Turbidity, a crucial indicator of water clarity, reflects the degree to which suspended matter in water obstructs light transmission. High turbidity may indicate the presence of large amounts of microorganisms, organic matter, or inorganic particles in the water, posing a potential threat to human health. Turbidity is a key indicator for assessing water purification effectiveness and is essential in drinking water treatment, wastewater treatment, industrial process control, and environmental monitoring.
Applications
A turbidimeter, also known as a turbidity meter, is used in water plants, power plants, industrial and mining enterprises, laboratories, and field applications to test the turbidity of water samples. Turbidimeters are widely used in drinking water treatment, wastewater treatment, industrial process control (such as papermaking, textiles, and food processing), environmental monitoring, pharmaceuticals, power generation, and beverage industries for real-time or sampling turbidity monitoring to ensure water quality safety and process optimization. This instrument is often an essential testing device required for drinking water plants applying for QS certification.

Turbidity, or the degree of cloudiness in water, is caused by trace amounts of insoluble suspended matter and colloidal substances. The unit of measurement used in ISO standards is FTU (turbidity unit), which is consistent with NTU (turbidity measurement unit). The brewing industry uses EBC (extracorporeal membrane oxygenation), where 4 FTU = 1 EBC.
Other units of turbidity measurement include JTU (Jackson Turbidity Unit) and ASBC (American Society of Brewing Chemists). International standards such as ISO 7027 (infrared light method) and US EPA Method 180.1 (white light method) are common measurement standards.
