What is a Sewage Treatment Plant?
A Sewage Treatment Plant (STP) is a facility that removes contaminants from wastewater (sewage) from homes and industries, converting it into reusable water or safe effluent for environmental discharge. Using physical, biological, and chemical processes, STPs treat sewage in stages—screening, sedimentation, aeration, and disinfection—to protect public health, prevent pollution, and conserve water.
Treatment Process Stages
Our STPs employ a comprehensive multi-stage treatment process:
- Primary Treatment: Initial screening and sedimentation to remove large solids and suspended particles
- Secondary Treatment: Biological processes using microorganisms to break down organic matter
- Tertiary Treatment: Advanced filtration and disinfection to produce high-quality treated water
Our STP Technologies
We offer multiple advanced technologies to suit different requirements:
Modular STP - Advanced MBBR
State-of-the-art modular sewage treatment plants using advanced Moving Bed Biofilm Reactor technology. These systems offer superior performance in a compact footprint with minimal maintenance requirements.
SBR - Sequencing Batch Reactor
An advanced activated sludge process that treats wastewater in batches within a single reactor tank. It combines aeration, clarification, and sludge settling into a single-tank process, making it compact, efficient for fluctuating loads, and ideal for treating municipal or industrial sewage.
MBBR - Moving Bed Biofilm Reactor
Uses floating plastic carriers (media) in aeration tanks to support high-density microbial growth (biofilm). It enhances nutrient removal (BOD, COD, Nitrogen) by combining activated sludge with fixed-film, offering a compact, efficient, and low-maintenance solution.
MBR - Membrane Bioreactor
Combines conventional biological treatment (activated sludge) with membrane filtration (ultrafiltration or microfiltration). It replaces secondary clarifiers with membrane modules, resulting in a compact, highly efficient system that produces exceptional, pathogen-free water suitable for reuse.
Treatment Process Technologies
ASP - Activated Sludge Process
A widely used, effective biological wastewater treatment technology that uses microorganisms and aeration to break down organic matter. It involves aerating sewage to stimulate bacteria, which digest pollutants, followed by settling in a secondary clarifier and sludge recirculation.
