To know the degree to which water loses its transparency, it is necessary and indispensable in the quality of drinking water; the measurement of turbidity requires the use of a light beam, this is known as the incident light beam, with defined characteristics, in order to determine the semiquantitative presence of particulate material present in water or any fluid sample.
When we filter water using any properly functioning filtration system, the turbidity of the effluent is monitored with a turbidity meter, this instrument has a beam of incident light that detects the material present in water, which causes the light beam to scatter and this scattered light detects and quantifies in relation to a traceable calibration standard.
