**Quick answer** A sewage treatment plant (STP) treats domestic sewage from toilets, kitchens and bathrooms so the water can be reused for flushing, gardening or cooling, or discharged safely. Filtsap builds STPs using MBBR, SBR or extended aeration with screening, equalisation, aeration with diffusers, settling, sand and carbon filtration, chlorination or UV, and sludge handling.

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](https://www.filtsap.com/guides/etp-stp-process/) .

## 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.
