Automation and advanced technologies reduce the manual effort required for sewage treatment. It increases efficiency and allows for more effective resource allocation.

Fertilizer production: STP can produce nutrient-rich biosolids suitable for use as fertilizers. Recycling organic matter from wastewater into fertilizers promotes agricultural sustainability.

Energy production: Some sewage treatment processes generate biogas, a renewable energy source. Harnessing energy from wTypical Raw Sewage Analysis:

Sr. No Parameter Unit Average

1. pH - 5.5-8.0

2. TSS Mg/l 150- 200

3. BOD Mg/l 200-250

4. COD Mg/l 500-600

5. Oil & Grease Mg/l < 25

Typical Treated Sewage Analysis: After Tertiary Treatment:

Sr. No Parameter Unit Treated water as per PCB

1 pH - 6.5 - 8.5

2 TSS Mg/l < 30 - 10

3 BOD Mg/l < 10- 30

4 COD Mg/l < 50 -100

5 Oil &Grease Mg/l < astewater helps in sustainable power production.

STP water refers to water that has been treated at a sewage treatment plant (STP) to remove contaminants and make it safe for reuSewage Treatment Plant (STP)

Sewage treatment is a wastewater treatment process to remove contaminants from wastewater to produce an effluent that is suitable for discharge to the surrounding environment or it can be reuse in various application, thereby preventing water pollution from raw sewage discharges.

Sewage treatment can be done in three phases:

1) Preliminary (screening & grit removal) for removal of some bulky solids like paper, plastics, sand etc,

2) Primary (Sedimentation) for removal of some light organic matter, and

3) Secondary (SBT Filtration) for Bacterial decomposition.se or release into the environment:
