Sewage Treatment Plant - 100m3 Per Day

A 100 KLD STP is designed to treat 100,000 litres of sewage per day, converting wastewater into reusable or environmentally safe discharge water.

Treatment Process

Typical stages include:

1. Screening & grit removal removes large solids
2. Equalization tank stabilizes flow
3. Biological treatment (MBBR / SBR / MBR) breaks down organic matter
4. Secondary clarifier sludge separation
5. Tertiary treatment filtration + UV/chlorination

These systems remove:

• Suspended solids
• Organic pollutants (BOD/COD)
• Oil & grease
• Pathogens and bacteria

STPs are essential to prevent water pollution and enable reuse, converting sewage into usable water

Typical Technical Specs

• Capacity: 100 KLD (100,000 L/day)
• Technology: MBBR / SBR / MBR
• Power consumption: ~10 kW to 40 kW
• Material: RCC / Mild Steel / FRP
• Automation: Semi or fully automatic
• Footprint: Medium to large (prefab systems reduce space)

Advanced STPs (like MBBR/MBR) improve efficiency and reduce operational effort

Applications

• Large apartments (250500 residents)
• Hotels & resorts
• Hospitals
• Malls & commercial complexes
• Medium-scale industries

Price Range (India)

• Basic systems: 8L 12L
• Mid-range: 12L 18L
• Advanced/premium: 18L 30L+

Key Buying Tips

• Best overall MBBR system (low maintenance + stable output)
• Highest water quality MBR system
• Strict TNPCB norms go for tertiary + automation
• Large project RCC civil STP (long life)
• Limited space prefabricated modular STP

Simple explanation

A 100 KLD STP is like a full-scale water recycling plant for a large building or facilitytreating all sewage and turning it into reusable water for flushing, gardening, HVAC, or cooling systems.

Final recommendation

• Choose MBBR + fully automatic for most projects
• Upgrade to MBR if you need high-quality reuse
• Always design based on actual sewage load + Tamil Nadu Pollution Control Board norms
