Case Study: 100 KLD STP Project for Popular Hospital, Varanasi
Project Overview
- Client: Popular Hospital
- Location: Varanasi, Uttar Pradesh
- STP Capacity: 100 KLD (Kilo Liters per Day)
- Technology: MBBR (Moving Bed Biofilm Reactor)
- Application: Hospital/Hotel/Residential Society/Industry (customize)
Background & Requirement
Popular`Hospital needed a modern, low-maintenance STP to meet new UPPCB and NGT rules, ensure 100% compliance, and enable treated water reuse for gardening and flushing. Site constraints required a compact design with minimal civil work.
Design & Execution
- Process selection: MBBR for high efficiency and small footprint
- Modular tanks—fully underground, RCC with anti-corrosion coating
- Energy-efficient blowers and automated dosing system
- Control panel with alarms, auto-start, and online monitoring provision
- AMC (Annual Maintenance Contract) for 3 years
Key Challenges
- Limited space for plant—solved with custom RCC tank layout
- High groundwater level during excavation—special waterproofing done
- Required zero odor—installed odor control units and proper venting
Performance & Results
| Parameter | Raw Sewage | Treated Water | UPPCB Limit |
|---|---|---|---|
| BOD (mg/L) | 250–350 | <15 | ≤20 |
| COD (mg/L) | 450–600 | <50 | ≤100 |
| TSS (mg/L) | 150–250 | <20 | ≤30 |
- Consistent treated water quality—100% within norms
