Unistar Aquatech is a leading name of sewage treatment plant, we provide solutions to treat sewage effectively. When we think about a clean and healthy environment, one of the most essential systems that make it possible is a Sewage Treatment Plant (STP Plant). Every day, thousands of liters of wastewater are generated from households, industries, offices, and commercial spaces. If this wastewater is left untreated, it can pollute our rivers, lakes, and groundwater, causing severe harm to both humans and the environment.
What is an STP Plant?
A sewage treatment plant (STP Plant) is a facility designed to treat and purify wastewater before it is released back into nature or reused for various non-potable purposes. An STP plant removes contaminants, harmful bacteria, and solids from sewage water so that it becomes safe for disposal or reuse. Unistar Aquatech built using advanced technology that makes the sewage treatment plant process efficient, cost-effective, and environmentally friendly.
STP Plant Process
The STP plant process generally involves three key stages: primary, secondary, and tertiary treatment. Each stage plays an important role in cleaning the water.
- Primary Treatment: In this stage, large solid particles and refuse are removed from sewage water using screens and grit chambers. It is the first and most basic step of the sewage treatment plant process.
- Secondary Treatment: Microorganisms are used to break down organic waste present in the water. Techniques like Activated Sludge Process (ASP), Moving Bed Biofilm Reactor (MBBR), or Sequencing Batch Reactor (SBR) are used to purify water biologically.
- Tertiary Treatment: The last stage is the water is filtered and disinfected using sand filters, UV disinfection, or chlorination. After this step, the treated water becomes clear and safe for reuse or disposal.
Unistar Aquatech ensures that every STP Plant Process is designed to meet the specific needs of clients, whether it’s for residential societies, hotels, hospitals, or industries.
How Does a Sewage Treatment Plant Work?
- Collection of Sewage: Wastewater from bathrooms, kitchens, and drains is collected in the STP plant.
- Removal of Solids: Large solids like plastics, rags, and other debris are separated.
- Biological Treatment: Microbes feed on organic matter, breaking it down into simpler forms.
- Settling of Sludge: Heavier particles settle down as sludge, which is then removed.
- Filtration & Disinfection: The water is filtered and disinfected to kill harmful microorganisms.
- Recycling or Disposal: Finally, clean water is either reused or safely discharged.
The sewage treatment plant process ensures that no harmful pollutants are left in the water before it reaches the environment.
Flow Chart of Sewage Treatment Plant
A typical sewage treatment plant flow chart includes the following sequence:
Influent Sewage → Screening → Grit Chamber → Primary Clarifier → Aeration Tank → Secondary Clarifier → Filtration Unit → Disinfection (Chlorination/UV) → Treated Effluent → Disposal or Reuse
This flow chart highlights the systematic flow of wastewater through various units of treatment, ensuring that the final output is safe and meets environmental discharge standards.

Benefits of an STP Plant
There are advantages of having an efficient STP plant:
- Environmental Protection: Prevents water pollution and keeps rivers and lakes clean.
- Water Conservation: Treated water can be reused for multiple purposes.
- Compliance: Helps organizations comply with government regulations and avoid penalties.
- Cost-Effective: Saves money in the long run by reducing water bills.
- Public Health: Reduces the spread of diseases caused by contaminated water.
