PureLife EcoPack STP.
Built for Bangladesh.
A factory-assembled, plug-and-treat sewage treatment plant in a single FRP shell — engineered for load-shedding, monsoon inflow and DoE compliance. From apartment blocks in Uttara to garments factories in Gazipur, one plant treats it all.

Proven where it counts.
The PureLife EcoPack Packaged STP.
EcoPack is a factory-built sewage treatment plant — screening, equalisation, anaerobic and aerobic biological treatment, clarification and disinfection integrated inside a single fibreglass-reinforced plastic (FRP) vessel. Designed for Bangladeshi conditions — grid outages, high water tables and heavy monsoon inflow — it replaces sprawling RCC tanks and years-long civil work with a plant you can commission in under a week.
Why buildings choose it
Built to comply
Configured to meet Department of Environment (DoE) discharge norms and the Environment Conservation Rules, ready for reuse in flushing and landscaping.
DoE ECR-2023 CETP / STP norms Reuse-ready outlet RAJUK-friendly footprint Green-building compatibleHow the treatment works.
Screening
Coarse solids and grit removed before they reach the biology.
Equalisation
Buffers peak-hour and monsoon inflow into a steady, even load.
Anaerobic
First-stage biological breakdown reduces organic load.
MBBR Aerobic
Moving-bed media grows the biomass that does the heavy lifting.
Clarifier
Settles treated water clear; sludge is returned or wasted.
Disinfection
Chlorine / UV polish delivers reuse-grade, safe outlet water.
Find your EcoPack. 1 KLD to 500 KLD.

The Sequencing Batch Reactor (SBR) Sewage Treatment Plant.
For projects that demand the highest outlet quality in the smallest footprint, PureLife builds SBR-based sewage treatment plants. SBR treats sewage in timed batches inside a single tank — aeration, settling and decanting all happen in one basin, one cycle at a time — giving you sharper control, cleaner water and a compact plant that fits Bangladesh’s tight urban sites.
What is an SBR Sewage Treatment Plant?
A Sequencing Batch Reactor is a fill-and-draw activated-sludge system. Instead of flowing continuously through separate tanks, sewage is treated in repeating time-based cycles within one reactor. The same basin fills, aerates, settles and decants in sequence — so a single tank does the work of several.
Why choose SBR over conventional STP?
The 5 Stages of an SBR Cycle.
Fill
Screened sewage enters the reactor basin until the working volume is reached.
React (Aerate)
Blowers supply oxygen; microorganisms break down the organic load.
Settle
Aeration stops and biomass settles as a clear supernatant forms above.
Decant
The clarified treated water is drawn off the top by the decanter.
Idle / Sludge
Excess sludge is wasted and the basin resets for the next batch.
Key Benefits of PureLife SBR Plants
Smallest footprint per m³ Superior nutrient removal No return-sludge pumping loop Absorbs peak & shock loads Fully automated PLC control Low operator dependence Consistent DoE-grade outlet Easy future expansionSBR Plant Technical Specifications
Where SBR Plants Fit Best.
Large residential townships
High, variable domestic flows where footprint and outlet quality both matter.
Hotels & commercial complexes
Batch control keeps effluent consistent despite fluctuating occupancy.
Industrial & garments estates
Handles shock loads and delivers reuse-grade water for factory operations.
Outlet quality that exceeds DoE norms.

EcoPack is engineered to be objectively better than the two systems most builders default to: a civil RCC ASP plant, and a bare-bones MS-tank packaged STP from a generic supplier.
| Attribute | PureLife EcoPack | Civil RCC STP (ASP) | Generic MS Packaged STP |
|---|---|---|---|
| Treatment technology | Anaerobic + MBBR (dual) | ASP / Extended aeration | SAFF or basic MBBR |
| Vessel material | 100% FRP — corrosion-proof, 50-yr life | RCC — joints leak after 5–8 yrs | Mild Steel / epoxy — 10–15 yrs |
| Footprint (per KLD) | ~ 0.6 m²/KLD | ~ 1.5 m²/KLD | ~ 0.9 m²/KLD |
| Install time (50 KLD) | 3–5 days | 4–8 weeks | 2–3 weeks |
| Power consumption | Low (silent diaphragm) | High (continuous aeration) | Moderate |
| On-site operator | Not required (auto + IoT) | Full-time required | Part-time required |
| Sludge generation | ~30% less than ASP | High | Moderate |
| CPCB Class A outlet | ✓ Exceeds | Variable | Borderline |
| Reuse-ready | Direct flushing & irrigation | Needs tertiary | Needs tertiary |
| OCEMS / SCADA | PLC + IoT, OCEMS-ready | Add-on cost | Rare |
| Warranty | 10-yr module + lifetime service | 1 year | 1–2 years |
| Total 25-yr cost (50 KLD) | Lowest TCO | +35% (rebuild after yr 12) | +18% (replace yr 12) |
