Your STP should work.
Not trouble you.
Bioman BioSTP is India's non-electric sewage treatment system — trusted by 400+ commercial projects across South India, built to run without power, operators, or breakdowns.
Why most STPs become a headache after installation
Across India, thousands of sewage treatment plants fail — not because of bad design, but because they're too complex for real-world conditions.
- 01
Power failure stops treatment
Conventional STPs depend on continuous electricity — the moment power cuts, treatment stops.
- 02
Frequent breakdowns
Motors, blowers and moving parts wear out and demand constant repair.
- 03
Operator dependency
Trained operators are required every single day to keep the system compliant.
- 04
High AMC cost
Annual maintenance contracts and repairs quietly drain ₹2–5 lakhs a year.
How Bioman solves this
Bioman BioSTP is engineered to work silently in the background — no daily attention required. Once installed, it runs on gravity and biology, not machinery.
- No moving parts
- No electrical dependency
- No daily supervision
- Stable performance year after year
Anaerobic Biodigestion Reactor Technology (ABRT)
A proven natural process where microorganisms break down waste without oxygen or electricity — sewage flows by gravity, solids settle and decompose, and clear, odour-free water flows out.
Settler / Equalization Tank
Two–three chambers, 16–24 hrs retention, traps heavier solids before flow continues.
Anaerobic Baffle Reactor
Up-flow chambers in series; sedimentation + anaerobic digestion remove suspended solids.
Biofilm Filter Media
Biofilm on filter media traps and degrades finer suspended organic particles.
Reed Bed / PGF
Graded gravel + plants (Reed, Canna, Cyperus) treat remaining pollutants naturally.
Disinfection / Ozonation
Chlorine or ozone dosing destroys bacteria, viruses and cysts before discharge.
Percolation Wells
Treated water goes to gardening, irrigation, flushing, or safe ground disposal.
Real installations. Lab-verified results.
Every claim here is backed by field installations across South India and third-party test data — not lab theory.
