STP and ETP Plant – Sustainable Water Treatment by Koshish India
                     STP and ETP Plant – Clean Water Solutions by Koshish India
Introduction
Water pollution is one of the biggest challenges we face today. Every home, office, and factory
generates wastewater that can harm the environment if not treated properly.
To prevent this, STP (Sewage Treatment Plant) and ETP (Effluent Treatment Plant) are used to
clean and recycle wastewater before it is released or reused.
At Koshish India, we provide reliable, efficient, and eco-friendly STP and ETP solutions to help
communities and industries manage wastewater responsibly.
What is an STP (Sewage Treatment Plant)?
An STP is a system that treats wastewater generated from residential and commercial areas —
such as apartments, offices, hotels, and institutions.
Its main goal is to remove harmful impurities from sewage water and make it safe for reuse or safe
discharge.
How an STP Works:
1. Primary Treatment: Removes solid waste and floating particles.
2. Secondary Treatment: Uses biological processes (microorganisms) to break down organic
matter.
3. Tertiary Treatment: Filters and disinfects the water using UV or chlorine before it is reused.
Where Treated Water Can Be Used:
- Gardening and irrigation
- Toilet flushing
- Construction activities
- Cooling towers
Installing an STP helps reduce water wastage and supports environmental sustainability.
What is an ETP (Effluent Treatment Plant)?
An ETP is designed to treat wastewater coming from industries and manufacturing units.
This water often contains oils, chemicals, and heavy metals that must be removed before disposal.
How an ETP Works:
1. Preliminary Treatment: Removes large particles, oil, and grease.
2. Primary Treatment: Uses chemical processes to separate solids and impurities.
3. Secondary Treatment: Uses biological treatment to remove dissolved organic matter.
4. Tertiary Treatment: Final polishing of water through filtration and pH correction.
Industries That Use ETP Plants:
- Textile and dyeing industries
- Chemical and pharmaceutical units
- Food and beverage industries
- Paper and pulp manufacturing
- Metal and automobile industries
At Koshish India, our ETP systems are designed as per Pollution Control Board (PCB) norms,
ensuring full compliance and high performance.
Difference Between STP and ETP
Source of Wastewater: STP handles domestic water; ETP handles industrial water.
Pollutant Type: STP treats organic waste; ETP treats chemical waste.
Main Process: STP uses biological methods; ETP uses chemical + biological methods.
Water Reuse: STP water can be used for gardening, flushing, irrigation; ETP water can be reused
in industrial processes or safely discharged.
