Thank you Sir. What is the turbidity of drinking water?

[@FoodTechInfomedia]

Turbidity represents the physical characteristic of water.It is an extent to which light is absorbed by particles in the water. It depends on the fineness of particle present in the water.According to WHO, the permissible limit for drinking water is 5NTU.The value of turbidity measured by nephelometer is expressed in terms of NTU. Sometimes, it is referred as FTU or Formazin turbidity unit.
