Description

Technical Field

[0002] Water quality is the abbreviation of water quality. It indicates the physical (such as color, turbidity, odor, etc.), chemical (content of inorganic and organic matter) and biological (bacteria, microorganisms, plankton, benthic organisms) characteristics of water and its composition.

[0003] Chlorine water is an aqueous solution of chlorine gas. Saturated chlorine water is light yellow-green and has a pungent odor. Chlorine water is divided into freshly produced chlorine water and aged chlorine water. Freshly produced chlorine water, due to the reaction of chlorine gas with water, produces the following main components: Cl₂, H₂O, HClO, H₆, ClO₆, Cl₆, and OH₆. Aged chlorine water, due to the decomposition of hypochlorous acid by light, can be seen as hydrochloric acid.
