PureLife AquaPack 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.
A sewage treatment plant delivered in one FRP unit.
Anaerobic, aerobic and disinfection stages arrive pre-plumbed inside a corrosion-proof fibreglass vessel. No civil tanks to cast, no site-welding, no surprises. Just set, connect and treat.
Proven where it counts.
The PureLife AquaPack Packaged STP.
AquaPack 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.
1 m³ to 500 m³ per day.
Two form factors: horizontal cylinders for villas, apartments and small hotels; vertical / modular units for factories, campuses and townships. Pick by daily flow.
| Model | Capacity (m³/day) | Typical users served | Best fit | Form |
|---|---|---|---|---|
| AP-1 | 1 – 3 | 15–50 persons | Duplex, small villa | Horizontal |
| AP-5 | 5 – 10 | 50–120 persons | Apartment (6–10 flats) | Horizontal |
| AP-25 | 20 – 30 | 200–350 persons | Residential complex, clinic | Horizontal |
| AP-50 | 40 – 60 | 500–650 persons | Hotel, office tower | Vertical |
| AP-100 | 90 – 110 | 1,000+ persons | School, hospital wing | Vertical |
| AP-250 | 200 – 260 | Large campus / factory | Garments unit, township | Modular |
| AP-500 | 450 – 500 | Industrial estate | Smart city, IT park | Modular |
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.
