STP (Sewage Treatment Plant)

A Sewage Treatment Plant (STP) is designed to treat domestic and commercial wastewater to make it safe for discharge or reuse. At Allied Enviro Engineering, we specialize in designing, installing, repairing, and maintaining high-performance STP systems across India at competitive prices.

Our expert engineers ensure efficient wastewater treatment that supports environmental sustainability and regulatory compliance.

What is a Sewage Treatment Plant?

Sewage Treatment is the process of removing contaminants from wastewater generated by:

• Residential buildings

• Commercial establishments

• Industries

• Rainwater runoff

The goal of an STP is to produce environmentally safe treated water that can be discharged into water bodies or reused for gardening, flushing, or industrial purposes.

Importance of STP System

✔ Protects the environment from pollution
✔ Prevents contamination of water bodies
✔ Promotes water reuse and recycling
✔ Ensures compliance with pollution control norms
✔ Reduces health risks

Technologies Used in Sewage Treatment Plant

At Allied Enviro Engineering, we provide advanced STP technologies based on project requirements, space availability, and wastewater characteristics.

1. MBBR (Moving Bed Biofilm Reactor)

MBBR technology uses thousands of biofilm carriers suspended in an aeration tank. These carriers provide a large surface area for bacterial growth.

Key Features:

• High treatment efficiency

• Compact design

• Low maintenance

• Automatically adapts to load fluctuations

• Cost-effective operation

MBBR is widely used for municipal and industrial wastewater treatment.

2. MBR (Membrane Bio-Reactor)

MBR combines biological treatment with membrane filtration (Microfiltration or Ultrafiltration). It replaces conventional secondary clarifiers used in Activated Sludge Process (ASP).

Advantages of MBR:

• Superior treated water quality

• Smaller footprint

• Efficient solid-liquid separation

• Reduced sludge production

• Ideal for water reuse applications

MBR is suitable for both municipal and industrial wastewater treatment projects.

3. SBR (Sequencing Batch Reactor)

SBR technology treats wastewater in batches through controlled aeration and settling cycles.

Working Process:

1. Wastewater enters primary chamber.

2. Biological treatment occurs in SBR tank.

3. Aeration and settling phases alternate.

4. Treated water is discharged.

5. Sludge is recycled for further treatment.

Benefits:

• High treatment efficiency

• Flexible operation

• Compact system

• Suitable for small to medium-scale projects

4. SAF (Submerged Aerated Filter)

SAF is an up-flow biological treatment system using plastic media that supports bacterial growth.

Key Features:

• Continuous oxygen supply via air blowers

• Efficient mixing of wastewater

• High microbial activity

• Durable and low maintenance

SAF systems are suitable for both domestic and commercial wastewater treatment.

Applications of Sewage Treatment Plant

Our STP systems are widely used in:

• Residential complexes

• Hotels & hospitals

• Commercial buildings

• Industrial units
