Determination of Turbidity in Water

Turbidity analysis is an important test parameter in drinking water, water used in the production of food and beverages. Water turbidity can have many causes. These:

Suspended substances such as clay and silt
Plankton
Organic and inorganic substances
Dissolved organic compounds giving color

The turbidity of water used in food is primarily evaluated in terms of cleanliness. The basis of turbidity analysis can be expressed as evaluating the sample according to its absorption or scattering of light.

Different test methods are used for turbidity analysis in water. One of these methods is the formazin method. In the formazin method, the light scattering feature is used in clay and turbid natural waters. Formazine polymer is used as a turbidity suspension.
