For buildings and townships, the best STP technology depends on space, load variation and the reuse quality you need. MBBR is compact and handles changing loads well; SBR treats in batches in one tank; extended aeration is simple and robust where space allows.
The full process is explained in our ETP and STP process guide.

Available models
| Technology | Best for | Notes |
|---|---|---|
| MBBR | Limited space, variable load | Plastic media carries the biomass; compact footprint |
| SBR | Batch flows, buildings | Fill, aerate, settle and decant in one tank |
| Extended aeration | Where space is available | Simple and robust; larger tanks |
| MBR | High reuse quality, very little space | Membranes replace the settling tank |

FAQs
How is an STP sized?
On daily sewage flow in KLD, usually estimated from the number of people and the water use per person, plus the inlet BOD and the reuse quality you need.
What can treated STP water be used for?
Toilet flushing, gardening, cooling tower make-up and washing, depending on local rules and the treatment level.
Do you supply STP spares?
Yes: diffusers, blowers, MBBR media, dosing pumps, filter media, multiport valves and instruments.
