Turbiditet

Turbiditet refers to the cloudiness or haziness of a fluid caused by large numbers of individual particles that are finely dispersed in the fluid. This is typically a concern in water, where turbidity can be caused by suspended matter such as clay, silt, algae, or other microorganisms. The term originates from the Latin word "turbidus," meaning "cloudy" or "disturbed." Measuring turbiditet is important in various fields, including environmental science, water treatment, and quality control. High turbiditet in drinking water can indicate the presence of harmful pathogens, even if the water appears clear to the naked eye.

In aquatic environments, turbiditet can affect light penetration, impacting the growth of aquatic plants and the behavior of fish. It can also clog the gills of fish and other aquatic organisms. Various instruments, such as turbidimeters, are used to quantify turbiditet, typically by measuring the amount of light scattered by the suspended particles. Lower turbiditet generally signifies clearer water. Processes like sedimentation, filtration, and coagulation are employed to reduce turbiditet in water treatment. The presence of turbiditet is a key indicator of the physical quality of water.
