Online turbidity analyser
How clear the effluent is, measured continuously as scattered light
Turbidity is the cloudiness of water: the light scattered by particles in it, measured in NTU. At an outlet it is a fast indicator of how well the plant is settling and filtering, and it comes from the same probe as COD, BOD and TSS.

About turbidity
- A quick check of clarity
- A rise in turbidity is often the first sign of a settling or filtration problem.
- Not the same as TSS
- Turbidity is optical, TSS is weight; both are reported, each in its own unit.
- Bubbles and fouling
- Kept out of bubbles and cleaned on a schedule, like the rest of the probe.
- For the operator
- Shown on the panel and the dashboard, with an alert if it crosses a limit you set.
Questions
Do the boards require turbidity?
Not as a rule for effluent; your consent decides. It is measured as standard and is useful to the operator.
Can turbidity replace TSS?
No. The boards ask for TSS in mg/L. Turbidity helps the plant see changes quickly.
