Significance of Use
Used in natural water based applications, such as drinking water and municipal wastewater treatment, the color of water may dictate the presence of both unwanted inorganic and organic material; removal results in more suitable water for general and industrial applications. “Color” is applied in this context to represent “true color”, where turbidity is removed. Where turbidity removal has been omitted, the term “apparent color” is then applied.
