Turbidity

Turbidity helps reveal how particulate conditions in the incoming water are changing. Read it alongside the organic signal to understand the coagulation duty.

Dissolved organic carbon

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

Explore parameter
Wastewater

Phosphorus

Phosphorus information helps define the chemical-removal duty. Influent solids and organic material can also contribute to the dose required by the works.

Suspended solids

Incoming solids and organic-demand indicators help define the chemically enhanced pre-treatment duty and the downstream objective.
