Colour

Online colour monitoring is carried out in drinking water treatment works to monitor the raw water for organic content and ensure its removal throughout the treatment process. A colour analyser typically measures the absorbance at 400nm or in the UV region of the spectrum to determine the apparent colour of the water, and if a turbidity correction factor is applied to this, the true colour can also be determined.
