
process is more simple.
o
Costs
are reduced.
o
The
process can be odorless.
The activated sludge treatment process is
one of the water treatment services that AOS has provided for decades. Our
professionals can discuss if this method is appropriate, as well as other
services that we provide.
DISADVANTAGES
OF THE ACTIVATED SLUDGE TREATMENT PROCESS
The activated sludge treatment process does
have some drawbacks and may not be appropriate for all applications.
Some disadvantages associated with
activated sludge include:
o
There
are initial high capital and operating costs that may deter some facilities
from utilizing this method.
o
Experts
are required to design and construct the activated sludge system.
o
Skilled
personnel must operate and maintain the treatment of activated sludge.
o
Electricity
must be continuously used, increasing wastewater treatment energy consumption.
o
Parts
and materials may not be available on a local level.
o
Sludge
and effluent might require further treatment or appropriate discharge.
The activated sludge treatment process can
provide an effective method to treat wastewater.
