Read the water
Dissolved organic carbon adds context that a turbidity reading alone cannot provide. Optical measurements can help follow organic changes relevant to coagulation.

Discuss your measurementsWhat the signal can tell you
Particulate and dissolved-organic signals can peak at different times. A falling turbidity trend may coincide with a rising organic signal.

Connect the model
Read incoming organic information alongside turbidity. Compass EOR adds treated-water optical feedback for an agreed enhanced organics-removal objective.
Agree the evidence
Confirm the instrument generation, optical parameter, DOCeq calibration, reference laboratory method and sample points.
The measurement arrangement and control objective are agreed for the works. Performance is assessed against site evidence.

Read incoming turbidity and dissolved organic carbon (DOC) alongside the calculated dose. In this example, the dose responds to rising organics even while turbidity falls.

Illustrative UI only. Fictional values; trends use separate relative scales. DOC is shown as an optical equivalent (DOCeq). Site-specific calibration and validation are required.
A clearer river can still carry an organic signal.
The visual appearance of water cannot establish its dissolved-organic content. In a changing catchment, particulate and organic signals may follow different timings. Reading an optical organic trend beside turbidity gives the control review a second perspective; laboratory comparison establishes what the optical result means for that source water.
Is optical DOC the same as a laboratory DOC result?
An optical DOC equivalent is related to the absorbing organic fraction and the applicable calibration. Its relationship to laboratory DOC must be assessed for the site.
