Villages, hotels, schools, housing schemes and business parks with their own treatment system need the same thing as a large works: enough oxygen and mixing for the bacteria to treat the wastewater. Compact floating aerators add or top up aeration in small tanks and basins from 0.5 metres deep.

## When does a small treatment system need more aeration?

- The load has grown, for example more houses, rooms or visitors
- Odour from a tank that is going septic
- Results drifting towards the licence limits
- Existing aeration has failed or is too small

## Why floating aerators for small systems?

They install without emptying the tank, need no civil works, and are reached from the edge for checks. Units come in a range of sizes, so a small tank is not oversized.

## What should I send with an enquiry?

- Tank or basin size and depth
- What it serves (houses, rooms, people)
- Power available nearby
- Any licence limits or recent results

## Frequently asked questions

### Is there a floating aerator small enough for a small tank?
