Types of Effluent Treatment Plants at VEPL
Customized Solutions Based on Wastewater Composition
Understanding that wastewater varies significantly in nature across industries, VEPL offers two main types of ETP systems:
🔹 1. Physico-Chemical ETP
Designed for industrial wastewater containing non-biodegradable pollutants, such as heavy metals, oils, chemicals, and suspended solids. These systems utilize processes like:
- Coagulation & Flocculation
- pH Correction
- Sedimentation & Filtration
Best suited for:
Textile | Electroplating | Paint | Chemical | Pharmaceutical industries
🔹 2. Biological ETP (HYBRID ETP – ETP cum STP)
For mixed wastewater containing biodegradable organic matter (from kitchens, toilets, etc.) commonly found in:
Hotels , Hospitals , Hostels , Commercial Complexes , Residential Societies
To meet these unique requirements, VEPL has developed the HYBRID ETP – an advanced treatment system that integrates both Effluent Treatment Plant (ETP) and Sewage Treatment Plant (STP) technologies.
This ETP cum STP efficiently handles high BOD and COD loads using biological processes (Aerobic, MBBR, SBR, etc.), while also addressing physical and chemical impurities.
Ideal for:
Commercial Establishments | Mixed-Use Facilities | Institutions | Urban Wastewater Applications
How Biological & Hybrid ETPs Work:
- Primary Treatment:
- Screening, Oil & Grease Removal, Equalization
- Secondary (Biological) Treatment:
- Activated Sludge Process (ASP)
- Moving Bed Biofilm Reactor (MBBR)
- Sequential Batch Reactor (SBR)
- Anaerobic Treatment (where applicable)
- Tertiary Treatment (Optional):
- Sand/Carbon Filtration, UV/Chlorine Disinfection
- Polishing for Reuse or Safe Discharge
