What does NTU stand for and what is its purpose?

NTU stands for Nephelometric Turbidity Units, which are utilized for measuring the clarity of water. This unit is significant because it assesses the turbidity, a key water quality parameter that indicates the presence of suspended particles in water. Turbidity can affect the aesthetic quality of water and can also have implications for water treatment processes. High levels of turbidity can indicate potential problems with pathogens, since these particles can harbor and protect microorganisms from disinfection processes. Therefore, measuring turbidity in NTU is vital for ensuring the safety and quality of drinking water, making it a crucial metric in water supply practices.
