What Is Sewage Treatment Plants And How They Work
?

• It is one of the sewage treatment plant methods
  designed to store contaminated water in specially
  designed compartments. The plant goes through the
  steps of extracting waste from the wastewater
  inflow.

Sewage/Wastewater Is Processed In Several Stages

• 1. Preliminary Treatment
• 2. Primary Treatment
• 3. Secondary Treatment
• 4. Tertiary Treatment

1. Preliminary Treatment

• Preliminary processing operations usually involve
  large filtering screens, sand removal and, in
  some cases, breakage of large objects. Excessive
  grit can cause severe pump blockage, affecting
  the subsequent treatment pump range.

2. Primary Treatment
The main purpose of this sewage treatment plant
is to reduce organic and inorganic solids that
settle on the floor by sedimentation while oil,
grease and lighter solids float on the surface
with skimming. The precipitated and suspended
material removed and the remaining liquid is
discharged or subjected to the next step.

3. Secondary Treatment
This is also known as biological sewage treatment
and is accomplished through spraying and
activated sludge methods. In the sprinkler
filter, water is sprayed with bricks in an
enclosed space. This brick is covered with a
microbial layer that oxidizes all impure
substances. The activated sludge process involves
adding microorganisms to sewage and aeration.

4. Tertiary Treatment
The tertiary treatment generally follows the
secondary treatment and helps to remove the
wastewater component that can not be removed in
the secondary treatment. Treated wastewater is
sometimes disinfected chemically or physically
before being released into the receiving
environment.

Conclusion

• Wastewater has a high BOD, reflective and total
  dissolved solids. Our goal is to make this water
  safe to be disposed of in the natural environment
  or used for other purposes
