3.  Sewage treatment plants (STPs) are specialized buildings
created to treat wastewater from residential, commercial, and
industrial sources, often known as sewage or effluent.
 Their primary duty is to clean wastewater of toxins and
pollutants so that it is suitable for reuse or disposal.
 Sewage treatment facilities are essential for upholding public
health, safeguarding the environment, and conserving water
supplies.
WHAT ARE SEWAGE TREATMENT PLANT

4. Importance of Sewage Treatment Plants:
 Environmental Protection
Organic materials, bacteria, toxins, and minerals found in sewage are toxic and
can affect ecosystems and aquatic life if released into the environment
unchecked. By shielding rivers, lakes, and seas from contamination and
preserving biodiversity, STPs aid in the prevention of water pollution.
 Public Health Safeguarding
Eliminating disease-causing bacteria from sewage through proper treatment
stops the spread of waterborne illnesses and protects the general public’s
health. STPs improve community health by removing dangerous bacteria,
viruses, and parasites and lowering the possibility of epidemics.
 Resource Conservation
Sewage treatment plants will recover water and other important resources
and make them available again. To reduce the strain on freshwater
supplies and promote sustainable water management. We will utilize
treated wastewater for industrial processes, irrigation, or groundwater
replenishment.

5. Components and Processes Involved:
 Collection and Conveyance
A system of underground pipes collects and transports sewage from homes,
businesses, and industries to the treatment facility.
 Preliminary Treatment:
The sewage is first treated as it arrives at the STP, including screening to get
rid of large debris and grit removal to get rid of sand, gravel, and other coarse
materials.
 Primary Treatment:
Wastewater is first processed in huge tanks where solids collect as sludge on
the bottom. It will leave clean and clear water. Primary effluent, or partially
treated water, advances to the following stage of treatment.

6.  Secondary Treatment:
Secondary treatment removes dissolved organic matter and nutrients from
wastewater using biological methods. Aeration tanks contain microorganisms,
such as bacteria and protozoa, that break down organic compounds. Activated
sludge also creates secondary effluent in addition to primary effluent.
 Tertiary Treatment:
You can raise the quality of effluent by using a tertiary treatment stage. Use
modern oxidation techniques, filtration, and disinfection to make sure the
water is safe for reuse and disposal.
 Sludge Treatment:
The primary and secondary treatment sludge will undergo additional processing
to decrease its volume and stabilize its organic composition. Anaerobic
digestion, dewatering, and drying are typical sludge treatment techniques. The
sludge will either convert into fertilizer or will utilize to make power.
