Determination of Turbidity
Determination of Turbidity

Turbidity is a very important parameter, whether it is drinking water, domestic water or industrial water used in the production of food, soft drinks and similar beverages. Turbidity is very high in domestic and industrial wastewater and rainwater. Turbidity is not acceptable in drinking water and beverages.

There are many substances that cause turbidity in any water. Planktons, suspended substances and a number of organic substances are the leading ones. Turbidity adversely affects the optical properties of water and prevents the passage of light. This has very dangerous consequences for aquatic life.

The basic principle of turbidity measurements in laboratories is based on how much light is absorbed by the turbidity and allows it to pass through. There are many methods of analysis based on this principle to determine the turbidity of water.

Among the physical analyzes carried out within the scope of food analyzes, turbidity determination analyzes are also included. These analyzes are performed in laboratories that are authorized by local and foreign accreditation institutions.

These laboratories comply with the accepted test methods and test criteria, follow scientific researches and apply the standards published by local and foreign organizations in their studies. Turbidity determination analysis is based on the following standard:

  • TS EN ISO 7027-1 Water quality - Determination of turbidity - Part 1: Quantitative method

This standard uses two different methods to determine the degree of turbidity of water: nephelometry and optical turbidimeter measurement.

The nephelometry method is a common radiation measurement procedure and is applied to low turbidity waters such as drinking water.

The turbidimeter method is the measurement procedure for measuring a radiant flux reduction and is applied for extremely turbid water such as wastewater or rainwater.
