HYBRID/ETP CUM STP /MIX BIOLOGICAL ETP (INDUSTRY WISE)
Hybrid Effluent Treatment Plant (Hybrid ETP) Solutions
At Ventilair Engineers Pvt. Ltd. (VEPL), we have introduced the term “Hybrid Effluent Treatment Plant (Hybrid ETP)” to describe systems where multiple wastewater treatment technologies—physical, chemical, aerobic, and anaerobic biological processes—are integrated into a single, unified solution.
This hybrid approach is particularly effective in industries where a single treatment method is not sufficient to handle the complex mix of biodegradable and non-biodegradable pollutants. Earlier referred to as “Mix Biological ETP” or “ETP cum STP”, these systems are now categorized under the Hybrid ETP model for greater clarity and technological distinction.
Why VEPL Hybrid ETP?
Hybrid ETPs offer a comprehensive, flexible, and sustainable solution for facilities generating complex effluents containing:
- High BOD (Biochemical Oxygen Demand)
- COD (Chemical Oxygen Demand)
- Suspended solids, oils, and grease
- Organic and inorganic industrial contaminants
By combining conventional and advanced treatment technologies, VEPL’s Hybrid ETPs help clients meet stringent discharge norms, reuse objectives, and Zero Liquid Discharge (ZLD) requirements.
Industries Benefiting from VEPL’s Hybrid ETPs
- Hospitals & Mortuaries
- Commercial Kitchens & Dairy Plants
- Leather Tanneries
- Rice Mills & Agro Industries
- Pharmaceutical Manufacturing
- Food & Beverage Units
- Hospitality Sector
- Chemical & Dye Industries
- Textile & Pulp and Paper Industries
VEPL’s Hybrid ETP – Key Treatment Stages
- Preliminary (Physical) Treatment
Removes large, suspended, and floatable solids:
- Screening: Eliminates plastics, rags, and coarse solids.
- Grit Chamber: Settles sand and other heavy particles.
- Oil & Grease Trap: Captures oils and greases.
- Primary (Chemical) Treatment
Conditions the wastewater for biological treatment:
- pH Correction and Chemical Dosing
- Coagulation & Flocculation: Using agents like alum or PAC.
- Primary Sedimentation: Settles chemical flocs and suspended solids.
- Secondary (Biological) Treatment
Uses microbial action to degrade organic pollutants.
Aerobic Treatment Technologies:
- Activated Sludge Process (ASP): Ideal for medium-to-large scale applications.
- Moving Bed Biofilm Reactor (MBBR): Compact, low-maintenance, and effective for space-limited sites.
- Sequential Batch Reactor (SBR): Time-based, energy-efficient, and suitable for fluctuating loads.
Anaerobic Treatment Technologies:
- Upflow Anaerobic Sludge Blanket (UASB): Excellent for high-strength wastewater.
- Anaerobic Digesters: Break down solid organic waste while generating biogas, reducing disposal costs.
- Tertiary (Advanced) Treatment
Polishes the effluent and ensures final discharge quality:
- Sand or Activated Carbon Filtration
- Disinfection: Using UV or Ozonation
- Reverse Osmosis (RO) and Ultrafiltration (UF): For high-purity recovery and ZLD applications
- Sludge Handling and Management
Efficiently processes biological and chemical sludge:
- Sludge Thickening and Dewatering (Filter Press)
- Drying Beds or Mechanical Presses
