Effluent Treatment Plant (ETP)
Industrial Wastewater Treatment Solutions
Where Industrial Effluent Comes From
Industrial wastewater is generated across many sectors, including textiles, pharmaceuticals, chemical processing, tanneries, food and dairy units, laundries, engineering units, and more.
These effluents often contain colour, organic load, chemicals, oils, and suspended solids that must be treated before discharge or reuse.
Effluent Treatment Plants (ETPs) installed by Togreen Infra Private Limited are designed to remove high levels of organic matter, solids, oils, heavy metals, and other pollutants from industrial wastewater. Using a combination of physical, chemical, and biological processes, these systems make the treated water safe for discharge or suitable for non‑potable reuse, depending on client requirements.
Why Effluent Treatment Is Essential
Protecting environment and ensuring regulatory compliance
Environmental Protection
Contaminated water cannot be released directly into the environment because it may contain toxic and non‑toxic substances harmful to people, soil, and aquatic life.
Water Source Protection
If left untreated, this wastewater can pollute surface and groundwater sources, damage ecosystems, and violate statutory pollution control norms.
Regulatory Compliance
Industries must comply with CPCB and SPCB statutory pollution control norms to operate legally and avoid penalties.

ETP Process Overview
Effluent treatment with Togreen Infra is a multi-stage operation
Preliminary Stage
Large solids removal, oil and grease interception via inlet screens and chambers.
Primary Stage
Sedimentation, chemical coagulation & flocculation in equalization tanks and clarifiers.
Secondary Stage
Organic matter degradation using bacteria, aeration tanks, or MBBR systems.
Tertiary Stage
Advanced filtration, UV or RO, ensuring legal discharge standards.
