Catholyte is a basic solution that, in addition to having excellent cleaning properties, also acts well against heavy metals, favouring flocculation.

	pH	ORP (mv)	Active Chlorine (mg/l)
Catholyte	11.0 - 13.0	-800 - -900	0

Chlorine is not present in this solution, as it is produced by the portion of cathodic cell in which there are no negative ions (anions) including chlorine.

Catholyte Composition

Component	Symbol	Quantity	N° EINECS
Water	H2O	99.30%	231-791-2
Sodium chloride	NaCl	0.413%	231-598-3
Sodium Hydroxide	NaOH	0.14%	215-185-5
Hydrogen Peroxide	H2O2	0.0735%	231-765-0
Ion hydroxide   (Sodium Hydroxide)	OH-	0.0735%	215-185-5

As can be seen from the table, the main compounds that develop within the reactor are sodium hydroxide and hydrogen peroxide (oxygenated water).
Alkaline Catholyte has a pH between 11 and 13: it can be used for flocculation (e. g. heavy metals), coagulation, washing, extraction.
Alkaline Catholyte is also used to wash wounds as a replacement for iodine and in all those applications where it is necessary to increase the pH level of the water to be treated.
